This will allow to error out immediately if incompatible options are
passed on the command line instead of running time-consuming tests.

This avoids unnecessarily linking against xlib.

Also drop a related and now redundant informative output line.

In recent lld-link versions, this command prints the version to
stdout, but also prints an error to stderr:

$ lld-link -flavor gnu --version
LLD 4.0.0 (trunk 285641)
lld-link: error: no input files
lld-link: error: target emulation unknown: -m or at least one .o file required

The four examples (audio/video encoding/decoding) are completely
independent so it makes little sense to have them all in one file.

Avoid an underlink issue on recent distributions.

Unfortunately the xavs.h API header is not self-sufficient and relies
on manual stdint.h inclusion by its users.

It has been replaced by C11 stdatomic.h and is now unused.

Since this is a C11 feature, it requires -std=c11.

Not actually used for anything yet, that will be added in the following
commits.

The latter can do everything the former can do, but also handle conditions
the former cannot like multiple header #includes and checking for headers
and functions in a single test program, which is necessary for certain
library tests.

It no longer serves a useful purpose.

This exposes some required functionality like _aligned_malloc() in the
MinGW system headers, thus obviating the need for the memalign hack.

This allows these flags to be automatically enabled for clang,
when using MSVCRT headers.

This allows doing this redirection, if building with clang against
old enough MSVC headers that lack strtoll (2012 and older).

The setpts filter does not signal to the rest of the filtergraph that
the stream is CFR. Just generate the timestamps manually instead.

When targeting COFF (windows), clang doesn't support this
directive (while binutils supports it for all targets).

This fixes standalone compilation of the SVQ3 decoder, which had
incomplete dependencies related to H.264 parsing.

While it is less featureful (and slower) than the built-in H264
decoder, one could potentially want to use it to take advantage
of the cisco patent license offer.

With compilers that do not support proper dead code elimination, like
Sun C 5.12, linking fails due to missing references to unavailable,
but also unused, symbols.
