A flashsv2 block may have a "diff block" to indicate which scan lines of
the block are actually encoded.  However, this diff block need not be
used when the entire block is coded.

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.

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().

The init functions check for CPU capabilities on their own already.

FFT in MIPS implementation is working iteratively instead
 of "recursively" calling functions for smaller FFT sizes.
Some of DSP and format convert utils functions are also optimized.

It is possible in various error paths as well as gap handling
that this has already been allocated. It is not clear why that
would be a problem with the current code, thus disable the
assert to avoid a common assert failure when asserts are enabled.
