Urvang Joshi 526484482a Code cleanup: mainly rd_pick_partition and methods called from there. 
- Const correctness
- Refactoring
- Make variables local when possible etc
- Remove -Wcast-qual to allow explicitly casting away const.

Cherry-picked from aomedia/master: c27fcccc
And then a number of more const correctness changes to make sure other
experiments build OK.

Urvang Joshi b100db7c1d Wrap palette code inside CONFIG_PALETTE flag. 
This flag was already added to aomedia/master, so bringing it back to
webm/nextgenv2, as part of an effort to get the two codebases in sync.

Yue Chen 49587a77f1 Fix unit test failure for RECT_TX + VAR_TX 
Disable rect_tx because we only support 4x4 Walsh-Hadamard transform
in lossless mode.

Fixes failure in ./test_libaom --gtest_filter=*Large*ScreencastQ0/1
Configuration: --enable-experimental --enable-var-tx --enable-rect-tx
 --enable-ref-mv --enable-ext_intra --enable-ext_tx --enable-debug

Urvang Joshi cb586f3ba9 enums.h: Combine related #defines into packed enums. 
enums for BLOCK_SIZE, TX_SIZE and PREDICTION_MODE.

Note: These were converted to #defines earlier to save on memory:
https://chromium-review.googlesource.com/#/c/269854/

But we, instead, use attribute 'packed' (see here:
https://gcc.gnu.org/onlinedocs/gcc/Common-Type-Attributes.html#Common-Type-Attributes)
to ensure that these enums use the smallest possible integer type,
and so use smallest memory when used in structs/arrays etc.

this matches style guidelines and stabilizes successive runs of
clang-format across the tree. remaining types should be address in
successive commits.
