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.

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.

Now interp_kernel is obtained when it is really required (based on
mbmi->interp_filter value).

Fix that handles undefined CONFIG_SHARED

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.

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.

This commit slightly increases the bit allocation for key frame. This
improves speed -5 coding performance by 2.77% with aq-mode=0 and by
2.78% with aq-mode=3.

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.
