ba8b5e8d6d Use separate inter predictors for enc/dec
The decoder will construct inter predictor using lazy border extension,
while the encoder, going with multiple runs of motion search in the rate-
distortion optimization loop for each block, does border extension at
frame level. This commit makes separate the inter predictors for encoder
and decoder, respectively.

86d2a9b978 Separate setup_scale_factor/extend_frame_borders
This commit takes out vp9_extend_frame_borders from
vp9_setup_scale_factors.

The refactoring is for the preparation of the use of lazy border
extension at decoder. This makes it necessary to handle border
extension separately at encoder/decoder. The use of
vp9_extend_frame_borders will be removed, when lazy border extension
is ready.

175c313a12 Improve scale_factors struct
The ref's scale_factors are set at frame level, and then copied for
each partition block. Since the struct members are mostly constant,
this patch separated the constant and non-constant members, and
reduced struct copying. This gave 0.5% ~ 1.4% decoder speed gain.

The only case where they were intentionally pointing to different
structures was in mbgraph, and this didn't have the expected behavior

9ec09700d6 Adding vp9_get_filter_kernel() function.
Moving INTERPOLATIONFILTERTYPE enum and subpix_fn_table struct to
vp9_filter.h. Adding convenient typedef for subpel kernels.

Function vp9_setup_interp_filters() besides setting xd->subpix.filter_x &
xd->subpix.filter_y has a side effect of also setting scale factors. This
is not required inside decode_modes_b() because scale factors have been
already set by set_ref() calls. That's why replacing
vp9_setup_interp_filters() call with newly created vp9_get_filter_kernel()
call. The behavior of vp9_setup_interp_filters() is unchanged (it
is used from the encoder).

ac6093d179 New mode_info_context storage -- undo revert
mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of pointers to MODE_INFO structs.  The
MODE_INFO structs are now stored as a stream (decoder only),
eliminating unnecessary copies and is a little more cache

dae17734ec New mode_info_context storage
mode_info_context was stored as a grid of MODE_INFO structs.
The grid now constists of a pointer to a MODE_INFO struct and
a "in the image" flag.  The MODE_INFO structs are now stored
as a stream, eliminating unnecessary copies and is a little
more cache friendly.

For the test clips used, the decoder performance improved
by ~4.3% (1080p) and ~9.7% (720p).

Patch Set 2: Re-encoded clips with latest. Now ~1.7% (1080p)
and 5.9% (720p).

5ebe503f04 Merge scale_factors and scale_factors_uv.
This prevents a duplicate memcpy of a 128-byte struct every time
set_scale_factors() is called (which is a lot), thus leading to a
decrease from 3.7 MB to 1.85 MB of struct copying per 64x64 block
RD/partition loop.

Overall, this decreases encoding time of the first 50 frames of bus
@ 1500kbps (speed 0) from 1min5.9 to 1min4.9, i.e. about a 1.5%
overall speedup. We can likely get more gains by removing the copy
of the other struct (and replacing it with an indexing) as well.

86bb6df005 Fixed point reference picture scaling
Fixed point scaling factors are calculated once for each
reference frame by using integer division. Otherwise fixed point
scaling routines are used in all scaling calculations. This makes it
possible to calculate fixed point scaling factors on device driver
software and pass them to hardware and thus avoid division on hardware.

TODO:
 - Missing check for maximum frame dimensions
   (currently scaling uses 14 bits)
 - Missing check for maximum scaling ratio
   (upscaling 16:1, downscaling 2:1)

Problems:
 - Straightforward fixed point implementation can cause error +-1
   compared to integer division (i.e. in x_step_q4). Should only
   be an issue for frames larger than 16k.

679e4abdd5 Initial version of alpha channel support
This is a mostly-working implementation of an extra channel in the
bitstream. Configure with --enable-alpha to test. Notable TODOs:

 - Add extra channel to all mismatch tests, PSNR, SSIM, etc
 - Configurable subsampling
 - Variable number of planes (currently always uses all 4)
 - Loop filtering
 - Per-plane lossless quantizer
 - ARNR support

This implementation just uses the same contents as the Y channel
for the A channel, due to lack of content and general pain in
playing back 4 channel content. A later patch will use the actual
alpha channel passed in from outside the codec.
