Otherwise we will reference the dependant libraries with -lfoo rather than
/path/to/libfoo.la which breaks with the Android-based .la parser which
simply passes through all -l libraries.

The result of this is undefined and will become a hard error
in a future Meson release.
The documentation of libav says -Bsymbolic may be needed when building a
shared library which links statically to libav.
Fixes linking error on FreeBSD:
gst-libav/gst-libs/ext/.libs/libavcodec.a(simple_idct10.o):
relocation R_X86_64_PC32 against `ff_pw_1023' can not be used when making a
shared object; recompile with -fPIC

Autotools automatically appends user CPPFLAGS after target
CPPFLAGS. Also, it puts all CPPFLAGS before CFLAGS in final
generated gcc compile command. The internal ffmpeg include
paths need to come before any other external include paths
to ensure we don't accidentally pickup external ffmpeg
headers first (i.e. from user CPPFLAGS include paths). Thus,
move the internal LIBAV include paths to LIBAV_CPPFLAGS so
that they come before any user defined CPPFLAGS.
This allows ffmpeg and gst-ffmpeg to coexist on users system.

This reverts commit 4284d791bc.
It causes crashes on various h264 and DNXHD/VC3 streams, where the
decoders write to arbitrary memory far after what we've allocated.
As a side effect, left/right green bars goes away when using
xvimagesink. I just think that xv cropping is broken, so this is
probably just hiding a bug.
While all this information is in the .la files, libtool seems to get
confused with ordering in presence of static system libraries. This could
cause missing symbol error at link time. Adding these depenencies explicitly
workaround the issue.
Add gas-preprocessor.pl as a git submodule, and put it in the
path so that it is available if libav wants it.
Switch back to providing $CC as $AS by default, but
respect an external $AS setting so that it can be
overridden in cerbero
