Silence signed/unsigned mismatch warnings by adding casts where
ts_number_layers does not match the sign of the variable to which
it is being compared.

This patch adds a buffer-based rate control for temporal layers,
under CBR mode.
Added vpx_temporal_scalable_patters.c encoder for testing temporal
layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).
Updated datarate unittest with tests for temporal layer rate-targeting.

This patch only works if the video is a width and height that are both
a multiple of 32.. It sets every partition to 16x16, and does INTRADC
only on the first frame and ZEROMV on every other frame. It always does
does the largest possible transform, and loop filter level is set to 4.
Was ~20% faster than speed -5 of vp8
Now 20% slower but adds motion search ( every block ), nearest, near
and zeromv
The SVC test was changed because - while this realtime mode produces
bad quality albeit quickly, it isn't obeying all the rules it should
about which frames are available.

vpx_codec_vp9x_cx is not used internally. Experimental flag from
vp9_extracfg is also not really used. YUV 4:4:4 just works after these
changes (you have to specify --profile=1 for the encoder).

SVC multiple layer per frame encoding is invoked with vpx_svc_init and
vpx_svc_encode. These interfaces are designed to be invoked from ffmpeg.
Additional improvements:
- make dummy frame handling a bit more explicit
- fixed bug with single layer encodes
- track individual frame sizes and psnrs instead of averages
- parameterized quantizer, 16th scalefactors, more logging,
- enabled single layer encodes to generate baseline
- include new mode for 3 layer I frame with 5 total layers

Warning was: "implicit conversion from enumeration type 'VPX_SCALING_MODE'
(aka 'enum vpx_scaling_mode_1d') to different enumeration type
'VPX_SCALING'".

set_active_map()
set_roi_map()
The APIs need be implemented and tested later, to insure consistency
with VP9 codec internals

This reverts commit a82001b1cfd688601bbda9b08b3d20e9b46b14d4, reversing
changes made to f6d870f7ae6f968bdbc342af80c8f71fa98f2ac2.
This commit breaks windows builds and needs some work to fix those and
some additional comments.

Adds modeled functions to decide the qp for altref frames in constant q
mode similar to other functions in use in bitrate mode.
Also turns on the constrained quality mode (end-usage=2) option which
was turned off before. Basic testing shows the mode works in principle,
to cap bitrate to the target-bitrate specified, while allowing lower
bitrate depending on the cq-level specified. The mode will need to be
improved over time.
Results for constant quality vs bitrate control mode:
derfraw300/fullderfraw: +3.0% at constant quality over bitrate control.
fullstdhdraw: +4.341%
stdhdraw250: +5.361%
