Since the size used with cfl_load can either be based on the transform block size and the prediction block size, width and height are used as parameters instead of TX_SIZE. This resolves a problem where cfl_compute_alpha_ind was reading uninitialized memory. Change-Id: I187dbdd5b2e8bd85e82bb77eb74859bee2cd3f1e

Even though number of unique colors in a block may be at least PALETTE_MIN_SIZE, sometimes the K-means can generate fewer than PALETTE_MIN_SIZE unique centroids due to integer rounding. This was resulting in "k - PALETTE_MIN_SIZE" being negative and using that as an index into palette_y_size_cost array was causing a UBSan error.

Adds a speed feature to control which references to use to compute global motion. Also adds logic to not compute duplicate sets of parameters when reference frames point to the same buffers. Includes some renaming of functions to set good speed features to make things clearer. Change-Id: I641d33441fde98af18cad8d4db49cf7d5d153ead

Use a simpler least-squares function for affine and rotzoom model estimation, instead of computing the pseudo inverse. Also refactors the code into a separate mathutils.h file. The SVD code is currently used only for estimation of the homography models which can be removed when we remove the homography models. Coding efficiency change is in noise range, with the small difference coming from numerical precision issues. Change-Id: I0a9eb79495911cea21a7945b397d596e22a2a186

Writes and reads alpha to and from the bitstream. A special case is needed on the encoder side to handle prediction block skips. Since whether or not a prediction block is skipped during CfL, a rollback is required if the block was skipped and the alpha index was not zero. The advantage of this is that no signaling is required when the prediction block is skipped as it is assumed tha the alpha index is zero. A encode facade is added to the intra prediction facade as CfL requires special encoder side operations. Change-Id: Ic3b11d0fdbd51389d862112eb09d8785127a6b06
