This avoids explicitly casting them to 'int' later.
These methods were already called with signed int arguments for pitch,
so this also avoids int -> unsigned int -> int conversion.

* changes:
  Remove speed feature of ext_interp experiment
  Refactor: handle_inter()

This prepares for the integration of rectangular transform size
into recursive transform block partition.

Make direct use of block_size_wide to fetch data for stride.

Support automatic scale for mapping between transform block size
and pixel block size.

Change-Id: I141b0477a85c0dcc5f99b4e5d880cfccfae6d316

Purpose:
-Reduce dynamic range of interpolation filter coefficents from 8
bits to 7 bits.
-Inner product for 8-bit input data can be stored in a 16-bit signed
integer.

Impact on compression efficiency:
-Marginal improvement, typically less than 0.5% BDR.

Change-Id: Ia09edf92bf9f7ecacc65c232ac6e656cde236634

Use table to replace the arithmetic computation for mapping between
transform block and pixel number. Support automatic scale of block
size and transform block size.

Avoid applying unary minus operator on unsigned type

- Eliminate the awkward _av1 suffix/infix in local variable names.
- Lift bitdepth selection out of the token loop.

The decoder is already linear so changing these tables would just create
a mismatch.

This change is similar to the one done for choose_tx_size_from_rd in
daf841b4

It gives a 4% speed-up on bus_cif.y4m with the following settings:
--cpu-used=4 -p 1 --end-usage=q --cq-level=40 --tile-columns=0 --tile-rows=0
