support/testing: switch to Python 3 only

Python 2.7 will not be maintained past 2020.

Many scripts on the tree are used during the build and should keep
Python 2 compatibility for a while.
This is not the case for the runtime test infra. It's meant to be run in
modern distros only, so it can safely switch to support Python 3 only.

An advantage of this approach is to have less scenarios to test in.
Otherwise every change to the test infra or runtime tests would need to
be tested against both versions of the interpreter, increasing the
effort of the developers, to ensure the compatibility to Python 2 was
not broken.

In order to accomplish the change to Python 3:
 - change the shebang for run-tests;
 - use Python 3 urllib as a drop-in replacement for Python 2 urllib2;
 - when writing the downloaded binary files, explicitly open the output
   file as binary;
 - when subprocess is used to retrieve the text output from commands,
   explicitly ask for text output. For this, use 'universal_newlines'
   because 'text' was added only on Python 3.7;
 - when pexpect is used to retrieve the text output from qemu or git,
   explicitly ask for text output using 'encoding';
 - the code using csv currently follows the example in the documentation
   for the Python 2 module, change it to follow the example in the
   documentation for the Python 3 module;
 - fix the relative import for test_git.py to be Python 3 compliant.

package/go: security bump to version 1.13.3

Fixes the following security issues (1.33.2):

- CVE-2019-17596: Invalid DSA public keys can cause a panic in dsa.Verify.
  In particular, using crypto/x509.Verify on a crafted X.509 certificate
  chain can lead to a panic, even if the certificates don’t chain to a
  trusted root.  The chain can be delivered via a crypto/tls connection to a
  client, or to a server that accepts and verifies client certificates.
  net/http clients can be made to crash by an HTTPS server, while net/http
  servers that accept client certificates will recover the panic and are
  unaffected.

Additionally, 1.13.3 fixes a number of issues. From the release notes:

package/gpsd: Fix systemd service installation and paths

Fix several issues with systemd service file installation for gpsd:

- systemd support in the gpsd build was defaulting to enabled or not
based on whether the host system had systemd directories present. Set
this explicitly based on whether BR2_INIT_SYSTEMD is set.

- The installed systemd service files referenced paths in /usr/local when
the actual binaries are installed in /usr. Replace /usr/local with /usr
in the installed service files.

- When BR2_PACKAGE_HAS_UDEV was enabled, all of the binaries were
re-installed again, along with the udev rules, as part of the
post-install hooks. This overwrites the service files that were just
fixed up. Since udev-install implies install, we can just call
udev-install.

package/busybox: udhcpc.script: wait for ipv6 default route from RA for stateful DHCPv6

udhcpc6 implements "stateful" DHCPv6 for explicitly requesting an address
and other configuration information. A major difference between DHCPv4
and DHCPv6 is that DHCPv6 does *not* advertise a default route; this is
determined by normal IPv6 autoconfiguration.

Add logic to wait up to IF_WAIT_DELAY seconds for the IPv6 route to be
configured; as above this doesn't come from DHCPv6 but rather the IPv6
Router Advertisement (RA) which happens independently from udhcpc6.  The
intent here is to try and ensure that the interface is route-able upon the
script's completion as it would be if called from udhcpc.

package/musl: Make scheduler functions Linux-compatible

The POSIX functions sched_getscheduler(), sched_setscheduler(),
sched_getparam(), sched_setparam() are technically not correctly
implemented by the Linux syscalls of the same name, because what the
kernel calls a PID and what POSIX calls a PID isn't truly the same,
resulting in somewhat different semantics as to what these functions
exactly apply to.
Details: https://sourceware.org/bugzilla/show_bug.cgi?id=14829

Since the musl developers put a high premium on POSIX compliance, they
deliberately implement these functions to return -ENOSYS instead of
relaying them to the respective Linux syscalls as glibc/uClibc do.

Unfortunally this breaks virtually all Linux programs using these
functions under musl. For example running 'chrt -p 1' fails with
'Function not implemented' on a musl-libc based system.
In particular, it affects embedded systems using these interfaces
for scheduling real-time processes.

As it seems unfeasible to fix all affected programs to manually use
syscall wrappers instead of the libc functions, make musl behave the
Linux way.

toolchain/toolchain-external: restrict copying of dynamic loader to ld*.so.*

Commit 32bec8ee2fb00c6750fa842bbb0eb79b0c081fa2
("toolchain-external: copy ld*.so* for all C libraries") changed (among
other things) the glob pattern to catch the dynamic loader from
    ld*.so.*
to
    ld*.so*

thus now matching files like 'ld-2.20.so' in addition to files like
'ld.so.1'.

However, there is no apparent reason why that change was made. It is
not explicitly mentioned in the commit message as to why that would be
needed, nor is clear based on the rest of the changes in that
commit. But it turns out that it causes too many files to be copied
with some toolchains.

In most toolchains, the structure looks like this:

-rwxr-xr-x 1 tdescham tdescham 834364 Feb 16 21:23 output/target/lib/ld-2.16.so
lrwxrwxrwx 1 tdescham tdescham     10 Feb 16 21:23 output/target/lib/ld.so.1 -> ld-2.16.so

So, a symlink 'ld.so.1' which points to another file. Applications
would have 'ld.so.1' (the link) encoded as program interpreter
(readelf -l <program>, see INTERP entry)

The patterns like 'ld*.so*' are passed as argument to
copy_toolchain_lib_root which is defined in toolchain/helpers.mk.
This macro copy_toolchain_lib_root will find all files/links matching
the pattern. If a match is a regular file, it is simply copied. If it
is a symbolic link, the link is copied and then the logic is
recursively repeated on the link destination. That destination could
either again be a link or a regular file. In the first case we recurse
again, in the latter we stop and continue with the next match of the
pattern.

The problem this patch is solving is when a toolchain does not have
this structure with a link and a real file, but rather two actual
files:

-rwxr-xr-x 1 tdescham tdescham 170892 Feb 16 21:55 output/target/lib/ld-2.20.so
-rwxr-xr-x 1 tdescham tdescham 170892 Feb 16 21:55 output/target/lib/ld.so.1

In this case the pattern 'ld*.so*' would find two regular file matches
and copy both. On the other hand, the pattern 'ld*.so.*' would only
find the 'ld.so.1' file and copy just that. This saves about 170K in
rootfs size.

Closer inspection reveals that this particular toolchain has more such
dedoubled symbolic links, e.g. the standard pattern of
'usr/lib/libfoo.so -> libfoo.so.1 -> libfoo.so.1.0.2' is not present,
and each of these three components are real files. In any case, it is
obvious that the toolchain itself is 'broken'.

That being said, because we have the logic that recursively resolves
symbolic links, TOOLCHAIN_EXTERNAL_LIBS really only needs to contain
the "initial" name of the library to be copied.

Therefore, revert the glob pattern back to what it was.

package/meson: install cross-compilation.conf during toolchain install

package/meson installs a cross-compilation.conf file in
$(HOST_DIR)/etc/meson, via TARGET_FINALIZE_HOOKS.

package/pkg-cmake.mk installs a toolchainfile.cmake in
$(HOST_DIR)/share/buildroot, via TOOLCHAIN_POST_INSTALL_STAGING_HOOKS.

Both files have a similar concept, they describe some flags/paths needed for
compilation using respective build systems. One difference is that the meson
file is added for external compilation, from the SDK, while the cmake file
is used internally in Buildroot.

The 'problem' of using TARGET_FINALIZE_HOOKS for the meson file, is that it
installs a 'host' file from target-finalize, which is conceptually incorrect
since not just TARGET_DIR but also HOST_DIR is "regenerated" on a subsequent
'make' when everything was already built (i.e. only target-finalize is run).

This can easily be fixed, by using the same hook as cmake uses, i.e.
TOOLCHAIN_POST_INSTALL_STAGING_HOOKS.

Note that actually even for cmake, TOOLCHAIN_POST_INSTALL_STAGING_HOOKS is
not the best hook to install a host file. A better hook would have been
TOOLCHAIN_POST_INSTALL_HOOKS, but this triggers only for 'host' packages,
and 'toolchain' is treated as a 'target' package.

Also, the hook (and therefore also the definition of
PKG_MESON_INSTALL_CROSS_CONF) is moved to pkg-meson.mk, again to make it
more similar to how it's done for cmake. Otherwise check-package
complains that the meson package is setting variables that don't start
with MESON_.

package/*: do not override LICENSE, but append to it

Now that the infra takes care of removing extraneous spaces before
commas, we can safely append to LICENSE variables.

This removes the only case where we had to use immediate assignment
to append to a variable.

Mechanical change, with:

    $ sed -r -i -e 's/\<([^[:space:]]+_LICENSE) := \$\(\1\),/\1 += ,/' \
        $(git grep -l -E '\<([^[:space:]]+_LICENSE) := \$\(\1\),')

core/legal-info: don't require overriding _LICENSE

Currently, the formatting we impose on the _LICENSE variable requires
that we also use the rarely used := assignment operator, which makes
the _LICENSE variable the only variable that users have to write with
this operator.

This really departs from the simplicity and consistency of using the
append-assignment, which we use for every other variable.

This is because the append-assignment operator surreptiously
introduces a space between the original value and the appended one. But
we can use this knowledge, to match any instance of a space followed by
a comma, and turn it into a single comma.

This allows users to now have a consistent use of the '=' and '+='
operators we use everywhere else in .mk files.

package/libopenssl: set no-asm with generic architectures

Use no-asm when building with generic architectures such as gcc or
linux-generic32, see https://github.com/openssl/openssl/issues/9839

This will fix a static build failure on x86_64 due to the removal of
x86/x86_64 BSAES and AES_ASM support by
https://github.com/openssl/openssl/commit/87bea6550ae0dda7c40937cff2e86cc2b0b09491
