a04ed0e8f3 fix sharpness bug and clean up
sharpness was not recalculated in vp8cx_pick_filter_level_fast

remove last_filter_type. all values are calculated, don't need to update
the lfi data when it changes.

always use cm->sharpness_level. the extra indirection was annoying.

don't track last frame_type or sharpness_level manually. frame type
only matters for motion search and sharpness_level is taken care of in
frame_init

move function declarations to their proper header

20bd1446c0 Preload reference area to an intermediate buffer in sub-pixel motion search
In sub-pixel motion search, the search range is small(+/- 3 pixels).
Preload whole search area from reference buffer into a 32-byte
aligned buffer. Then in search, load reference data from this buffer
instead. This keeps data in cache, and reduces the crossing cache-
line penalty. For tulip clip, tests on Intel Core2 Quad machine(linux)
showed encoder speed improvement:
  3.4%   at --rt --cpu-used =-4
  2.8%   at --rt --cpu-used =-3
  2.3%   at --rt --cpu-used =-2
  2.2%   at --rt --cpu-used =-1

Test on Atom notebook showed only 1.1% speed improvement(speed=-4).
Test on Xeon machine also showed less improvement, since unaligned
data access latency is greatly reduced in newer cores.

Next, I will apply similar idea to other 2 sub-pixel search functions
for encoding speed > 4.

Make this change exclusively for x86 platforms.

0453aca5af Mark ARM asm objects as allowing a non-executable stack.
This adds the magic .note.GNU-stack section at the end of each ARM
 asm file (when built with gas), indicating that a non-executable
 stack is allowed.
Without this section, the linker will assume the object requires an
 executable stack by default, forcing an executable stack for the
 entire program.

With this fix, the experimental branch now builds and encodes correctly
with the following two configure options respectively:
--enable-experimental --enable-t8x8
--enable-experimental

1c24eb2b7b fixed a number of problems caused by auto merges
The auto merge process pull and merge commits from public git or master
branch. These automerges while worked well most time, but has created
a few problems. This commit fixed several issues existed long before
the latest 8x8 transform commit.

7d1b37cdac Increase chrow row alignment to 16 bytes.
This is done by expanding luma row to 32-byte alignment, since
 there is currently a bunch of code that assumes that
 uv_stride == y_stride/2 (see, for example, vp8/common/postproc.c,
 common/reconinter.c, common/arm/neon/recon16x16mb_neon.asm,
 encoder/temporal_filter.c, and possibly others; I haven't done a
 full audit).
It also uses replaces the hardcoded border of 16 in a number of
 encoder buffers with VP8BORDERINPIXELS (currently 32), as the
 chroma rows start at an offset of border/2.
Together, these two changes have the nice advantage that simply
 dumping the frame memory as a contiguous blob produces a valid,
 if padded, image.

d98a5ed4dd Revert "Disable __longjmp_chk protection"
This reverts commit b73a3693e5.

This version of the check doesn't work with generic-gnu, and figuring
out the correct symbol version at configure time is probably more work
than this is worth. May revisit in the future.

a25f6a9c88 Moved vp8_encode_bool into boolhuff.h
allowing the compiler to inline this function.  For real-time
encodes, this gave a boost of 1% to 2.5%, depending on the

b5ea2fbc2c Improved 1-pass CBR rate control
This patch attempts to improve the handling of CBR streams with
respect to the short term buffering requirements. The "buffer level"
is changed to be an average over the rc buffer, rather than a long
running average. Overshoot is also tracked over the same interval
and the golden frame targets suppressed accordingly to correct for
overly aggressive boosting.

Testing shows that this is fairly consistently positive in one
metric or another -- some clips that show significant decreases
in quality have better buffering characteristics, others show
improvenents in both.
