Currently, errors are thrown for various macros while building that are completely bogus.
They occur during the dependency (.d) generation phase, and have no bearing on the compiled output,
since only the stdout is piped into the sed command to generate the .d files.
They basically occur as the relevant -I paths are not (and cannot be passed) during
the dependancy generation phase.
As such, this patch silences them.

This patch silences such warnings by placing initializations under a header guard,
see e.g
http://fate.ffmpeg.org/log.cgi?time=20150919095430&log=compile&slot=x86_64-archlinux-gcc-disableswscale,
http://fate.ffmpeg.org/log.cgi?time=20150919095048&log=compile&slot=x86_64-archlinux-gcc-disableswresample
for examples of such warnings.
It also has the benefit of placing library specific #defines next to each other.

This silences some of the -Wunused-function warnings when compiled with --disable-mmx, e.g
http://fate.ffmpeg.org/log.cgi?time=20150919094617&log=compile&slot=x86_64-archlinux-gcc-disable-mmx.
Header guards are too brittle and ugly for this case.

This will give incorrect results in some cases due to not parsing segments
separately, so it currently requires -strict experimental.

This affects Annex B streams (such as demuxed from .ts and others). It
also handles the format change in reinit-large_420_8-to-small_420_8.h264
correctly.

Instead of passing through the extradata, create it on the fly it from
the currently active SPS and PPS. Since reconstructing the PPS and SPS
NALs would be very complicated and verbose, we use the NALs as they
originally appeared in the bitstream.

The code for writing the extradata is somewhat derived from
libavformat/avc.c, but it's small and different enough that sharing it
is not really worth it.
