When compiled with --disable-pthreads, e.g
http://fate.ffmpeg.org/report.cgi?time=20150917015044&slot=alpha-debian-qemu-gcc-4.7,
a bunch of -Wunused-functions are reported due to missing header guards
around threading related functions.
This patch should silence such warnings.

Glibc 2.20 onwards generates a deprecation warning for usage of _BSD_SOURCE and _SVID_SOURCE.
The solution from man feature_test_macros is to define both _DEFAULT_SOURCE and the old macros.
This solution is on the lines of the one in commit af181827.

Silence a warning due to frame assignment in dvenc. All uses of the
reference in dvdec are read only, except the ones in the main decoding
function, so use the frame pointer directly there.

Silence an uninitialized warning from clang.

Move the demuxers into their own file.

Also slightly faster.
Signed-off-by: Paul B Mahol <onemda@gmail.com>

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.
