The aom_write_bit() was not calling buf_uabs_write_bit() while the
 aom_read_bit() function was calling uabs_read_bit().

Change-Id: If98975341472988e8d809aa80a647d7a2531e21e

Calling aom_write_bit() and aom_read_bit() with --enable-daala_ec
 would call aom_write() and aom_read() with probability 128 which
 would ultimately call od_ec_enc_bits() and od_ec_dec_bits().
This refactors that code and makes the call explicit.

The RD_DEBUG experiment computes stats in the _record() functions which
 then proxy calls through to the actual bit writer.
The aom_write_bit_record() should proxy calls through to aom_write_bit()
 instead of aom_write() with probability 128.

TODO: The distortion function of Daala should be added
to complete the activity masking working.

Note that PVQ QM matrix (i.e. scaler for each band of
transform block) is calculated in decoder side as exactly same
way in encoder. In Daala, this matrix is written to bitstream
and decoder does not generate it.

Activity masking can be turned on by setting below flag as 1:

Also some fixes for compatibility of ext-intra and alt-intra.

Modifies the C fwd txfms to have correct scaling. Rectangular
transforms now are always implemented in a way that the samller
side is transformed first.

The SSE2 tests are temporarily disabled until the SSSE2 code
is modified to be consistent with the C code.

Also includes a fdct32 fix.

borgtest results show a slight improvement.

The parameters are optimized only on Y, so disable chrominance
filtering for now. Later we can extend the syntax to have
separate parameters for the chrominance, or optimize the
parameters jointly over luminance and chrominance components.

1. The ethread test can only be ran when both the encoder and decoder are

2. Modify the ethread speed test range to speed 0 to 3 for AV1.

A crash was reported while encoding >1080p file using best mode.
(aom issue 107 and issue 108). The cause was that the speed features
were initialized using good mode in AV1. The patch(commit f330ca)
disabled the upsampled reference usage only for good mode, but not for
best mode. So, for 1st key frame, the encoder incorrectly called
reset_use_upsampled_references() that caused the segfault.

The patch(commit e4e93b) disabled the upsampled reference usage for all
encoding modes and resolved the issue. This patch fixed issue 108 and
further made sure the upsampled references would be used correctly.
