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.

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.

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.

Changed to use QueryPerformanceCounter on Windows rather than only
when building with MSVC, so that MSVC can link libs built with
MinGW.

Fixes issue #149.

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.

There was an extremely rare deadlock that happened when one thread
was waiting to start the loop filter on frame n while the other
threads were starting to work on frame n+1.

These changes improve the behaviour of the code with
forced key frames sent in by a calling application.

The sizing of the frames is still suboptimal for two pass in
particular but the behaviour is much better than it was.

make the arm asm detokenizer work with the new structures

The main reason for the change was to reduce cycles in the token
decoder. (~1.5% gain for 32 bit)  This layout should be more
cache friendly.

As a result of this change, the encoder had to be updated.

Note: dixie uses a similar layout

The memory being zeroed in vp8_update_mode_info_border() was just
 allocated with calloc, and so the entire function is actually
 redundant, but it should be made correct in case someone expects
 it to actually work in the future.

The timebase was being set to the value in the Y4M file on each
 pass, but only doubled to account for the altref placement on
 the first past.
This avoids reseting it on the second pass.

--cpu was already implemented for most of our embedded
platforms, this just extends it to x86.  Corner case for
Atom processor as it doesn't respond to the --march=
option under icc.

mbmi and eob moved in previous commits

Change-Id: I30a2eba36addf89ee50b406ad4afdd059a832711

Moving the eob structure allows for a non-struct based
function to handle decoding an entire mb of
idct/dequant/recon data.  This allows for SIMD functions
to idct/dequant/recon multiple blocks at once.

SSE2 implementation gives 3% gain on Atom.

The external API exposes the RC initial/optimal/full buffer level in
milliseconds, but this value was truncated internally to seconds. This
patch allows the use of the full precision during the conversion from
time to bits.

This reverts commit 6ea5bb85.

move some things around, reorder some instructions

constant 0 is used several times. load it once per call in horiz,
once per loop in vert.

separate saturating instructions to avoid stalls.

just use one usub8 call to set GE flags, rather than uqsub8 followed by
usub8 w/ 0

document some stalls for further consideration

The C version of the dequant/idct/add function depends on the C
version of the IDCT, but this isn't compiled in on ARM. Since this
code has asm version, we can just remove this file to eliminate the
link error.
