works around bug in gccs inline asm register assignment
Fixes Ticket3177
gcc from 4.4 to 4.6 is affected at least, no non affected gccs known
clang seems not affected

The CONFIG_ name-space is set by configure, so its better to use a
different prefix here.
This also unifies the encoder & decoder define that is used

This makes the USE_FLOATS == 0 available to the end user
More float optimizations can easily be added as well now
common code should be factored out into a common file once all
fixed point & floating point optimizations are done, this is to
avoid having to move code back and forth between files.

dsputil: x86: Move ff_inv_zigzag_direct16 table init to mpegvideo
If someone optimizes dct_quantize for non x86 SIMD, then this
probably needs to be reverted.

It was previously int and would return error if decode_coeffs_b()
returns an error; however, that can never happen, so refactor all
that code to make all dependent functions return void also (all the
way up to decode_coeffs_sb()).
For a random 1080p sample, decoding time went from 9.7sec (1 threads)
to 6.0sec (2 threads) and 5.2sec (4 threads) in 2-pass decoding mode.
I don't have any samples that use the parallelmode feature, but the
gains should be higher.
We need more information from last/cur_frame than from reference
buffers, so we can use a simplified structure for reference buffers,
and then store mvs and segmentation map information in last/cur.
