bcba86e2e9 Eliminated reconintra_mt.c
Reworked the code to use vp8_build_intra_predictors_mby_s,
vp8_intra_prediction_down_copy, and vp8_intra4x4_predict_d_c
functions instead.  vp8_intra4x4_predict_d_c is a decoder-only
version of vp8_intra4x4_predict.  Future commits will fix this
code duplication.

749bc98618 BLOCKD structure cleanup
Removed redundancies.  All of the information can be
found in the MACROBLOCKD structure.

5a2fd63a2a ARMv6 optimized Intra4x4 prediction
Added ARM optimized intra 4x4 prediction
 - 2x faster on Profiler compared to C-code compiled with -O3
 - Function interface changed a little to improve BLOCKD structure
   access

ed9c66f584 Remove usage of predict buffer for decode
Instead of using the predict buffer, the decoder now writes
the predictor into the recon buffer.  For blocks with eob=0,
unnecessary idcts can be eliminated.  This gave a performance
boost of ~1.8% for the HD clips used.

Tero: Added needed changes to ARM side and scheduled some
      assembly code to prevent interlocks.

Patch Set 6:  Merged (I1bcdca7a95aacc3a181b9faa6b10e3a71ee24df3)
into this commit because of similarities in the idct
functions.
Patch Set 7: EC bug fix.

c4d7e5e67e Eliminate more warnings.
This eliminates a large set of warnings exposed by the Mozilla build
 system (Use of C++ comments in ISO C90 source, commas at the end of
 enum lists, a couple incomplete initializers, and signed/unsigned
 comparisons).
It also eliminates many (but not all) of the warnings expose by newer
 GCC versions and _FORTIFY_SOURCE (e.g., calling fread and fwrite
 without checking the return values).
There are a few spurious warnings left on my system:

../vp8/encoder/encodemb.c:274:9: warning: 'sz' may be used
 uninitialized in this function
gcc seems to be unable to figure out that the value shortcut doesn't
 change between the two if blocks that test it here.

../vp8/encoder/onyx_if.c:5314:5: warning: comparison of unsigned
 expression >= 0 is always true
../vp8/encoder/onyx_if.c:5319:5: warning: comparison of unsigned
 expression >= 0 is always true
This is true, so far as it goes, but it's comparing against an enum, and the C
 standard does not mandate that enums be unsigned, so the checks can't be
 removed.

19638c2309 arm: move unrolled loops back to generic code
Some of the ARM functions differed from their generic counterparts
only by unrolling their loops. Since this change may be useful
on other platforms, or might even supercede the looped version
in the generic case, move it back to the generic file.

This code is left under #if ARCH_ARM for now, but it may be worth
considering a different (possibly new) conditional for these. If
it turns out that this should be runtime selectable, these
functions will have to move to the RTCD infrastructure. Don't want
to take that step at this time without more profile data.

94c52e4da8 cosmetics: trim trailing whitespace
When the license headers were updated, they accidentally contained
trailing whitespace, so unfortunately we have to touch all the files
again.
