No bitstream change.

Removes unused filters and the code for the case of 2 switchable filters;
also changes the 8tap-smooth filter coefficients for integer shifts to be
interpolating to be consistent with the way it is implemented currently.

Implements ability to signal and decode frames that are
encoded using only intra coding modes. Only the decode
side has been implemented here.

A 32x32 transform should have no internal filtering (check c==4)

Change the argument of get_uv_tx_size() to be an MBMI pointer, so that the
correct column's MBMI can be passed to the function.

Do not allow the rd code to check compound modes if
a segment level reference frame is selected.

Fixes mvref issue.

Fixed point scaling factors are calculated once for each
reference frame by using integer division. Otherwise fixed point
scaling routines are used in all scaling calculations. This makes it
possible to calculate fixed point scaling factors on device driver
software and pass them to hardware and thus avoid division on hardware.

TODO:
 - Missing check for maximum frame dimensions
   (currently scaling uses 14 bits)
 - Missing check for maximum scaling ratio
   (upscaling 16:1, downscaling 2:1)

Problems:
 - Straightforward fixed point implementation can cause error +-1
   compared to integer division (i.e. in x_step_q4). Should only
   be an issue for frames larger than 16k.

Was always using sb_type of first column in a row of 8x8 units when
determining decoded block edges as a subcondition for loop filter
skipping.

It seems like I inverted the meaning of the contexts by accident?

Reduces TX_SIZE contexts to 2 for each kind. The code is
cleaner and there is hardly any performance difference with
more than two contexts.

Results: almost neutral

This commit enables boundary blocks properly tested over allowable
partition types.

For key frames everything is the same as before. For inter frames we try
to reference last/golden/altref frame size. If there is no match then the
actual size is encoded. Also we don't allow zero width and height anymore.

Use the current block's skip flag to determine edge skipping.

Made changes to the frame header to write the sync
code in the frame header for a non-displayable,
intra-only frame.

Extended reset_frame_context to 2-bits.

Adds coding of transform size within a frame by use of context
of transform sizes selected in left and above blocks.

Also incorporates code for generating stats.

TODO: generate and incorporate new default stats
