380cb1a93c Update uv_mode_cdf tables once per frame.

 computing them only when the probabilities are updated.

45ea963f0b Code class0 using aom_read() / aom_write().
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.

72762a2827 Use intra_ext_tx_cdf when coding tx_type.
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.

6048d05225 Bit accounting.
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.

454280dabf Fix warnings reported by -Wshadow: Part2: av1 directory
While we are at it:
- Rename some variables to more meaningful names
- Reuse some common consts from a header instead of redefining them.

d7fa8542f6 Read mode to mi->bmi for sub 8x8 blocks
Previously, only the motion vectors were being stored. This caused
a mismatch in the global motion experiment, which needs this
mode information to decide whether or not to use the gm parameters
in reconstruction.

e529986568 Add global motion experiment to rdopt
This patch completes the global motion experiment
implementation. It modifies the format of the motion
parameters to use the mv union to facilitate faster
copying and checks for parameters equal to 0 that occur
frequently in rdopt. The rd decisions for the global motion experiment
have also been added to rdopt.
