1. This is to align with the ffmpeg implementation
2. Remove APIs for setting quantizers and scale-factors

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 various high bitdepth transform functions and tests.
Much of the changes are related to using typedefs tran_low_t
and tran_high_t for the final transform cofficients and intermediate
stages of the transform computation respectively rather than fixed
types int16_t/int. When vp9_highbitdepth configure flag is off,
these map tp int16_t/int32_t, but when the flag is on, they map
to int32_t/int64_t to make space for needed extra precision.

If optimizations use more than one cpu feature, allow
specifying them so that '--disable-X' still works

1. svc_encodeframe.c will not handle frame or stats packets anymore.
The app will process them.
2. Remove APIs that related to these packets.

don't bother decoding any further after receiving an earlier decode
error until a key/intra-only frame is encountered.

allocations within vp9_alloc_context_buffers() rely on mi_rows/mi_cols
individually, use those to determine whether to realloc rather than
stride and stride * rows. this fixes a crash with some fuzzed files for
invalid accesses into last_frame_seg_map and above_context.

proceeding using a corrupt (incompletely decoded) frame reference may
lead to incorrect assumptions about allocation sizes leading to a crash.

vp8_build_intra_predictors_mbuv_s().
This patch replaces the assembly version with an intrinsic
version.
On a Nexus 7, vpxenc (in realtime mode, speed -12)
reported a performance improvement of ~2.6%.

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.

It's built based on current spatial svc code.
We only support one spatial two temporal layers at this time.

attempting to decode a frame after the previous frame failed has the
potential of interrupting an earlier loop filter task

if the first frame was corrupt and loop filter not called, the next call
would assume the necessary allocations had been done and segfault when
accessing a NULL pointer

We can use one frame context for each layer so that we don't have
to reset the probs every frame. But we can't use prev_mi since we
may drop enhancement layers. So we have to generate a non vp9
compatible bitstream and modify it in the player.
1. We need to code all frames as invisible frame to let prev_mi
not to be used. But in the bitstream we need to code the
show_frame flag to 1 so that the publisher will know it's
supposed to be a visible frame.
2. In the player we need to change the show_frame flag to 0 for
all frames. Then add an one byte frame into the super frame
to tell the decoder which layer we want to show.
