Amend and improve VP8 multithreading implementation
There are flaws in current implementation of VP8 multithreading encoder
and decoder as reported in the following issue:
https://code.google.com/p/chromium/issues/detail?id=158922
Although the data race warnings are harmless, and wouldn't cause real
problems while encoding and decoding videos, it is better to fix the
warnings so that VP8 code could pass the TSan test.
To synchronize the thread-shared data access and maintain the speed
(i.e. decoding speed), use multiple mutexes based on mb_rows to reduce
the number of synchronizations needed, make the reads and writes of
the shared data protected, and reduce the number of mb_col writes by
nsync times.
The decoder speed tests showed < 3% speed loss while using 2 ~ 4
threads.

In 32-bit build with --enable-shared, there is a lot of

reused.
This patch also fixes the HBD subpel variance tests that fail
when compiled without disable-optimizations.
These failures were caused by local variables in the assembler
routines colliding with the caller's stack frame.

Non-rd speed >=5: Include H/V intra for bsize=16x16.
H/V intra mode was only enabled for bsize < 16x16,
enable it also for bsize=16x16.
Metrics are neutral with this change:
Overall very small gain (0.1%), small visual gain on some RTC clips.

1 pass VBR mode bug fix.
(copied from VP9)
The one pass VBR mode selects a Q range based on a
moving average of recent Q values. This calculation
should have been excluding arf overlay frames as these
are usually coded at the highest allowed value. Their
inclusion skews the average and can cause it to drift
upwards even when the clip as a whole is undershooting.
As such it can undermine correct adaptation of the allowed
Q range especially for easy content.

Fix a enc/dec mismatch under CONFIG_MISC_FIXES
The culprit is on the decode side xd->lossless[i] setup was in wrong
location where segment features are not yet decoded.
Also on the encoder side, transform mode was not set consistently
between when tx_mode is selected and how tx_mode is enforced in
tx size selection.
