Remove all the special case 2-tap, 4-tap, 16x16, 8x8, etc filters,
and instead just use one 2D 6-tap 4x4 filter.

Change-Id: I9ec560fb5609d1a3160e9a3d8b396911073517a0

Always use 4x4 modes rather than special casing 2,4,16 blocks.

Change-Id: I0301da4b0ff1885d79c1ae07b084d2d9b7487f72

Removed all the special case intra prediction code for clarity.

Change-Id: I54c2435aedb2b5b00e668aa9e6d7c332af9cda3f

Use the simplified bool decoder from the bitstream guide, slightly
modified to prevent reading past the end of the buffer. Modified
the token decoder to use the normal bool decoder rather than
inlining its own.

Change-Id: Ic525e773e9f8331ba548a6505cc6d9e5372a5af0

Implemented the decoder shutdown call to deallocate buffers when the
codec is destroyed.

Change-Id: I6cd62f40f34e0db91fb7eb8cb673f5d9726fe192

spatial resampling now supported.

Change-Id: Ifd959072b76ac3f8eeed00a0fd25acdde036defe

Initial support for simple loopfilter and bilinear subpixel motion
interpolation. This adds support for VP8 profiles 1-3 to dixie.

Change-Id: I76d45cf9843f6f7473783b7932af94f033eb6e82

When reallocating the framebuffer storage, clear references to the
freed memory to prevent it from being accessed.

Change-Id: Ib496b06be469328e8e269f905dc4c9cb6d453a27

The copy_{gf,arf} flags should copy the LAST buffer to the specified
buffer. The refresh_{gf,arf} flags should copy the CURRENT buffer to
the specified buffer.

Missed incrementing the pointer, so only the first segment would be
populated.

Cut and paste error caused UV delta Qs to overwrite Y1 DC delta Q.

This patch adds basic reconstruction for inter-predicted frames. It does
not properly handle clamping at the MV border.

Change-Id: Ib7e4395519aab0661a38f4e0f66972b5f08805cb

This is the more naive implementation as described in the bitstream guide,
rather than the masking version implemented in the reference code. However,
the core function prototypes were left as-is to make it easy to plug in the
reference assembly code.

Verified loopfiltered output matches reference decoder for 500 frames.

Change-Id: Ib4f197e864f07dbb918b6d5e742c6110d57c1f40

Verified reconstructed (but not loopfiltered) output matches reference
decoder for 500 frames.

This commit adds prediction functions for all the intra modes.

Scales as O(number-of-tokens) rather than O(16).

Incorporate the VP8DX_BOOL_DECODER_FILL macro, which is referenced by
the token decoder.

The "dixie" project will be a rewrite of much of the VP8 decoder core.
Some of the goals are:

  * Increase speed by paying more attention to data locality and
    cache layout, and by eliminating redundant work in general.

  * A different approach to multithreading, to treat all threads as
    equal and working on larger work units than a single MB.

  * Expose more of the bitstream to the application, essentially
    creating a vp8 parser utility. This could be useful for analyzing
    the complexity of a stream, to help set conformance points.

  * If the above goals are met successfully, replace the reference
    decoder.

For those interested in the etymology of the term "dixie:"
  decoder2 -> dx2 -> dxii -> dixie

1. Unavailability of each reference frame type should be tested
independently,
2. Also, only the VP8_GOLD_FLAG needs to be tested before setting
golden frame specific thresholds, and only VP8_ALT_FLAG needs
testing before setting thresholds relevant to the AltRef frame.

Since the intent is
to reset the appropriate bit in ref_frame_flags not to
test a logic condition. Prior result would always have
been ref_frame_flags being set to 0.
