'ref_frame_map' is initialized to -1. avoids using an invalid index if
VP9_GET_REFERENCE/VP8_COPY_REFERENCE controls are issued after a decode
error.

This commit enables encoder to select fast forward transform and
quantization path according to the prediction residual sse/variance,
in the rate-distortion optimization scheme.

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.

in the sub_pixel_*variance* function the dst is aligned to 16 bytes and not
to 32 bytes - now load unaligned data

Fix the interaction between active map and reuse_inter_pred_sby. The
reuse_inter_pred_sby feature expects inter predictors to already be
built, but blocks with active map on skip this step.

in the function sad32x32x4d and sad64x64x4d the source is aligned to 16 bytes
and not to 32 bytes - the load is now unaligned.

Specifies the bit-depth, color sampling and colorspace
for intra only frames for profiles > 0
Also adds checks to ensure that profile 1 and 3 are
exclusively used for non 420 streams.

This commit adds a configure time option used to enable strict error
checking in decoder to make sure intermediate stage cofficients of
inverse transforms are within valid range of signed 16 bit integer.
For valid VP9 input streams, intermediate stage coefficients should
always stay within the range of a signed 16 bit integer. Coefficients
can go out of this range for invalid/corrupt VP9 streams. However,
strictly checking this range for every intermediate coefficient can
be a burden for decoder, therefore such validation is only enabled
with configure option --enable-coefficient-range-checking.

This commit integrates the fast transform and quantization process
into skip_recode scheme in the rate-distortion optimization loop.
Previously the fast transform and quantization process was only
enabled for non-RD coding flow.
