6cfaff95b7 Sync with aom branch for ext-refs 
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

(1) 780952 Add encoder first pass support to bi-prediction in EXT_REFS
(2) f91498 Add pred prob handling for new references in EXT_REFS
(3) e91472 Add decoder support for bi-direct prediction in EXT_REFS
(4) 0dbac9 Add encoder support to new references in EXT_REFS
(5) ad70cc Remove hard-coded number for EXT_REFS
(6) 9c1e2f Add the use of new reference frames at encoder in EXT_REFS
(7) 6d4fde Add the experiment flag of EXT_REFS

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.

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.
