Libvpx was memseting every external frame buffer before decode. This
was to work around a valgrind issue in our C loop filter. Most of
the time this was not needed and we have noticed some significant
performance loss on some platforms. Now we require the application to
zero out the buffers if it is using external frame buffers.

Adds config parameter vp9_highbitdepth, to support highbitdepth profiles.
Also includes most vpx level high bit-depth functions. However
encode/decode in the highbitdepth profiles will not work until
the rest of the code is in place.

Reinstates an assignment to prevent an asan failurere on google3.
Not sure why the failure happens. This was removed in a recent patch

Change-Id: Ifd9ccffd4c2164f4de38b21821ffb28bd779b0f3
Adds support for raw yuv inputs in 422/444 sampling for use
in profiles 1 and 3.
New options added to vpxenc are:
--i422 and --i444, which are to be used in conjunction with
--width, --height, and --fps for proper raw yuv handling.
A new option is added to vpxdec:
--rawvideo, which enforces raw yuv video output for the
bit-stream decoded irrespective of 420, 422 or 444 sampling.
The existing options --i420 and --yv12
are specialized for use only for 420 content.

Sets the bit-depth field as default 8 in the image structure in vp8.
Generalizes yuv read in preparation for support for reading 422/444
for 8-bit and 10/12-bit.

The y4m extension used is the same as the one used in ffmpeg/x264.
The patch is adapted from the highbitdepth branch.
Also adds unit tests for y4m header parsing and md5 check
of the raw frame data, as well as y4m writing.

Adding a --(enable|disable)-webm-io flag to control WebM container input and
output support. For now, enabling WebM IO by default only when there is a C++
compiler. Doing so because eventually we will move WebM IO to libwebm and it
is built using C++.

Added support for external frame buffers to libvpx's VP9 decoder.
If the external frame buffer functions are set then libvpx will
call the get function whenever it needs a new frame buffer to
decode a frame into. And it will call the release function
whenever there are no more references to that buffer.

File type check inside ivf_read_frame() is not necessary (it is done
before this function get called).
