Apparently this include is needed on some systems for building the
poll fallback (for the timeval struct for select?), but it isn't
available on all systems. Thus only include it if it exists.

This heaader is required for close() for sockets in network
code. For winsock, the equivalent function is defined in the
winsock2.h header.

This avoids having the HAVE_UNISTD_H in all files dealing with
raw sockets.

Move private fields to the private section, remove holes.

Place related fields together, remove holes.

Place related fields together, remove holes, move private fields to the
end and mark them as private.

It is not used in any filters currently and is inherently evil. If
passing binary data to filters is required in the future, it should be
done with some AVOptions-based system.

Fixes bug 308.

parse_forced_keyframes() relies in encoder timebase being set, so call
it from transcode_init() after it is known.

The MBAFF flag may only be signaled if we're actually dealing with
a full frame, and not singular fields, as it can happen in mixed content.

In a 64-bit PIC build, external functions must be called
through the PLT.

This is required for isatty, which exists on MSVC and is found by
configure, but is provided by io.h instead of unistd.h.

This adds whitespace around operators, aligns line continuation
backslashes, and breaks long lines.  Also fixes an ifdef halfway
through a statement.  The one line of duplication this saved is
not worth the ugliness.

On MSVC, gmtime returns NULL for values outside of their supported
range (and these show up in our fate test). This doesn't seem
to affect the actual fate test result.

MSVC has isatty (in io.h), but not unistd.h. (isatty isn't called
at all for windows, since there's a special case block for that.)

Tags may contain attached picture, which will be exported as video
streams.

This ensures that the audio stream is always the first.

Right now, it's uint16_t, but for itunes metadata a 32bit number is
stored in it.

Currently if a pattern is given we look for up to the fifth file name in
the sequence. This option sets that limit to an arbitrary number.

This adds the capability to start counting file number from an arbitrary
integer.

This includes a few lines of trivial code from FFmpeg codebase.

Also ensure that all such filters get a non-NULL name. Should fix FATE
failures on some architectures after
58b049f2.

Because of a mistake during merging the code for simple and complex
filtergraphs, -async inserts an asyncts filter both on input and output.
Remove the output hunk.

This removes a dependency on implementation details from generic
code and allows easy addition of the equivalent optimisation for
other architectures than x86.
