This is the first modification of VP8 multi-thread decoder, which uses
same threads to decode macroblocks and then do loopfiltering for each
frame.

Inspired by Rob Clark, synchronization was done on every 8 macroblocks
instead of every macroblock to reduce lock contention.

Comparing with the original code, this implementation gave about 15%-
20% performance gain while decoding my test clips on a Core2 Quad
platform (Linux).

The work is not done yet.

Test on other platforms are needed.

Clang defaults to C99 mode, and inline works differently in C99.
(gcc, on the other hand, defaults to a special gnu-style inlining,
which uses different syntax.)   Making the functions static makes sure
clang doesn't decide to discard a function because it's too large to
inline.

Thanks to eli.friedman for the patch.

Fixes http://code.google.com/p/webm/issues/detail?id=96

The regex which postprocesses the gcc make-deps (-M) output was too
greedy and matching in the dependencies part of the rule rather than
the target only. The patch provided with the issue was not correct, as
it tried to match the .o at the end of the line, which isn't correct
at least for my GCC version. This patch matches word characters
instead of .*

Thanks to raimue and the MacPorts community for isolating this issue.

new quantizer can be switched back and forth by define or
un-define the macro "EXACT_QUANT".

The assembly version of the quantizer has not been updated to match
the new exact quantizer introduced in commit e04e2935. That commit tried
to disable this code but missed the non-RTCD case.

issue and testing this fix.

* changes:
  Change the x86 idct functions to do reconstruction at the same time
  Combine idct and reconstruction steps

Jeff Muizelaar posted some changes to the idct/reconstruction c code.
This is the equivalent update for the arm assembly.

This shows a good boost on v6, and a minor boost on neon.
Here are some numbers for highway in qcif, 2641 frames:
HEAD neon: ~161 fps
new neon:  ~162 fps
HEAD v6:   ~102 fps
new v6:    ~106 fps

The following functions have been updated for armv6 and neon:
vp8_dc_only_idct_add
vp8_dequant_idct_add
vp8_dequant_dc_idct_add

Conflicts:

	vp8/decoder/arm/armv6/dequantdcidct_v6.asm
	vp8/decoder/arm/armv6/dequantidct_v6.asm

Resolved by removing these files. When I rewrote the functions, I also
moved the files to dequant_dc_idct_v6.asm/dequant_idct_v6.asm

This moves the prediction step before the idct and combines the idct and
reconstruction steps into a single step. Combining them seems to give an
overall decoder performance improvement of about 1%.

At the end of the decode, frame buffers were being copied.
The frames are not updated after the copy, they are just
for reference on later frames.  This change allows multiple
references to the same frame buffer instead of copying it.

Changes needed to be made to the encoder to handle this.  The
encoder is still doing frame buffer copies in similar places
where pointer reference could be done.

Merge commit 'refs/changes/51/351/1' of ssh://review.webmproject.org:29418/libvpx into KfRateBugMerged

In two pass encodes, the calculation of the number of bits
allocated to a KF group had the potential to overflow for high data
rates if the interval is very long.

We observed the problem in one test clip where there was one
section where there was an 8000 frame gap between key frames.

This replaces the approximate division-by-multiplication in the
 quantizer with an exact one that costs just one add and one
 shift extra.
The asm versions have not been updated in this patch, and thus
 have been disabled, since the new method requires different
 multipliers which are not compatible with the old method.
