If a block has all coefficients quantized to zero, the codec will
assume that it uses largest transform block size.

Allows inter and intra tx_types to have different sets of
transforms for different tx_size/sb_type combinations.

Some more testing of this patch would probably be useful, but I
think the basics of it should work fine now.
See issue 1035.

We only write EOSB tokens if we write tokens (i.e. not for skip blocks),
and we write EOSB tokens per-plane instead of per block.

This commit makes the transform, quantization, tokenization and
their corresponding inverse operations support recursive transform
block coding process.

This commit re-designs the bitstream syntax to support recursive
transform block partition. The initial stage targets the inter
prediction residuals.

We have historically added new bits to cat6 whenever we added a new
transform size (or bitdepth, for that matter). However, we have
always coded these new bits regardless of the actual transform size,
which means that for smaller transforms, we code bits that cannot
possibly be set. The coding (quality) impact of this is negligible,
but the bigger issue is that this allows creating bitstreams with
coefficient values that are nonsensible and can cause int overflows,
which then de facto become part of the bitstream spec. By not coding
these bits, we remove this possibility.
See issue 1065.

This commit removes mbmi_ext_base pointer from MACROBLOCK struct.
Its use case can be fully covered by cpi->mbmi_ext_base pointer.

Spatial/temporal svc code was removed. Verified using Borg test,
and the results before and after the change are matching.
