Happens in real-time mode. Will happen in good quality, speed 1.

Scott pointed out that last_frame_type only gets updated while
loopfilter exists. Since last_frame_type is also needed in
motion search now, it needs to be updated every frame.

Use the fast quantizer for inter mode selection and the
regular quantizer for the rest of the encode for good quality,
speed 1. Both performance and quality were improved. The
quality gains will make up for the quality loss mentioned in
I9dc089007ca08129fb6c11fe7692777ebb8647b0.

1. Search for block8x16/block16x8 uses block8x8's search results.
2. Check block4x4 only if block8x8 is chosen. (This hurts quality,
which will be improved in another check-in.)
3. In block4x4 search, the previous block's result is used as
MV predictor for next block.
This change improves performance.

Re-calibrated sad_per_bit16 and sad_per_bit4 tables to linearly
correlated to quantizer values, these two variables are used in
motion search for costing motion vectors. This change has an small
positive effect on compression.

stats_close() was not freeing memory for
single pass runs. It now takes in arg_passes
to determine when it should free memory.

Native Windows targets should use CV8 format debugging symbols, not
DWARF.

the lookup table is based on floating point calculations (see source)
by moving the *3 before the downshift and adding the rounding bit, the
delta (LUT - integer) goes from:
______________________________________
__ 1__ 1______________________________
__ 1__ 1______________________________
____ 1______ 1________________________
____ 1 2__ 2 1________________________
______ 1 1 2__ 2__ 2__ 2 1 1__________
________ 1 1 2 2__ 1 2 3 1 2__ 2__ 2__
to:
__-1__-1______________________________
______________________________________
____-1______-1________________________
______________________________________
________-1______________-1____________
______________________________________
it's important to be able to use the integer version because the LUT
more or less precludes SIMD optimizations

allow for optimized versions of apply_temporal_filter
(now vp8_apply_temporal_filter_c)
the function was previously declared as static and appears to have been
inlined. with this change, that's no longer possible. performance takes
a small hit.
the declaration for vp8_cx_temp_filter_c was moved to onyx_if.c because
of a circular dependency. for rtcd, temporal_filter.h holds the
definition for the rtcd table, so it needs to be included by onyx_int.h.
however, onyx_int.h holds the definition for VP8_COMP which is needed
for the function prototype. blah.

The pointer passed in the user_priv argument to vpx_codec_decode()
should be propagated through to the corresponding output frame and
made available in the image's user_priv member. Fixes issue #252

Add a new encoder control, VP8E_SET_TUNING, to allow the application
to inform the encoder that the material will benefit from certain
tuning. Expose this control as the --tune option to vpxenc. The args
helper is expanded to support enumerated arguments by name or value.
Two tunings are provided by this patch, PSNR (default) and SSIM.
Activity masking is made dependent on setting --tune=ssim, as the
current implementation hurts speed (10%) and PSNR (2.7% avg,
10% peak) too much for it to be a default yet.

Inform the caller of the decoder if a decoded frame updated last,
golden, or altref frames, required for realtime communication
proposed in document VP8 RTP payload format.
Added a new vpx_codec_control called VP8D_GET_LAST_REF_UPDATES, to be
called after vpx_codec_decode. The control will indicate which of the
reference frames that were updated by setting the 3 LSBs in the input
int (pointer).

In SPLITMV, the 8x8 segment will be checked first. If the 8x8 rd
is better than the best, we check the other segments. Otherwise
bail. Adjustments to the thresh_mult were necessary to make
up for the initial quality loss.
The performance improved by 20% (average) for good quality,
speed 0 and speed 1, while the overall quality remained the same.

vp8_rd_pick_best_mbsegmentation looks at y only. The new
breakout does not include the frame cost, the prob_skip_false
cost, or the uv rate. Performance improved by a few percent
and the quality remained the same.
