Delta quant doesn't make sense if the intent is to encode
the frame in lossless mode.

Use c functions for 2x2 transform block quantization. This fixes
the enc/dec mismatch issue in cb4x4 mode when high bit-depth is
turned on.

Also make sure that qindex is clipped to the quantizer range.

Previously, we assumed that av1_init_plane_quantizers is always called with
segment_id == xd->mi[0]->mbmi.segment_id (and use the latter to derive the value
of 'qindex' to use in the quantizer). But this is no longer true when supertx
is enabled. This patch instead remembers the value of 'qindex' derived from
the latest call to av1_init_plane_quantizers and uses that directly.

From code only part of nextgenv2 (and not aomedia)

Change-Id: I21f7478a59d525dff23747efe5238ded16b743d2

- Change struct name to all caps SCAN_ORDER to be locally consistent.
- Rename struct pointers to 'scan_order' instead of hard to read short
  names 'so' and 'sc'.

Refactor to streamline the number of profiles needed, in
preparation for the next steps.

This commit changes to use int instead of unsigned for a variable used in
inverse quantization.

Change-Id: I8f0ff5f80c9e68d52425265ef177357c65ead1e2

The values after right shifts should fit into 32bit int. The commit
fixes MSVC build warning when new-quant is enabled.

This commit combines uniform quantizer with trellis based coefficient
level optimization. It improves the codebase compression performance:

lowres 0.8%
midres 1.0%
hdres  1.6%

Note that the current trellis optimization unit is using C code. This
will make the cost of the overall quantization process slower. A number
of optimizations will come up next.

This experiment implements non-uniform quantization where
the width of the bins increases gradually to more closely
match a laplacian distribution of the coeficcients.

Performance Gain:
derflr: 0.15%
hevcmr: 0.675%
