The original pruning function was not taking into account
that certain tx sizes/block sizes use a reduced tx set.

Prune 2: -0.48% perfomance drop, 30% speedup on foreman video

This patch changes the encoder only for the ext-refs experiment. For
each newly coded frame to refresh the LAST_FRAME, the decoder is
notified that the LAST4_FRAME is to be refreshed, and read out the
updated reference frame buffer vitural indexes for the next coded
frame in a way that:
LAST4_FRAME => LAST_FRAME,
LAST_FRAME  => LAST2_FRAME,
LAST2_FRAME => LAST3_FRAME, and
LAST3_FRAME => LAST4_FRAME.

Compared against the original ext-refs experiment in TOT, a small gain
is achieved in overall PSNR:
lowres Avg: -0.154
lowres BDRate: -0.044

The word 'pick' is usually used in functions that make decisions where
the bitstream allows multiple legal choices, and not to limit the
bitstream format itself.

This experiment will implement the use of a backward prediction
reference without temporal filtering. No overlay frame will be
transmitted, instead, the flag of show_existing_frame will be turned
on.

The encoder signals the interp filter type in the frame header if all
blocks use the same filter (see bitstream.c:fix_interp_filter). This
decision is made based on the counts, but with ext-interp, the counts
are actually only incremented for blocks that fail vp10_is_interp_needed
(see for example encodeframe.c:update_state), otherwise a default value
is used (EIGHTTAP_REGULAR). The decoder however first checks if the
interp filter is signaled at the frame level, and uses that filter type
for all blocks, even if the default value should have been used.

This patch makes the decoder first check with vp10_is_interp_needed
to see if the default value should be used and then checks the frame
level signaling, which reconciles the difference between encoder and
decoder.

The test used to test that multi-threaded encode/decode resulted in
the same reconstructed image as single-threaded encode/decode. This
however did not mean that the multi-threaded encoder produced the same
bitstream as the single-threaded encoder, as the multi-threaded encoder
could use different forward probability updates and still produce a
bitstream that is sub optimal but yields the same reconstructed image.
The test now asserts that the bitstream is the same as well as the
reconstructed image. Also added more cpu-use values for testing VP10.

Factor out common codes from vp10_get_pred_context_intra_interp().
This prevents a potential invalid access of pointers xd->left_mbmi
and xd->above_mbmi.

The coding statistics are identical.
