It is included for the open/read/write/close functions. On
MSVC, where this header does not exist, the same functions
are provided by io.h, which is already included.

On windows, these functions are provided by io.h. Make sure
io.h is included if it exists, regardless of the setmode
function.

unistd.h is used for open/read/close, but if this header does not

unistd.h used to be required for gethostname. On windows, gethostname

winsock2.h if they exist.

AV_LOG_INFO is more geared towards messages to be read by the user, the
statistics shown by libx264 with X264_LOG_INFO are more useful at the
debugging level.

In vp6 Advanced Profile, deblock filtering is conditionally enabled in
each frame header.  In Simple Profile it should always be off.  vp6 was
inheriting the wrong default from ff_vp56_init.

That division can be replaced with a comparison:
((c->value - c->low) << 1) + 1 >= range

By expanding 'range' definition and simplifying this inequation we obtain
the final expression.
