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
exist, there's probably no use in trying to open /dev/*random
at all.

unistd.h used to be required for gethostname. On windows, gethostname
is provided by winsock2.h. Now network.h includes both unistd.h and
winsock2.h if they exist.

For some reason add_hfyu_median_prediction_cmov is only selected
on 3Dnow-capable CPUs, even though it uses no 3Dnow instructions.
This patch allows it to be selected on any cpu with cmov with the
possibility of being overridden by the mmxext version.

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.
Help reducing the log spam.
This fixes crashes when called from rtpdec_qt, where
AVFormatContext->pb is null, a crash present since 3bab7cd128.

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.

Print
FOURCC: PIX_FMT
rather than
PIX_FMT: FOURCC
This seems more consistent with the help message:
-l list the pixel format for each fourcc
Remove possibly redundant/confusing comment.
It calculates the sum of power of two series, which can be done in one step.

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.

Prevents dangling pointers and makes access after free more obvious.
Setting AVFrame.qscale_table to NULL is required for successfully
allocating a previously freed Picture with ff_alloc_picture().
