This reverts commit 72ef1949.

The concept:

There's too much noise in source pixels for variance and at low bitrate
the reconstructed looks nothing like the source so we have problems
getting good partitionings with either.   This skirts the issue by using
a box blur scaled down version for variance calculations.  To compare
against source_var_ moved keyframe to be rd based like source_var.

This commit breaks the overly broad header files into more
targeted and smaller ones, to help better structure the system
layout.

Fixed an encoder crash. Set skip_txfm to 0 for cases that skip_txfm
isn't calculated. Put memcpy of skip_txfm at right place.

The functions b_width_log2 and b_height_log2 only do direct
table fetch. This commit unifies such use cases by using the
table directly and removes these functions.

Add comments on the use case of these definitions. Further reduce
the scope of header file in vp9_context_tree.h.

The coefficient range checking is enabled when configured with
--enable-debug --enable-coefficient-range-checking
for vpxdec to detect ill-formed input stream. This addresses the
problem raised by issue #792.

Also fixes a case of distortion becoming negative and messing
up the RDCOST computation.
