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.

the quantizer is transmitted as 7-bits + sign so needs to be clamped in
the delta + absolute case.

This patch did a cleanup following the commit "Save NEON registers
in VP8 NEON functions". The pushing/poping of callee-saved NEON
registers was moved into individual NEON functions. Therefore,
we don't need to save those registers at the beginning of codec.
The related code was removed.

This commit added a check of reference frame to make sure that pre
buffer pointers are initialized only when necessary and make them
to 0 if ref frame is intra, hence those buffer should never be used.

The clamp operation may not affect the values of the final assigned mv
where compiler may make use of strict aliasing rule to optimize out the
clamp operation. This change made the code segments to better comply
the strict aliasing rule.

this was never fleshed out in the context of VP8, for which it was
added. for VP9 it has no meaning.

This allows code calling the library can choose an arbitrary
encryption algorithm.
Decoder control parameter VP8_SET_DECRYPT_KEY is renamed to
VP8D_SET_DECRYPTOR, and now takes an small config struct instead
of just a byte array.

Adding -Wshadow to CFLAGS generated a bunch of warnings. This patch
removes these warnings.

Writing all #define guards using the same style. Inlining macro
VP8DX_BOOL_DECODER_FILL into vp8dx_bool_decoder_fill. Removing unnecessary
includes.

Started adding support for multiple internal decoder instances. Also added
code to limit the vp8 config options available when using frame-based
multithreading.

When error concealment is enabled, it swaps the mi and prev_mi ptrs after
each frame is decoded. The postproc uses the mi ptr for the mode info context.
Now the postproc will use the correct mode info context.
