vpx_svc_parameters_t contains id, resolution and min/max qp for each spatial layer.

In this change we will use extra config to send min/max qp and scaling factors, then calculate layer resolution inside encoder.

Change from VP8E_SET_NOISE_SENSITIVITY to VP9E_SET_NOISE_SENSITIVITY

Change-Id: Ia210a7029b26924e30973f0f9798a338e0412407

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.

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.

In order to understand memory layout consider the declaration of the
following structs. The first one is a part of our API:

struct vpx_codec_ctx {
  // ...
  struct vpx_codec_priv *priv;
};

The second one is defined in vpx_codec_internal.h:

struct vpx_codec_priv {
  // ...
};

The following struct is defined 4 times for encoder/decoder VP8/VP9:

struct vpx_codec_alg_priv {
  struct vpx_codec_priv base;
  // ... 
};

Private data allocation for the given ctx:

struct vpx_codec_ctx *ctx = <get>
struct vpx_codec_alg_priv *alg_priv = <allocate>
ctx->priv = (struct vpx_codec_priv *)alg_priv;

The cast works because vpx_codec_alg_priv has a
vpx_codec_priv instance as a first member 'base'.

We don't output invisible frames with VP9.

Change-Id: I7b874d3ac454c1b2966d5d7d72e12a864b49afae

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.

This patch fixes slow first pass problem. Mode could only be determined
from the deadline value during frame encode call. Unfortunately, we use
mode value before any encode calls during the first pass encoding (see
set_speed_features() logic). The mode for the first pass must be different
from BEST to make first pass fast.

Framerate changes over time, VP9EncoderConfig supposed to have static
read-only data.

We had a very complicated way to initialize cpi->pass from
cfg->g_pass:
switch (cfg->g_pass) {
  case VPX_RC_ONE_PASS:
    oxcf->mode = ONE_PASS_GOOD;
    break;
  case VPX_RC_FIRST_PASS:
    oxcf->mode = TWO_PASS_FIRST;
    break;
  case VPX_RC_LAST_PASS:
    oxcf->mode = TWO_PASS_SECOND_BEST;
    break;
}

cpi->pass = get_pass(oxcf->mode).

Now pass is moved to VP9EncoderConfig and initialization is simple:
switch (cfg->g_pass) {
  case VPX_RC_ONE_PASS:
    oxcf->pass = 0;
    break;
  case VPX_RC_FIRST_PASS:
    oxcf->pass = 1;
    break;
  case VPX_RC_LAST_PASS:
    oxcf->pass = 2;
    break;
}

Replaced encoder and decoder functions to get a pointer
to a reference frame with a common function, vp9_get_ref_frame,
and simplified it.

All changes are for spatial svc only.
1. Enable encoding hidden frames in each layer and use alt reference idex to reference the hidden frame in each layer
2. Use golden reference idx for spatial reference
3. For those layers that don't have hidden frames (caused by lack of frame buffers), reference a hidden frame in lower layers
4. Add "auto-alt-refs" in svc options
