Replace =1 with =true for yasm tool element. This aids in upgrading
e.g., vs9 project files to vs10.
build/x86-msvs/yasm.xml generated during conversion will require the
Separator attribute to be removed for the build to complete
successfully.

Moved encode_intra function from firstpass.c to encodeintra.c to
prevent linking problem in real-time only build. Also changed name
of the function to vp8_encode_intra because it is not a static.

- Updated -linux-rvct targets to support RVDS 4.0 and later.
- Changed optimization flag to -Otime because -O3 ruined performance
  for RVCT linux targets.
- Added support for --enable-small for RVCT
- RVCT created library should be able to link with GCC
- Supports building shared linux libraries

If setup_token_decoder reported an internal error the memory allocated
there would not be freed in the resulting call to _remove_decompressor.

Small decode performance gain (~1%) on keyframes.  No
noticeable gains on encode.  Also changed pick_intra4x4mby_modes()
to read the above and left block modes for keyframes only.

Automatically created assembly offset files added to CLEAN-OBJS list
for proper cleanup. This will fix following build error:
1) Build for the workstation
./conigure
make
make clean
2) Build for ARM platform
./configure --target=armv7-linux-gcc
make ==> this will fail because it uses old asm_*_offset.asm files

call to this set of functions are replaced by var16x16.

Activity update is no longer dependent on being in RD mode, so update
it unconditionally.

Better fix for #326. ICC happens to support the inline magic

Change-Id: Ic367eea608c88d89475cb7b05d73500d2a1bc42b

Broke RVCT. New magic coming for ICC. Stay tuned!

This reverts commit c73eb2ff

Since BPRED will be tested at most once, and SPLITMV is not enabled,
there's nothing to clobber the subblock modes, so there's no need to
save and restore them.

The returned rate was always the 4x4 rate, instead of the rate
matching the selected mode.

In activity masking, RDO constant RDMULT is adjusted on a per MB basis
adaptive to activity with the MB. errorperbit, which is defined as
RDMULT/RDDIV, is a constant used in motion estimation. Previously, in
activity masking, errorperbit is not changed even when RDMULT is changed.
This commit changed to adjust errorperbit according to the change in
RDMULT.

Test in cif set showed a very small but consistent gain by all quality
metrics (average, overall psnr and ssim) when activity masking is on.

This change is analogous to I0b67dae1f8a74902378da7bdf565e39ab832dda7,
which made the move for the non-RD path.

This commit moves the intra block mode selection from encodeframe.c
to pickinter.c (in the non-RD case). This allowed pick_intra_mbuv_mode
and pick_intra4x4mby_modes to be made static, and is a step towards
refactoring intra mode selection in the main pickinter loop. Gave a
small perf increase (~0.5%).

Some further re-structuring of activity masking code.
Still has various experimental switches.
Supports a metric based on intra encode.
Experimental comparison against a fixed activity target  rather
than a frame average, for altering rd and zbin.

Overall the SSIM performance is similar  to TT's original
code but there is a much smaller PSNR hit of circa
0.5% instead of 3.2%

While investigating the effect of DC values on SAD and SSE in motion
estimation, a side finding indicates the two table of constants need
be adjusted. The adjustment was done by multiplying old constants by
90% with rounding. Also absorb the 1/2 scaling constant into the two
tables. Refer to change Ifa285c3e for background of the 1/2 factor.

Cif set test showed a very small gain on all metric.

The encoder defined about 4 set of similar functions to calculate sum,
variance or sse or a combination of them. This commit removed one set
of these functions, get8x8var and get16x16var, where calls to the later
function are replaced with var16x16 by using the fact on a 16x16 MB:
    variance == sse - sum*sum/256

In real-time mode motion search, there is no need to calculate
variance. This change improved encoding speed by 1% ~ 2%(speed=-5).
