f857a85088 Restructure multi-threaded decoder
On each MB, loopfiltering is done right after MB decoding. This
combines two loops in multi-threaded code into one, which reduces
number of synchronizations to half.

The above-row/left-col data are saved in temp buffers for
next-row/next MB decoding.

Tests on 4-core gLucid machine showed 10% decoder performance
gain with threads=4 (tulip clip). Testing on other platforms
isn't done yet.

147b125b15 Reduce size of tokenizer tables
This patch reduces the size of the global tables maintained by the
tokenizer to 16k from 80k-96k. See issue #177.

746439ef6c Modify GET_GOT macro for performance.
GET_GOT was producing a zero length call.  This resulted in
pipeline flushes occuring when returing from the assembly
functions.  Masked on out of order cores, but evident on
Atom cores.

00cec8f9e9 Changed code to remove extra read/write loops when not necessary
Modified code so that:
-When above and left contexts are same and not equal to current segment id, it needs to read a maximum of 2 segment_tree_probabilities.
- When above and left contexts are different and not equal to current segment id, it needs to read only a single segment_tree_probability.

769f2424cc Removed unnecessary pxor.
There is no need to make sure that the lower byte of the
register is 0 because the downshift by 11 overwrites that byte.

be7e4e854c Delta updates to segmentation map using left and above contexts.
-Updates by making use of spatial correlation.
-Checks if the segment_id is same as above or left context and encodes only the update to the map instead of updating individual segment_ids.

a65cd3def0 Make block access to frame buffer sequential

c5fb0eb8d9 Improved subset block search
Improved the subset block search and fill.  (about 3% improvement for
32 bit)  Modified/merged the code in order to create
vp8_read_mb_modes_mv which can decode the modes/mvs on a macroblock
level. This will allow the decode loop (in the future) to decode
modes/mvs on a frame, row, or mb level.

14ba764219 Update NEON wide idcts
Expand 93c32a55 which used SSE2 instructions to do two
idct/dequant/recons at a time to NEON. Initial working
commit. More work needs to be put into rearranging and
interlacing the data to take advantage of quadword
operations, which is when we'll hopefully see a much
better boost

edcbb1c199 Fix GF interval for non-lagged ARFs
When ARFs are enabled in non-lagged compress modes, the GF interval
was being reset to zero. Non-lagged ARF updates were enabled in commit
63ccfbd, but this incorrect GF interval caused a quality regression.

69ae8f475d Skip unnecessary search of identical frames
vp8_get_compressed_data() was defeating logic in
encode_frame_to_datarate() that determined the reference buffers to
search and forcing all frames to be eligible to search. In cases
where buffers have identical contents, this is unnecessary extra
work.

63ccfbd545 Enable ARFs for non-lagged compress
ARFs were explicitly disabled except in lagged compress mode. New
ARF logic allows for the ARF buffer to hold an older golden frame,
which does not require lagged compress.

0de458f6b9 Reduced the size of MB_MODE_INFO
Moved partition_bmi and partition_count out of MB_MODE_INFO and
placed into MACROBLOCK.  Also reduced the size of other members
of the MB_MODE_INFO struct.  For 1080p, the memory was reduced
by 1,209,516 bytes.  The decoder performance appeared to improve
by 3% for the clip used.
Note:  The main goal for this change is to improve the decoder
performance.  The encoder will be revisited at a later date for
further structure cleanup.

76640f85da encoder: remove postproc dependency
Remove the dependency on postproc.c for the encoder in general, the only
unchecked need for it is when CONFIG_PSNR is enabled. All other cases
are already wrapped in CONFIG_POSTPROC. In the CONFIG_PSNR case the file
will still be included.

Additionally, when VP8_SET_POSTPROC is used with the encoder when post
processing has been disabled an error will be returned.

This addresses issue #153.
