Account for the txb_optimize effect on level map context modeling
in the transform block rate distortion optimization search.
Properly update such information in the txb hash rd cost.

BUG=aomedia:1118

Previously the tx block order, i.e. the child index, was wrong for
rectangular partition blocks.

Re-eanbles tx rd hash for rectangular blocks, encoder speed up by 7%; no
compression quality loss.

Merged convolve_round experiment and removed its config flag in the code.
Removed compound_round code.

This unifies the coding of signed values in the uncompressed part,
and prevents having one coding for "minus zero".

Change-Id: I3bdc1ab23a33bec0d9a8fe98d5a6bf91df90ff15

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.

extrapolation situations.

'tx_size_sqr_map' in both code and test.

get_nz_map_ctx_from_stats() is take TX_CLASS instead of TX_TYPE, this
commit makes sure right type of parameter is passed in.

Make the motion field projection process independent of the
reference frame type syntax.

Change-Id: Ie5d024d76ddb990fe623c83b3f4b4b6fadc72d2c

The motion vector storage location in the reference frame is set
to be dependent on the relative frame position, instead of the
reference frame index.

3/4th of the coeffs and repack the 1/4th non-zeros.

At both callsites, the "rsi" parameter is the rst_info field from cm,
which is already passed.

Change-Id: I837ac655a03ebf0de6fbdaece4f4910f750e4898

This is done at the two call sites (where it's needed to avoid saving
lines unnecessarily for striped loop restoration context), so there's
no need to repeat it here.

This patch fixes up av1_tx_type_cost to match the code in
av1_write_tx_type. Beforehand, we wrongly assumed a 32x16 block needed
to signal its transform size (with rect-tx-ext & rect-tx-ext-intra)
because we were passing 16x16 to get_ext_tx_types.

I've also changed av1_write_tx_type to use get_min_tx_size rather than
inlining its body. No functional change, but it's probably better to
use the same helper function both times.

Make lpf_sb compatible with loopfilter_level, when USE_GUESS_LEVEL = 1.

Filter levels will be selected based on q index and applied for
filtering on Y, U, V planes separately.

Current model only allows to guess one filter level.
Now Y_vert = Y_horz = U = V. In the future, we need to retrain the
model and get filter levels for Y_vert, Y_horz, U and V separately.

When USE_GUESS_LEVEL = 0, lpf_sb can't work with loopfilter_level yet.
