Commit db5057c7 introduced a bug in that the active_worst_quality
selected by the 2 pass rate controller was being overridden for key
frames, causing a severe quality loss.

vp8_fast_quantize_b_neon function updated and further optimized.
 - match current C implementation of fast quantizer
 - updated to use asm_enc_offsets for structure members
 - updated ads2gas scripts to handle alignment issues

The existing emulation of posix semaphores on Windows uses SetEvent()
and WaitForSingleObject(), which implements a binary semaphore, not a
counting semaphore as implemented by posix. This causes deadlock when
used with the expected posix semantics. Instead, this patch uses the
CreateSemaphore() and ReleaseSemaphore() calls (introduced in Windows
2000) which have the expected behavior.

This patch also reverts commit eb16f00c, which split a semaphore that
was being used with counting semantics into two binary semaphores.
That commit is unnecessary with corrected emulation.

This patch is to fix a rare hang in multi-thread encoder that was
only seen on Windows. Thanks for John's help in debugging the
problem. More test is needed.

Changed 8-neighbor searching to 4-neighour searching, and continued
searching until the center point is the best match.

Test on test set showed 1.3% encoding speed improvement as well as
0.1% PSNR and SSIM improvement at speed=-5 (rt mode).

Will continue to improve it.

The commit also removed the slow ssim calculation that uses a 7x7
kernel, and revised the comments to better describe how sample ssim
values are computed and averaged

Always use CFLAGS/LDFLAGS that point to headers and libvpx.a inside our
build tree before ones from the environment, which could reference
headers or libs outside the build tree.

This fixes issue 307.

Thanks Jason for pointing that out on #vp8. ;-).

The skip flag is never set by the encoder for SPLITMV.

Fixes issue #323

Insertion sort performs better for sorting small arrays. In real-
time encoding (speed=-5), test on test set showed 1.7% performance
gain with 0% PSNR change in average.

This change simply exercises the VP8D_GET_FRAME_CORRUPTED control,
outputting a warning message at the end if the bit was set for any
frames. Should never produce any output for good input.

The end-of-buffer check is hoisted out of the inner loop. Gives
about 0.5% improvement on x86_64.

Allow more reliable detection of truncated bitstreams by being more
precise with the count of "virtual" bits in the value buffer.
Specifically, the VP8_LOTS_OF_BITS value is accumulated into count,
rather than being assigned, which was losing the prior value,
increasing the required tolerance when testing for the error condition.

Combine calc_iframe_target_size, previously only used for forced
keyframes, with calc_auto_iframe_target_size, which handled most
keyframes.

Change-Id: I227051361cf46727caa5cd2b155752d2c9789364

This is a first step in cleaning up the redundancies between
vp8_calc_{auto_,}iframe_target_size. The pick_frame_size() function is
moved to ratectrl.c, and made to be the primary interface. This means
that the various calc_*_target_size functions can be made private.
