If show_existing_frame indicates that the decoder should
display an existing (previously decoded) frame, add a
check to make sure that the signaled buffer does contain
a valid decoded frame.

for ABSDATA mode, so segment loop filter level always fall in valid
range for both Absolute and delta modes.

The qindex for a segment was not clamped in ABSDATA mode, which may
cause invalid memory access if an ill-formed stream has a negative
value in ABSDATA mode. This commit added clamp to make sure qindex
for a segment always fall into valid range.

Skip coefficient cost update in non-RD mode decision setting. Allow
periodical mode and motion vector cost update. Currently every other
8 frames. The increment runtime is a constant number. Hence more
visible for CIF resolution, while negligible for 1080p.
Speed -6 compression performance for rtc set is improved by 4.5%.

This commit makes a refactoring of the rtc_use_partition. It allows
the encoder to take a preferred block size for non-RD mode decision.
The boundary blocks are handled such that smaller block sizes that
fit in the boundary size will be used instread.
In rtc mode, the coding performance of speed -6 for pedestrian_1080p
goes from
158980 b/f, 38.934 dB, 22721 ms to
159008 b/f, 40.064 dB, 23721 ms.
For rtc set, the speed -6 compression performance is improved by
26%. Still about 2dB behind speed -5 at this point.

- Update the vcxproj generator to pass the path to the batch file.
- Update the batch file the take the path to obj_int_extract.exe as arg
2.
Fixes this warning:
warning MSB8012: TargetPath does not match Linker's OutputFile property
value.

* Reduce the number of short cirtcuit checks by pre-computing and combining like checks.
* Postpone non-trivial initializations until after the shortcircuits are evaluated.
* Add some consts and const pointers.
No change to the actual results of the call or output of the encoder.

This commit enables the use of DC, vertical, and horizontal intra
prediction mode in rtc non-RD mode decision. When the best cost value
of inter modes is above a given threshold, the encoder runs the
above three intra modes and selects the one that has minimum
prediction residual in terms of SAD.
This together with recent changes on non-RD mode decision and coding
control improves compression performance of speed -6 by
derf 91%
yt 61%
hd 46%
stdhd 52%
In terms of encoding speed, it is about 3 times faster than speed -5.

When non-RD coding decision is used in rtc mode, the alt reference
is not used for inter frame prediction. This commit disabled alt ref
option whenever speed -6 is used.

Set TargetName for library builds instead of changing the value of
OutputFile.
This fixes the following warnings:
