When building with --enable-daala_ec, the tx_type for intra blocks can be
 coded using the CDFs that are updated once per frame.
This patch converts a tx_type symbol to be coded with aom_write_symbol()
 and aom_read_symbol() that was missed in f3e8e267.

When the block has width/height above or equal to 64, use 16x16
block search step for reference motion vector search in the non-
immediate rows and columns.

Purpose:
-Reduce dynamic range of interpolation filter coefficents from 8
bits to 7 bits.
-Inner product for 8-bit input data can be stored in a 16-bit signed
integer.

Impact on compression efficiency:
-Marginal improvement, typically less than 0.5% BDR.

changes.

This allows the hardware decoder to start decoding ref_mv_idx
syntax prior to the sorting stage and hide the latency of entropy
decoding. The compression performance change is about 0.01% level.

av1_clpf_frame() was always called with the same src and dst,
so we only need one argument and the code supporting different
src and dst was removed.

The av1_mv_class0_tree is a balanced tree with two leafs and can
 simply be coded as a boolean with probability class0[0].
If CLASS0_SIZE is ever changed from 1, this change will need to be
 reverted.

Use in-place filtering, like in the decoder
(see eb5794da).

Change-Id: If037ead45f5cb3461347a63e0e415954d5dcba8b

Instead of having CLPF write to an entire new frame and
copy the result back into the original frame, make the
filter able to work in-place by keeping a buffer of size
frame_width*filter_block_size and delay the write-back
by one filter_block_size row.

This reduces the cycles spent in the filter to ~75%.

Signature of aom_read_xxx function changed recently:

So, updated the palette code to call those functions with the additional
parameter.

This patch adds bit account infrastructure to the bit reader API.
When configured with --enable-accounting, every bit reader API
function records the number of bits necessary to decoding a symbol.
Accounting symbol entries are collected in global accounting data
structure, that can be used to understand exactly where bits are
spent (http://aomanalyzer.org). The data structure is cleared and
reused each frame to reduce memory usage. When configured without
--enable-accounting, bit accounting does not incur any runtime
overhead.

All aom_read_xxx functions now have an additional string parameter
that specifies the symbol name. By default, the ACCT_STR macro is
used (which expands to __func__). For more precise accounting,
these should be replaced with more descriptive names.
