This separates code relying on inline from that relying on external
assembly and fixes instances where the coalesced check was incorrect.

CAVS uses its own idct so using dsputil to set the permutation
is fragile.

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.

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.

The ParserContext class doesn't have an AVClass, required for

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.

This assert is no longer true since h264 error concealment needs
last_picture_ptr to be set.

The data in coded_frame isn't allocated using get_buffer, but
is copied from the input frame to the encoder, so we should
not try to free it ourselves.
This fixes an assert failure when running in debug mode.

Previously, the put_bits call writing the value wrote a value
larger than the number of bits specified, failing asserts
in debug mode. There was no actual bitstream writer corruption,
since the overwritten bit already always was set to 1.

Previously, the value given to put_bits was 10 bits long for positive
predictors, even though 9 bits were to be written. The extra bit could
in some cases overwrite existing bits in the bitstream writer cache.
This fixes a failed assert in put_bits.h, when running a version
built with -DDEBUG.
The fate test result gets slightly improved, thanks to getting rid
of the overwritten bits in the bitstream writer cache.

This way it won't interfere with WMV9 initialisation inside MSS2 decoder and
avplay will play it fine.

Some optimized template functions reference optimized symbols, so they
must be explicitly disabled when those symbols are unavailable.

The optimized dct_quantize template functions reference optimized
fdct symbols, so these functions must only be enabled if the relevant
optimizations have been enabled by configure.

This avoids trouble if HAVE_ variables are used elsewhere in the file.
