core: catch failures in graph-depends

Currently, we generate the dependency graph in a single command, piping
the stdout of support/scripts/.graph-depends to the stdin of dot.

Unfortunately, this means we can't catch a failure of graph-depends, as
the shell can only treturn the exit code of the last command in a pipe.

Still, we do want to keep the output of graph-depends, and we in fact do
keep it by mean of a tee.

graph-depends has just gained the ability to generate its output to a
file, so we break the pipe in two differnet commands, so we can bail out
on graph-depends errors.

Do that for the two call sites.

support/graph-depends: add option to specify output file

Currently, graph-depends outputs the dotfile program to stdout, and uses
stderr to trace the dependencies it is currently looking for.

Redirection was done because the output was directly piped into the dot
program to generate the final PDF/SVG/... dependency graph, but that
meant that an error in the graph-depends script was never caught
(because shell pipes only return the final command exit status, and an
empty dot program is perfectly valid so dot would not complain).

Add an option to tell graph-depends where to store the generated dot
program, and keep stdout as the default if not specified.

package/avahi: break circular dependencies

We currently have two circular dependency chains:

    avahi -> libglade -> libgtk2 -> cups -> avahi
    avahi -> libgtk3 -> cups -> avahi

The cups -> avahi dependency makes sense, as cups would be able to use
Bonjour and mDNS to find printers, so we want to keep that dependency.

The libgtk2 -> cups and libgtk3 -> cups dependencies also make sense, to
be able to offer cups in the print dialogs.

However, the avahi -> libglade and avahi -> libgtk3 dependencies do not
really make sense. As Thomas puts it:

    The avahi GUI programs seem really useless to me. On Debian/Ubuntu
    distributions, they are not even packaged within the main avahi
    packages, but as separate packages, probably indicating that they
    are not very commonly used.

So, we drop the avahi -> libglade and avahi -> libgtk3 dependencies, to
break the circular dependency chain.

package/openpowerlink: bump to v2.2.2

From [1]:
With version 2.0, the source code has been cleanly split into
an application-oriented user library and a time-critical stack
driver. The latter may be moved to a dedicated communication
processor or into a kernel module to deliver enhanced
performance while still keeping the API in user space.

This new version break the API used in the v1.x but
this is a complete rewrite of the Powerlink EPSG DS 301
implementation. The v1.x is deprecated anyway.

The new build system has been split in several CMake projects
which makes it difficult to package with the Buildroot CMake
infra. So add a top level CMakeLists.txt to build each
openpowerlink component without having to package each of them
in a separate Buildroot packages. Also we need to fix the
build system to support the top level CMake build.

support/scripts: add size-stats-compare script

Leverage the CSV files produces by size-stats (make graph-size) to allow
for a comparison of rootfs size between two different buildroot
compilations.

The script takes the file-size CSV files of two compilations as input, and
produces a textual report of the differences per package.
Using the -d/--detail flag, the report will show the file size changes
instead of package size changes.
The -t/--threshold option allows to ignore file size differences smaller
or equal than the given threshold (in bytes).

Example output is:

Size difference per package (bytes), threshold = 0

thrift: remove BR2_ARCH_HAS_ATOMICS dependency

squid: rework atomic handling

squid can use the __sync built-ins when available, but uses an
AC_TRY_RUN autoconf tests to check their availability, which isn't
compatible with cross-compilation. Due to this, squid.mk is already
hinting the configure script about this by passing
squid_cv_gnu_atomics=yes/no depending on the availability of atomic
operations.

So far, squid.mk was assuming that BR2_ARCH_HAS_ATOMICS &&
BR2_ARCH_IS_64 was needed, since 8 bytes __sync built-ins are
used. However, this was a bit too restrictive, since certain 32 bits
architectures (ARM, x86) do provide 8 bytes __sync built-ins.

So, instead of using BR2_ARCH_HAS_ATOMICS, we now rely on
BR2_TOOLCHAIN_HAS_SYNC_4 and BR2_TOOLCHAIN_HAS_SYNC_8, since both 4
bytes and 8 bytes __sync built-ins are tested by the autoconf test.

cairo, harfbuzz: rework atomic dependencies

This commit handles the reverse dependency tree of cairo in terms of
atomic dependencies. There are two main changes:

 - cairo in fact no longer needs atomic operations. It can perfectly
   build without any __sync built-in, as was tested using an ARC
   toolchain without atomics, and a SPARC toolchain. Optionally, Cairo
   can use the __atomic builtins provided by gcc >= 4.7, so support
   for this is added as well. Thanks to this change, the
   BR2_ARCH_HAS_ATOMICS dependency is removed from cairo and all its
   reverse dependencies.

 - harfbuzz does require the __sync built-in for 4 bytes integers, so
   we add a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 to harfbuzz and all
   its reverse dependency, the main one being the pango package. Due
   to this, the vast majority of gtk-related packages are moved to a
   dependency on BR2_ARCH_HAS_ATOMICS (which used to be due to cairo)
   to a dependency on BR2_TOOLCHAIN_HAS_SYNC_4 (due to pango ->
   harfbuzz).

In detail:

 - cairo

   Remove BR2_ARCH_HAS_ATOMICS dependency, link against -latomic when
   gcc >= 4.8 in order to use the __atomic functions.

 - harfbuzz

   Add dependency on BR2_TOOLCHAIN_HAS_SYNC_4

 - cairomm, gst-plugins-good, gst1-plugins-good, libgdiplus,
   libsvg-cairo, weston

   Remove BR2_ARCH_HAS_ATOMICS dependency (since cairo no longer needs
   atomics)

 - enlightenment, cwiid, gst-plugins-bad, gst-plugins-base,
   gst1-plugins-bad, gst1-plugins-base, gtkmm3,
   libevas-generic-loaders, libfm, libgail, libgtk2, libgtk3, librsvg,
   openbox, opencv, opencv3, pango, pangomm, pcmanfm, pinentry,
   rrdtool, webkit, webkitgtk24, xscreensaver

   Switch from a BR2_ARCH_HAS_ATOMICS dependency to a
   BR2_TOOLCHAIN_HAS_SYNC_4 (they depend on pango, harfbuzz, gtk, or
   some other related package)

 - directfb

   Remove BR2_ARCH_ATOMICS dependency of the BR2_PACKAGE_DIRECTFB_SVG
   (since cairo can build without atomics), but add a
   BR2_TOOLCHAIN_HAS_SYNC_4 dependency on BR2_PACKAGE_DIRECTFB itself
   since it does use __sync built-ins. This replaces the !BR2_sparc

gauche: disable on SPARC(64), remove atomics dependency

gauche does not build on sparc64, it fails with:

  No rule to make target 'sparc_mach_dep.lo', needed by 'libgc.la'

On Sparc, it first fails with the usual "membar" assembler issue which
comes from gauche's internal version of libatomic_ops. However, even
passing -DAO_NO_SPARC_V9 like we do for libatomic_ops is not
sufficient, as we fall into the same build problem as on sparc64.

Consequently, this commit disables the gauche package on the sparc and
sparc64 architectures.

Since it uses its own libatomic_ops copy, and libatomic_ops does not
have any dependency on atomic built-ins, we also remove the
BR2_ARCH_HAS_ATOMICS dependency. It was originally added to prevent
gauche from being built on sparc, but this will no longer happen.

apache, apr: fix atomic handling

pulseaudio: remove BR2_ARCH_HAS_ATOMICS dependency

pulseaudio is able to either use the atomic __sync builtins from the
compiler, or to rely on libatomic_ops for atomic operations. However,
since it anyway selects json-c which requires the __sync built-ins, it
means using libatomic_ops is useless: even if you use libatomic_ops
for pulseaudio, you'd still get a link error in pulseaudio due to the
missing __sync built-in for the json-c library.

Also, since pulseaudio now inherits the BR2_TOOLCHAIN_HAS_SYNC_4 from
json-c, which matches the __sync built-in from pulseaudio, this
commit:

 - Drops the BR2_ARCH_HAS_ATOMICS dependency
 - Forces pulseaudio to not detect libatomic_ops
 - Propagates the removal of BR2_ARCH_HAS_ATOMICS dependency to
   pulseaudio's reverse dependencies.

json-c: needs __sync_val_compare_and_swap_4

While json-c itself builds fine on platforms that don't provide the
__sync atomic built-ins, it does use them. json-c doesn't fail to
build because only a library is built, so such function calls are left
unresolved. But as soon as it gets used in another package linked in a
program, linking will fail due to the missing
__sync_val_compare_and_swap_4() function.

To fix this, we make json-c depend on BR2_TOOLCHAIN_HAS_SYNC_4, and

toolchain: add BR2_TOOLCHAIN_HAS_{SYNC_x, ATOMIC} hidden booleans

Currently, Buildroot provides one BR2_ARCH_HAS_ATOMICS boolean option
to indicate whether the architecture supports atomic operations or
not. However, the reality of atomic operations support is much more
complicated and requires more than one option to be expressed
properly.

There are in fact two types of atomic built-ins provided by gcc:

 (1) The __sync_*() family of functions, which have been in gcc for a
     long time (probably gcc 4.1). They are available in variants
     operating on 1-byte, 2-byte, 4-byte and 8-byte integers. Some
     architectures implement a number of variants, some do not
     implement any, some implement all of them.

     They are now considered "legacy" by the gcc developers but are
     nonetheless still being used by a significant number of userspace
     libraries and applications.

     https://gcc.gnu.org/onlinedocs/gcc/_005f_005fsync-Builtins.html

 (2) The __atomic_*() family of functions, which have been introduced
     in gcc 4.7. They have been introduced in order to support C++11
     atomic operations. In gcc 4.8, they are available on all
     architectures, either built-in or in the libatomic library part
     of the gcc runtime (in which case the application needs to be
     linked with -latomic). In gcc 4.7, the __atomic_*() intrinsics
     are only supported on certain architectures, since libatomic did
     not exist at the time.

For (1), a single BR2_ARCH_HAS_ATOMICS is not sufficient, because
depending on the architecture, some variants may or may not be
available. Setting BR2_ARCH_HAS_ATOMICS to false as soon as one of the
variant is missing would cause a large number of packages to become
unavailable, even if they in fact use only more common variants
available on a large number of architectures. For this reason, we've
chosen to introduce four new Config.in options:

 - BR2_TOOLCHAIN_HAS_SYNC_1
 - BR2_TOOLCHAIN_HAS_SYNC_2
 - BR2_TOOLCHAIN_HAS_SYNC_3
 - BR2_TOOLCHAIN_HAS_SYNC_4

Which indicate whether the toolchain support 1-byte, 2-byte, 4-byte
and 8-byte __sync_*() built-ins respectively.

For (2), we introduce a BR2_TOOLCHAIN_HAS_ATOMIC, which indicates if
the __atomic_*() built-ins are available. Note that it is up to the
package to link with -latomic when gcc is >= 4.8. Since __atomic_*()
intrinsics for all sizes are supported starting

We conducted a fairly large analysis about various architectures
supported by Buildroot, as well as with a number of different
toolchains, to check which combinations support which variant. To do,
we linked the following program with various toolchains:

int main(void)
{
uint8_t a;
uint16_t b;
uint32_t c;
uint64_t d;

__sync_fetch_and_add(&a, 3);
__sync_fetch_and_add(&b, 3);
__sync_fetch_and_add(&c, 3);
__sync_fetch_and_add(&d, 3);

__sync_val_compare_and_swap(&a, 1, 2);
__sync_val_compare_and_swap(&b, 1, 2);
__sync_val_compare_and_swap(&c, 1, 2);
__sync_val_compare_and_swap(&d, 1, 2);

__atomic_add_fetch(&a, 3, __ATOMIC_RELAXED);
__atomic_add_fetch(&b, 3, __ATOMIC_RELAXED);
__atomic_add_fetch(&c, 3, __ATOMIC_RELAXED);
__atomic_add_fetch(&d, 3, __ATOMIC_RELAXED);

__atomic_compare_exchange_n(&a, &a, 2, 1,  __ATOMIC_RELAXED,  __ATOMIC_RELAXED);
__atomic_compare_exchange_n(&b, &b, 2, 1,  __ATOMIC_RELAXED,  __ATOMIC_RELAXED);
__atomic_compare_exchange_n(&c, &c, 2, 1,  __ATOMIC_RELAXED,  __ATOMIC_RELAXED);
__atomic_compare_exchange_n(&d, &d, 2, 1,  __ATOMIC_RELAXED,  __ATOMIC_RELAXED);

return 0;
}

And looked at which symbols were unresolved. For the __atomic_*()
ones, we tested with and without -latomic to see which variants are
built-in, which variants require libatomic. This testing effort has
led to the following results:

Notes:

 * __atomic built-ins appeared in gcc 4.7, so for toolchais older than
   that, the __atomic column is empty.

 * Y means 'supported built-in'

 * L means 'supported via linking to libatomic' (only for __atomic
   functions)

 * X indicates a very special case for 8 bytes __sync built-ins on
   ARM. On ARMv7, there is no problem, starting from gcc 4.7, the
   __sync built-in for 8 bytes integers is implemented, fully in
   userspace. For cores < ARMv7, doing a 8 bytes atomic operation
   requires help from the kernel. Unfortunately, the libgcc code
   implementing this uses the __write() function to display an error,
   and this function is internal to glibc. Therefore, if you're using
   glibc everything is fine, but if you're using uClibc or musl, you
   cannot link an application that uses 8 bytes __sync
   operations. This has been fixed as part of gcc PR68095, merged in
   the gcc 5 branch but not yet part of any gcc release.

 * - means not supported

This commit only introduces the new options. Follow-up commits will
progressively change the packages using BR2_ARCH_HAS_ATOMICS to use
the appropriate BR2_TOOLCHAIN_HAS_SYNC_x or BR2_TOOLCHAIN_HAS_ATOMIC
until the point where BR2_ARCH_HAS_ATOMICS can be removed.

defconfigs: all use the headers from the kernel

For most defconfigs, it was trivial to deduce the kernel version, by
just reading the version string, which could be:
  - a standard upstream version string vX.Y.Z
  - a non-standard version string, but still containg the standard X.Y.Z

Those for which it was not so trivial were those hosted on git tree.
Since most were already using a custom linux-headers version, it could
be easily deduced from that. It was confirmed by browsing said git trees
and check the version there.

There are a few cases were there was a mismatch:

  - microzed:     uses a 3.18 kernel, but 3.8 headers; fixed.
  - xilinx_zc706: uses a 3.14 kernel, but 3.8 headers; fixed.
  - zedboard:     uses a 3.18 kernel, but 3.8 headers; fixed.

libbsd: upgrade to v0.8.2 and expand architecture support

When libbsd still supported uClibc as a C library, we added the architecture
exclusions because uClibc's a.out.h includes linux/a.out.h. The latter only
exists for the specified architectures.

However, glibc doesn't include linux/a.out.h, it instead has its own
implementation and it adds a flag to indicate if a.out is supported on this
architecture or not.

Since libbsd currently only supports glibc-based toolchains, the architecture
exclusions are no longer valid.

On microblaze, the build still fails, but this time because of ELF support.
libbsd explicitly handles architectures and microblaze is not one of them (see
local-elf.h).

python-cffi: add host variant

Host variant is needed to cross-compile CFFI based C library wrappers.

[Thomas:
 - add dependency on host-pkgconf for the host package variant.
 - add various environment variables needed to make pkg-config behave
   properly when building host-python-cffi. Otherwise, pkg-config
   returns values that are appropriate to build things for the target,
   and the build fails.]

libffi: fix headers location for host-libffi

There is a special hook for target-libffi, that moves headers
from /usr/lib/libffi-version/include to /usr/include. This patch
adds the same procedure for host-libffi.
