Clean up and simplification of both estimate_max_q
variants and only call once per clip/section.

This leads to a more constrained range of Q values
across a clip / section.

Average gains across all 4 test sets:-

PSNR ~0.5%  SSIM ~0.3%

For VP9, lossless coding is enabled by passing 0 for both min_q and
max_q. This is a valid configuration, and should not be warned.

Use the pre-fetched stride value.

In lossless coding, distortion is always 0. Early exit based on this
metric was incorrect.

This CL also changed to use best_rd instead of distortion as the metric
for easly exit as requested by Jim.

Add a full range motion search for regular block sizes. This runs
exhaustive search within the given reference area. This commit further
optimizes the search process by combining 4 points test into one
pipeline, which gives 30% speed-up as compared to run each individual
point at a time.

This full range search serves as a best possible motion search reference.
When replacing the diamond search with full range search, the speed 0
runtime of bus CIF at 2000 kbps goes from 153872ms to 623051ms. The
compression performance compared to speed 0 setting gains 0.585% for
derf set.

Removed an adaptive rate correction factor that was having
a negative impact on quality in many clips. This factor
was influencing the Q range available to each frame
independently of the bits allocated to each.
