Parse the recursive transform block partition to fetch the actual
transform size. Use this correct transform size to select the
corresponding loop filter kernel. This slightly improves the coding
performance of recursive transform partition for hdres to 0.14%.

Also:
- For unsigned ints, don't check value >= 0 as that is always true.
- Add "-Wlogical-op" warning flag which would have warned that "logical
'or' of collectively exhaustive tests is always true" before this
patch.

Making this change in case the future implementation changes and the
compairson is no longer between single bits.

This ensures TGs can be decoded even if the whole
frame has not been received and the frame length
is not known.

For compound mode, it is a sure thing that one of the 2 reference frames
would be either a forward predictive reference, or a backward predictive
reference, and the other would provide a different prediction.

This is a manual adaptation of the following commit from aom/master:
ce12003d60
The original commit message:
A tile group is a set of tiles in scan order.
Each tile group has a version of uncompressed and compressed headers,
identical apart from tile group parameters.
Encoding probability updates takes account of the number of
headers to control overheads.
The decoder supports arbitrary numbers of tile groups with
arbitrary number of tiles. The number of tiles in a TG is
signalled in the uncompressed header for that TG.
The encoder currently only supports a fixed number
of TGs (3, when error resilient mode is on) of equal size
(except possibly for the last one).
The average BDR performnce with 3 tile groups versus
anchor with error resilient mode and up to 16 tiles is:
NR YCbCr: 3.02% 3.04% 3.05%
PSNRHVS: 3.09%
SSIM: 3.06%
MSSSIM: 3.05%
CIEDE2000: 3.04%

For clarity, use separate variables for 'color_ctx_hash' and
'color_ctx' instead of reusing same variables for both.

Use unified transform block size and coding block size map. This
prepares for the integration of 2x2 transform block size and the
rectangular transform block size.

Unify coefficient context used by different experiments. Make
block size and transform block size consistent with rest codebase.

Use the transform block partition depth counts to decide if to
reset the tx_mode at frame header level. Add a comment to make this
explicit.
