system: do not overwrite /bin/sh Busybox symlink

The BR2_SYSTEM_BIN_SH hidden option defines to what binary the /bin/sh
symlinks should point to. If busybox is chosen, then /bin/sh is created
to point to /bin/busybox.

This works fine with the default installation mode of Busybox, but it
fails with the upcoming "individual binaries" mode, in which each applet
is installed as its own binary, and /bin/busybox doesn't exist: we get
/bin/sh as a broken symlink to /bin/busybox.

Since Busybox already installs its own /bin/sh symlink, properly
pointing to /bin/ash or /bin/hush depending on the selected shell, it
doesn't make sense for the BR2_SYSTEM_BIN_SH logic to override
this. Just let Busybox install its own /bin/sh by making
BR2_SYSTEM_BIN_SH empty when Busybox shell is selected as /bin/sh.

core: enhance printvars

Currently, the output of printvars copntains the name of the variable,
its expanded value and its un-expanded value.

However, most of the time, we need the actual, expanded value, so it can
be re-used from a (non-Buildroot) infrastructure script, like a
post-build script, or a build-farm driver (e.g. a Jenkins job...)

Add two options that a user may set to change the output of printvars:
  - QUOTED_VARS, if set, will quote the value
  - RAW_VARS, if set, will print the unexpanded value

The new output by default only prints the expanded value now.

So that it can be used as such:

    $ make -s printvars VARS=BUSYBOX_VERSION
    BUSYBOX_VERSION=1.26.2

    $ make -s printvars VARS=BUSYBOX_RDEPENDENCIES QUOTED_VARS=YES
    BUSYBOX_RDEPENDENCIES='ncurses util-linux'

    $ make -s printvars VARS=BUSYBOX_FINAL_PATCH_DEPENDENCIES RAW_VARS=YES
    BUSYBOX_FINAL_PATCH_DEPENDENCIES=$(sort $(BUSYBOX_PATCH_DEPENDENCIES))

And it is even possible to directly evaluate it in a shell script:

    eval $(make -s printvars VARS=BUSYBOX_VERSION QUOTED_VARS=YES)

Backward compatibility of the output is not maintained. It is believed
that scripts that depended on the previous output were very fragile to
begin with, because they had to filter the non-formatted output
(splitting on spaces or braces was not really possible, because values
could contain either).

Document printvars and its options in the manual; list it in the output
of 'make help'.

gdb: pass gdb_cv_prfpregset_t_broken=no

Starting with glibc 2.25, the proc_service.h header has been copied
from gdb to glibc so other tools can use it. However, that makes it
necessary to make sure that declaration of prfpregset_t declaration
is consistent between gdb and glibc. In gdb, however, there is a
workaround for a broken prfpregset_t declaration in glibc 2.3 which
uses AC_TRY_RUN to detect if it's needed, which doesn't work in
cross-compilation. So pass the cache option to configure.
It needs to be passed to GDB_CONF_ENV to build gdbserver only but
also to GDB_MAKE_ENV, because otherwise it does not get passed to the
configure script of nested packages while building gdbserver with full
debugger.

gdb: add upstream patch to fix inconsistency with glibc header

In glibc 2.25, the proc_service.h header was copied from gdb to glibc.
However, in the process the 'const' was removed, which leads to build
failures with glibc >= 2.25.

gdb 7.12.1 already contains this patch. The patch for 7.11.1 comes
straight from upstream, the patch for 7.10.1 is backported by me.

samba4: security bump to version 4.5.7

Fixes CVE-2017-2619:

   All versions of Samba prior to 4.6.1, 4.5.7, 4.4.11 are vulnerable to
   a malicious client using a symlink race to allow access to areas of
   the server file system not exported under the share definition.

   Samba uses the realpath() system call to ensure when a client requests
   access to a pathname that it is under the exported share path on the
   server file system.

   Clients that have write access to the exported part of the file system
   via SMB1 unix extensions or NFS to create symlinks can race the server
   by renaming a realpath() checked path and then creating a symlink. If
   the client wins the race it can cause the server to access the new
   symlink target after the exported share path check has been done. This
   new symlink target can point to anywhere on the server file system.

   This is a difficult race to win, but theoretically possible. Note that
   the proof of concept code supplied wins the race reliably only when
   the server is slowed down using the strace utility running on the
   server. Exploitation of this bug has not been seen in the wild.

core/br2-external: properly report unexpected errors

Unextected error in the br2-external script are properly caught, but
they are not reported properly, and we end up in either of two
situations:

  - the .br2-external.mk file is not generated, in which case make will
    try to find a rule to generate it (because the 'include' directive
    tries to generate missing files);

  - the .br-external.mk file is generated but does not contain the error
    variable, and thus the build might not get interrupted.

We fix that by using a trap on the pseudo ERR signal, to emit the error
variable on unexpected errors.

   [PATCH] Change the install location of _sysconfigdata.py

was dropped due to the fact taht build system now adds platform
specific suffix to sysconfigdata's name, so each platform's file
should have a unique name and distutils now allows to specify which
sysconfigdata is used via _PYTHON_SYSCONFIGDATA_NAME

see:

    https://github.com/python/cpython/commit/c4b53afce491142b80b228a21a05de5dcfd8d36f
    https://github.com/python/cpython/commit/92dec548ff1494b86f08bd3753ca91a9330b4ea9

and patches:

    [PATCH] distutils/sysconfig: use sysconfigdata
    [PATCH] setup.py: do not add invalid header locations
    [PATCH] Do not harcode invalid path to ncursesw headers

was dropped since it looks like it made it's way upstream, see:

    https://github.com/python/cpython/commit/409482251b06fe75c4ee56e85ffbb4b23d934159

qt: add enable for truetype font installation

Currently, qt.mk installs DejaVu/Vera TrueType fonts when Qt is configured for
freetype support. However, some users may prefer to limit the installed fonts
to only Qt's prerendered fonts (micro, fixed, helvetica, etc.). Or, there may
be a preference to use seperately installed TrueType fonts. This commit adds
a switch to explicitly control the installation of the TrueType fonts, similar
to the existing prerendered font enables.

vnstat: bump to version 1.17

Also remove patch that has been merged upstream, disable AUTORECONF
since we're no longer patching configure.ac and get rid of hack
involving the install target as the 'install-data-hook' in Makefile.am
now avoids running 'vnstat --showconfig' on the host in case of

busybox: fix mdev.conf

mdev does not set "/dev/snd" and "/dev/input" group and permission
propery, because with commit c3cf1e30a3022453311a7e9fe11d94c7a381640e
(May 2013!) the behavior of mdev has changed.

The device name is now taken directly from the uevent file and does no
longer match the old rule.

Fix the rules for "/dev/snd" and "/dev/input" according to the example
given in [1].
