The function call was a mess to handle, and memcpy cannot make
the assumptions we do in the new code.

Tested on an IMC sample: 430c -> 370c.

Apparently, some build environments require dxva.h even for dxva2,
while others lack this header entirely.  Including it conditionally
allows building in both cases.

This gives you the proper v4 or v6 version of the "any address",

It is a plain int now.

Changed to match the number of parameters in conv_func_interleave(), which is
how they are called. The change isn't strictly necessary because the 4th
parameter is not used, but the code is clearer if they match.

This adds a fallback for cbrtf() using powf(x, 1/3).  Since
powf() with a non-integer exponent requires a non-negative
base, special handling of negative inputs is needed.

Since the errno.h values don't match the error codes that winsock
returns, map the winsock error codes to the errno ones, to make
sure explicit checks against AVERROR(x) match.

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.

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.

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.

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.
