Select prediction filter type in non-RD mode decision
This commit allows the non-RD mode decision flow to select
prediction filter type in NEWMV mode. It provides 8.14% compression
performance gains in both settings of AQ=0 and 3. The current speed
impact is about 5% to 10% slower.

High-level hooks for Profile 2 (10/12 bit)
Adds some high-level hooks for profile 2 before further
progress on the implementation.
According to the definitiion in this patch:
1. Profile 2 only supports 10 or 12 bit color but not 8
2. Profile 2 supports all color sampling modes: 444, 422 and 420,
and alpha plane.
3. Profile 3 is currently undefined.
Please consider the definition carefully and suggest modifications
to the definition as needed.

Fix decoder resolution change with tiles
There was a bug with the decoder that if you started the decoder
with more threads than the first frame had tile columns. Afterwards
tried to decode a frame with more tile columns than the first frame,
the decoder would hang. E.g. run vpxdec --threads=4. The first frame
had two tile columns, then the next key frame had 4 tile columns, the
decoder would hang. If you started with 4 tiles and switched to 2
tiles the decoder would be fine. The issue is that the worker the thread
loop is using is stale.
I added a test vector "vp90-2-14-resize-848x480-1280x720.webm" that
exhibited the bug.

Add constrained-copy partition to speed features.
Copy up to a certain bsize, otherwise set to a fixed bsize.
This helsp to reduce artifact near moving boundary caused by full partition
copy without checking motion of super-block.
This artifact can occur at speeds 3,4 in real-time mode.
Issue: https://code.google.com/p/webm/issues/detail?id=738.
ARF overlays now use the same rate correction factor as regular inter
frames, further testing would be needed to see if it makes sense to use
a completely separate rate correction factor for ARF overlays.

Set up early RD cost check for NEWMV in non-RD mode decision flow
This commit estimates the motion vector rate cost right after full
pixel motion search. It combines this and the mode cost and compares
the corresponding rate-distortion cost. If it is already above the
current best one, skip the rest sub-pixel motion search and modeling
process. For pedestrian_area 1080p at 4000 kpbs, the speed -5 runtime
goes down from 39425 ms -> 38399 ms.

Add shell scripts for verifying basic vpx{dec,enc} features.
Tests the basics (first confirms feature is available in vpx_config.h):
- VP8 decode (in IVF file).
- VP9 decode (in WebM file).
- VP8 encode (to IVF and WebM).
- VP9 encode (to IVF and WebM).
- VP9 lossless encode (to IVF, currently disabled due to failure).
- Pipe input (to vpxdec and vpxenc).
Test data path and path to vpx{dec,enc} have been parameterized. In
addition:
- Supports disabling tests (test names prefixed with DISABLED_ are not
run by default).
- Supports filtering tests.
vpxdec.sh: Tests vpxdec.
vpxenc.sh: Tests vpxenc.
tools_common.sh: Common test functions.

Reinstating the DISABLE_RC_LONG_TERM_MEM macro
Reinstates this macro and truns it on in order to avoid issues
due to some frames at the end starving in harder videos.
A more acceptable solution is in the works.

tools_common.h: (msvs) avoid redefining off_t
in some configurations MSVS will define _off_t / off_t in wchar.h; the
former is used locally while the latter is for compatibility. this
change overrides off_t as in the past and sets _OFF_T_DEFINED to prevent
a clash in types.
