      This allows nightly tests to detect other failure. This experiment
      will be re-enabled by default once we fix the issue#1143.

      Correctly set the daala_tx_dst8 and daala_tx_dst32 experiment flags in
       both the configure and cmake build systems.
      By default daala_tx_dst8 is disabled and daala_tx_dst32 is enabled.

      HW simplifications for intra predicition.
      Changed from 256 points interpolation to 32 points.
      Changed values in dr_intra_derivative to be upscaled by 64
      instead of 256 and adjusted the angles to be more evenly
      spread out. Values are also kept within 10-bits.

      WIP: lv_map_multi: New experiment · 13892108
      Ola Hugosson authored
      This experiment modifies lv_map to make use of multi symbol.
      
      Replace the nz_map and coeff_base binary CDF with a new multi-symbol
      CDF of size 4. The new base_cdf indicates for each coeff if the level
      is 0, 1, 2 or >2. Two new special contexts are added to be used for the
      last coefficient (the EOB coeff). For the EOB coefficient we already know
      that it is non-zero. We use one context for DC EOB and one for AC EOB
      (this can potentially be refined more).
      
      The new symbol is read/written by special bitreader/bitwriter functions.
      Those functions reduce the probability precision from 15bit to 9bit before
      the invocation of the arithmetic coding engine.
      
      The adapted symbol count is significantly reduced by this experiment.
      E.g. for the I-frame of ducks_take_off at cq=12, the number of adapted symbols
      is reduced from 6.7M to 4.3M.
