Modified the resize unit test so that it optionally
writes the encoded bitstream to file. The macro
WRITE_COMPRESSED_STREAM should be set to 1 to enable
output of the test bitstream; it is set to 0 by default.

This commit reworked the unit test for 8x8 forward transform. It
allows scalability to cover various implemented versions.

The CpuSpeedTest is extended to cover 2pass good quality with CpuUsed
from 0 to 4. The BordersTest is changed to use CpuUsed 1 for faster
turn around.

Added the resize_test unit test to the VP9 set.
Set g_in_frames = 0 to avoid a problem when the total
number of frames being encoded is smaller than
g_in_frames. In this case the test will not have
access to the encoded frames and will not be able to
compare them for testing for encoder/decoder mismatch.

This commit completes the per coefficient accuracy check and memory
overflow check for SSE2 and other implemented versions of 16x16
transform.

This commit refactors the 16x16 transform unit test. It enables the
test on all implemented versions of forward and inverse 16x16 transform
modules.

This commit enabled a full functional test on 32x32 forward/inverse
transform, including round-trip error and memory overflow check. It
tests the prototype functions in C and all other implementations if
applicable.

There is another unit test that has been failing randomly on win32
build. Investigation has shown that the failure was caused by simd
register state is not reset appropriately in the fdct8x8 test. This
commit added ClearSystemState() in the teardown of this test, tests
showed it resolved the random failure issue for win32 build.

- Intermediate height was not correct i.e. when block size is 4 and
y_step_q4 is 6. In this case intermediate height was
(4*6) >> 4 = 1 and vertical interpolation needs two source pixels
plus 7 extra pixels for taps.
- Also if the current output block is 16x16 and we are using 4x upscaling
we need only 12 rows after horizontal filtering instead of 16.
Patch Set 2: Intermediate_height updated after CL 66723
"Fix bug in convolution functions (filter selection)"
Change-Id: I5a1a1bc2ac9d5edb3a6e0818de618bf318fdd589
(In response to Issue 604:
https://code.google.com/p/webm/issues/detail?id=604)
There were bugs in the convolution code for two cases:
1. Where the filter table was assumed to be aligned to a
256 byte boundary. The offset of the pixel in the
source buffer was computed incorrectly.
2. Where no such alignment assumption was made. An
incorrect address for the filter table base was used.
To fix both problems, I now assume that the filter table is
256-byte aligned and modify the pixel offset calculation to
match.
A later patch should remove the restriction that the filter
table is aligned to a 256-byte boundary.
There was also a bug in the ConvolveTest unit test
(convolve_test.cc).
(Bug & initial fix suggestion submitted by Tero Rintaluoma
and Sami Pietilä).

Currently, the best quality mode in VP9 is not very well developed,
and unnecessarily makes the encode too slow. Hence the command line
default is changed to "good" quality. Also, the number of passes
default is changed to 2 passes as well, since 1-pass encoding is
not very efficient in VP9.
Besides, a number of VP9 defaults are set to the currently
recommended settings. With these changes, vpxenc
run with --codec=vp9 --kf-max-dist=9999 --cpu-used=0 should
work about the same as our borg results.
Note when the --cpu-used=0 option is dropped there will be a slight
difference in the output, because of a difference in the cpu-used
value for the first pass. Specifically, the default when unspecified
is to use cpu_used=1 for the first pass and cpu_used=0 for the
second pass. But when specified, both passes will use the cpu-used
value specified.
Note that this also changes the default for VP8 as being "good"
but other options stay unchanged.

The mix use of double type and simd code caused invalid values stored
in double variables, further caused unit tests to fail. The failures
were only observed on x86-win32-vs9 build with vs2008.

Enable use_x86inc as a commandline option. Fix Bug with sse2 when
x86inc is disabled. Adds Sad asm protection to x86inc protection

Support enabling it or disabling it. Moved read out to configure.sh

Call the individually optimized horizontal and vertical functions. This
implementation abuses the temp buffer.
This will be replaced with a custom optimized function.
