* changes:
Palette: Use inverse_color_order to find color index faster.
Rewrite some loops to avoid -Wunsafe-loop-optimizations warnings.
Remove some useless casts
Add compiler warning flag -Wextra and fix related warnings.
Declare some array sizes to be constants (known at compile time).
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.

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.

Plus a small code clean up. The experiment of EXT_REFS, compared against
the baseline, using Overall PSNR, now obtains a gain on lowres as:
Avg: -5.818; BDRate: -5.653
Compared against the previous EXT_REFS results on lowres, a tiny gain is
obtained as:
Avg: -0.047, BDRate: -0.063

The (new) ans experiment replaces the bool coder with uABS bools. The
'rans' experiment adds multisymbol coding.
This matches the setup in aom/master.

Code cleanup: mainly rd_pick_partition and methods called from there.
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.

These signals were in the uncompressed frame header (as a temporary
hack), which caused two problems:
* We don't want that header to be duplicated in the slice header
* It was necessary to signal the number of bits to transmit up front
However, the filter size can be 128x128 which is greater than the SB
size, and a decoder wouldn't be able to know whether to read a bit or
not until the final SB of that 128x128 block has been decoded
(depending on whether the 128x128 is all skip or not). Therefore the
signalling was changed for 128x128 blocks so that every top left SB of
a 128x128 filter block contains a signal regardless of whether the
block is all skip or not. Also, all the MB's of 128x128 block are
filtered even if they are skip MB's. This gives the signal a purpose
even when the 128x128 block is all skip, and it also gives a slight
coding gain as it leaves a way to filter skip blocks, which was
previously forbidden.
