This reverts commit 79b78b7d.

The transform coefficient range needs some more tuning.
Before we finalize on that front, directly applying clamping
would cause multiple unit test failure issues. Hence revert
this Cl temporarily.

When --enable-coefficient-range-checking isn't specificed, clamp the
coefficient at each stage.

This doesn't change the decoder behaviour for existing AV1 streams.
However, some AV1 bitstreams that would have been rejected by the
decoder as illegal (range check failure) are now legal bitstreams.

There is no impact on video quality.

The highbd_clip_pixel_add() function is generalized to be used in
the regular 8 bit path. Move its defintions outside the highbd
experimental flag.

This resolves the comiler warning in unit tests when high bit-depth
is turned off.

Thanks to Luc Trudeau for the report and Alex Converse for the
suggestion on how to make the macro safe for all integer sizes.

The uncompressed frame header contains a bit to signal whether the
frame is encoded using 64x64 or 128x128 superblocks. This can vary
between any 2 frames.

vpxenc gained the --sb-size={64,128,dynamic} option, which allows the
configuration of the superblock size used (default is dynamic). 64/128
will force the encoder to always use the specified superblock size.
Dynamic would enable the encoder to choose the sb size for each
frame, but this is not implemented yet (dynamic does the same as 128
for now).

Constraints on tile sizes depend on the superblock size, the following
is a summary of the current bitstream syntax and semantics:

If both --enable-ext-tile is OFF and --enable-ext-partition is OFF:
     The tile coding in this case is the same as VP9. In particular,
     tiles have a minimum width of 256 pixels and a maximum width of
     4096 pixels. The tile width must be multiples of 64 pixels
     (except for the rightmost tile column). There can be a maximum
     of 64 tile columns and 4 tile rows.

If --enable-ext-tile is OFF and --enable-ext-partition is ON:
     Same constraints as above, except that tile width must be
     multiples of 128 pixels (except for the rightmost tile column).

There is no change in the bitstream syntax used for coding the tile
configuration if --enable-ext-tile is OFF.

If --enable-ext-tile is ON and --enable-ext-partition is ON:
     This is the new large scale tile coding configuration. The
     minimum/maximum tile width and height are 64/4096 pixels. Tile
     width and height must be multiples of 64 pixels. The uncompressed
     header contains two 6 bit fields that hold the tile width/heigh
     in units of 64 pixels. The maximum number of tile rows/columns
     is only limited by the maximum frame size of 65536x65536 pixels
     that can be coded in the bitstream. This yields a maximum of
     1024x1024 tile rows and columns (of 64x64 tiles in a 65536x65536
     frame).

If both --enable-ext-tile is ON and --enable-ext-partition is ON:
     Same applies as above, except that in the bitstream the 2 fields
     containing the tile width/height are in units of the superblock
     size, and the superblock size itself is also coded in the bitstream.
     If the uncompressed header signals the use of 64x64 superblocks,
     then the tile width/height fields are 6 bits wide and are in units
     of 64 pixels. If the uncompressed header signals the use of 128x128
     superblocks, then the tile width/height fields are 5 bits wide and
     are in units of 128 pixels.

The above is a summary of the bitstream. The user interface to vpxenc
(and the equivalent encoder API) behaves a follows:

If --enable-ext-tile is OFF:
     No change in the user interface. --tile-columns and --tile-rows
     specify the base 2 logarithm of the desired number of tile columns
     and tile rows. The actual number of tile rows and tile columns,
     and the particular tile width and tile height are computed by the
     codec ensuring all of the above constraints are respected.

If --enable-ext-tile is ON, but --enable-ext-partition is OFF:
     No change in the user interface. --tile-columns and --tile-rows
     specify the WIDTH and HEIGHT of the tiles in unit of 64 pixels.
     The valid values are in the range [1, 64] (which corresponds to
     [64, 4096] pixels in increments of 64.

If both --enable-ext-tile is ON and --enable-ext-partition is ON:
     If --sb-size=64 (default):
         The user interface is the same as in the previous point.
         --tile-columns and --tile-rows specify tile WIDTH and HEIGHT,
         in units of 64 pixels, in the range [1, 64] (which corresponds
         to [64, 4096] pixels in increments of 64).
     If --sb-size=128 or --sb-size=dynamic:
         --tile-columns and --tile-rows specify tile WIDTH and HEIGHT,
         in units of 128 pixels in the range [1, 32] (which corresponds
         to [128, 4096] pixels in increments of 128).

If --enable-ext-partition is used at build time, the superblock size
(sometimes also referred to as coding unit (CU) size) is extended to
128x128 pixels.

Using this we can eliminate large numbers of calls to predict intra,
and is also faster than most of the variance functions it replaces.
This is an equivalence transform so coding performance is unaffected.

Encoder speedup is approx 7% when var_tx, super_tx and ext_tx are all
enabled.

It in essence refactors the code for both the interpolation
filtering and the convolution. This change includes the moving
of all the files as well as the changing of the code from vp9_
prefix to vpx_ prefix accordingly, for underneath architectures:
(1) x86;
(2) arm/neon; and
(3) mips/msa.
The work on mips/drsp2 will be done in a separate change list.

vp9_quantize_dc
