Some parameters passed to the av_dlog can be either float or int, depending on
the mode the file is being compiled as.  Cast those parameters to float and use
appropriate conversion specifiers.

Fixes regression in 836f47d34b in ICC-10.x,
since ICC<=11.0 doesn't align stack upon function calls.

Ports the majority of IDCT functions for 10-bit H.264.

Parts are inspired from 8-bit IDCT code in Libav; other parts ported from x264 with relicensing permission from author.

Prior to ARMv6, the destination registers of the SMULL instruction
must be distinct from the first source register.  Marking the
output early-clobber ensures it is allocated unique registers.

This restriction is dropped in ARMv6 and later, so allowing overlap
between input and output registers there might give better code.

This does all the actual bit counting as a final step.

No speed difference. This is to allow for more flexible bit counting.

This will make it easier to access the bap values without having to chase
the reference block pointers each time.

Also deprecate avcodec_get_pix_fmt_name() in its favor.

This silences numerous compiler warnings from skip_bits(),
where the cache variable is not used.

Aligned local variables must use the LOCAL_ALIGNED macro to ensure
correct alignment on all systems.  The unusual size argument to
memset is required since the implementation of LOCAL_ALIGNED may
use a pointer to an array.

This function uses old-style vector operations deprecated in VFPv3.
Some implementations, e.g. Cortex-A9, support them only through
slow software emulation.  Cortex-A8 does have this functionality
in hardware, but as it also has NEON, this function is not used
there regardless.

Uninitialized coefficients were being used to generate exponents, some
of which actually ended up in the final stream.  Even though, they were
just extra exponents that are not used by any decoder, it is still
better to have consistent output for testing. This also fixes valgrind
errors.
