such that the code flow in encodemb.c can be simpler

This patch eliminates the copying of data when using FLIPADST forward
transforms, by incorporating the necessary data flipping into the
load_buffer_* functions of the SSE2 optimized forward transforms. The
load_buffer_* functions are normally inlined, so the overhead of copying
the data is removed and the overhead of flipping is minimized. Left to
right flipping is still not free, as the columns need to be shuffled in
registers.
To preserve identity between the C and SSE2 implementations, the
appropriate C implementations now also do the data flipping as part of
the transform, rather than relying on the caller for flipping the input.
Overall speedup is about 1.5-2% in encode on my tests. Note that these
are only the forward transforms. Inverse transforms to come in a later
patch.
There are also a few code hygiene changes:
- Fixed some indents of switch statements.
- DCT_DCT transform now always use vp10_fht* functions, which dispatch
to vpx_fdct* for DCT_DCT (some of them used to call vpx_fdct*
directly, some of them used to call vp10_fht*).

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

This commit fixes the merge conflicts between master and nextgenv2 and
disable early termination in choose_tx_size() to avoid failure in test.
The test failures are pre-existing, some of the issue were fixed in
masterbase already, so will have another merge to introduce the fixes.

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

This experiment allows using full above/right edges for all transform
sizes whenever available (for d45/d63), and adds bottom/left edges for
d207.
See issue 1043.

This commit makes the rate-distortion optimization for chroma
component support the recursive transform block coding scheme.

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

Add the row and column index to the argument list of unit functions
called by foreach_transformed_block wrapper. This avoids the
repeated internal parsing according to the block index.

Creates new hybrid transforms combining symmetric DST with
ADST and DCT. Thus a total of 16 transforms are supported.

Tested locally on several derf sequences, speed (encoder + decoder)
is slower by less than 1%.
It is part of the EXT_TX experiment, which is to be continued to
explore different transform variants.
