In real-time speed 6, no partition search is done. The inter
prediction results got from picking mode can be reused in the
following encoding process. A speed feature reuse_inter_pred_sby
is added to only enable the resue in speed 6.

This patch doesn't change encoding result. RTC set tests showed
that the encoding speed gain is 2% - 5%.

A superframe is a bunch of frames that bundled as one frame. It is mostly
used to combine one or more non-displayable frames and one displayable frame.

For frame parallel decoding, libvpx decoder will only support decoding one
normal frame or a super frame with superframe index.

If an application pass a superframe without superframe index or a chunk
of displayable frames without superframe index to libvpx decoder, libvpx
will not decode it in frame parallel mode. But libvpx decoder still could
decode it in serial mode.

- Rename build_targets to build_framework
- Add functions for creating the vpx_config shim and obtaining
  preproc symbols.

Speed 6 uses small tx size, namely 8x8. max_intra_bsize needs to
be modified accordingly to ensure valid intra mode checking.
Borg test on RTC set showed an overall PSNR gain of 0.335% in speed
-6.

This also changes speed -5 encoding by allowing DC_PRED checking
for block32x32. Borg test on RTC set showed a slight PSNR gain of
0.145%, and no noticeable speed change.

This is the first step to rework the rate-distortion modeling used
in rtc coding mode. The overall goal is to make the modeling
customized for the statistics encountered in the rtc coding.

This commit makes encoder to perform rate-distortion modeling for
DC and AC coefficients separately. No speed changes observed.
The coding performance for pedestrian_area_1080p is largely
improved:

speed -5, from 79558 b/f, 37.871 dB -> 79598 b/f, 38.600 dB
speed -6, from 79515 b/f, 37.822 dB -> 79544 b/f, 38.130 dB

Overall performance for rtc set at speed -6 is improved by 0.67%.

strip trailing '/' from paths, this is later converted to '\' which
causes execution errors for obj_int_extract/yasm. vs10+ wasn't affected
by this issue, but make the same change for consistency.

gen_msvs_proj:
+ add missing '"' to obj_int_extract call
  unlike gen_msvs_vcproj, the block is duplicated
  missed in: 1e3d9b9e build/msvs: fix builds in source dirs with spaces

Add elog() to tools_common, and checks for the executable in each test.
