Fix some bugs relating to the use of buffers
in the overlay frames.
Fix bug where a mid sequence overlay was
propagating large partition and transform sizes into
the subsequent frame because of :-
sf->last_partitioning_redo_frequency > 1 and
sf->tx_size_search_method == USE_LARGESTALL

This patch implements a mechanism for inserting a second
arf at the mid position of arf groups.
It is currently disabled by default using the flag multi_arf_enabled.
Results are currently down somewhat in initial testing if
multi-arf is enabled. Most of the loss is attributable to the
fact that code to preserve the previous golden frame
(in the arf buffer) in cases where we are coding an overlay
frame, is currently disabled in the multi-arf case.

The encoder currently allocates frame buffers before
it establishes what the chroma sub-sampling factor is,
always allocating based on the 4:4:4 format.
This patch detects the chroma format as early as
possible allowing the encoder to allocate buffers of
the correct size.
Future patches will change the encoder to allocate
frame buffers on demand to further reduce the memory
profile of the encoder and rationalize the buffer
management in the encoder and decoder.

This patch insures that the last byte of a chunk that contains a
valid superframe marker byte, actually has a proper superframe index.
If not it returns an error.
As part of doing that the file : vp90-2-15-fuzz-flicker.webm now fails
to decode properly and moves to the invalid file test from the test
vector suite.

When decoding in serial mode, there will be only
one FrameWorker doing decoding. When decoding in
parallel mode, there will be several FrameWorkers
doing decoding in parallel.

See: https://code.google.com/p/chromium/issues/detail?id=362697
The code properly catches an invalid stream but seg faults instead of
returning an error due to a buffer not having been initialized. This
code fixes that.

The test for this is in test vector code ( show existing frames will
fail ). I can't check it in disabled as I'm changing the generic
test code to do this:

This commit allows the key frame to search through more prediction
modes and more flexible block sizes. No speed change observed. The
coding performance for rtc set is improved by 1.7% for speed -5 and
3.0% for speed -6.

A superframe is a bunch of frames that bundled as one frame. It is mostly
used to combine one or more non-displayable frames and one displayable frame.
For frame parallel decoding, libvpx decoder will only support decoding one
normal frame or a super frame with superframe index.
If an application pass a superframe without superframe index or a chunk
of displayable frames without superframe index to libvpx decoder, libvpx
will not decode it in frame parallel mode. But libvpx decoder still could
decode it in serial mode.
