092b5bef37 abstract apply_temporal_filter
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.

should be propagated through to the corresponding output frame and
made available in the image's user_priv member. Fixes issue #252

b0da9b399d Add psnr/ssim tuning option
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.

2a87491fb0 Inform caller of decoder about updated references
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).

64baa8df2e Changed segmentation check order
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.

81cdeb7117 Adjusted breakout RD for SPLITMV
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.

08706a3ea7 Fix a bug in motion search code(2)
This fix added MV range checks for NEWMV mode as suggested by Jim.
To reduce unnecessary MV range checks, I tried Yaowu's suggestion.
Update UMV borders in NEWMV mode to also cover MV range check.
Also, in this way, every MV that is valid gets checked in diamond
search function.

The MV's range is 256. Since the new motion search uses a different
starting MV than the center ref MV, a MV range checking needs to
be done to avoid corruption.

Paul Wilkins
cec6a596b5 Change to inter_minq table.
The inter_minq table controls the range of quantizers available
for a particular frame in two pass relative to a max Q value.

The changes reduces the range somewhat. The effect of this
was a small increase (0.3% average) in psnr for the test set
but it should also help encode speed somewhat for higher
quality modes as it will reduce the number of iterations in the
recode loop.

The change damps the range of quantizers available locally
within a section of a clip and should therefore help keep quality
more uniform. If there is systematic overshoot or undershoot the
range can shift gradually to accommodate. However, there is
some increased risk of overshoot or undershoot against the target
bit rate in VBR mode and this risk will be more pronounced for short
clips.

c3bbb29164 Improve MV prediction accuracy to achieve performance gain
Add vp8_mv_pred() to better predict starting MV for NEWMV
mode in vp8_rd_pick_inter_mode(). Set different search
ranges according to MV prediction accuracy, which improves
encoder performance without hurting the quality. Also,
as Yaowu suggested, using diamond search result as full
search starting point and therefore adjusting(reducing)
full search range helps the performance.

9c8ad79fdc Set refresh_alt_ref_frame on keyframe encode.
On a keyframe alt ref and golden are refreshed.  The flag was
not being set and so on the frame after a keyframe, motion
search would occur on the alt ref frame.  This is not necessary
because the alt ref frame identical to the last frame in this
scenario.

Handle corner case where a forward alt-ref frame is put
directly after a keyframe.
