Not all segment feature data elements are full-range powers of two, so
there are values that can be encoded that are invalid. Add a new function
to clamp values to the maximum allowed.

Support for gyp which doesn't support multiple objects in the same
static library having the same basename.

Don't use the switch to gf_rate_correction factor when
temporal layers is used (i.e., cpi->oxcf.number_of_layers > 1).
In temporal layers, we prefer to avoid this as any frame
(e.g., base layer frame at anchor of pattern) may update
both last and golden (and possibly alt-ref), and so we would get
different rate correction factors within the same layer.
This change will make sure one rate correction factor exists for each layer.
Also, made some other code in qp-regulate that depends on
alt/golden update specific to the 1 layer case.

Modified the mv_pred() fuunction that chooses a centre
point from which to start step searches to use the top
candidate vectors chosen previously.
Some gains (mainly on HD and tested with SB off).
Std_hd 0.874%, YT-hd 0.174%, YT 0.05%, Derf 0.036%

Vp9_sad3x16_sse2() is heavily called in decoder, in which the
unaligned reads consume lots of cpu cycles. When CONFIG_SUBPELREFMV
is off, the unaligned offset is 1. In this situation,
we can adjust the src_ptr to be 4-byte aligned, and then do the
aligned reads. This reduced the reading time significantly. Tests
on 1080p clip showed over 2% decoder performance gain with
CONFIG_SUBPELREFM off.

Add a new function vp9_decode_mb_tokens() that handles the switch
between different per-tx-size detokenize functions. Make actual
implementations (vp9_decode_mb_tokens_NxN()) static.

Don't declare variables if they only ever have a single value and are
used only as argument to another function call; instead, just hardcode
the value in the function call directly. Split out UV and Y coefficient
loops for clarity. Use xd->block[].qcoeff instead of xd->qcoeff + magic
to remove use of magic offset variables.

Don't declare variables if they only ever have a single value and are
used only as argument to another function call; instead, just hardcode
the value in the function call directly. Also remove unneeded brackets
around a code block, and remove the magic offsets 64 and 256 for chroma
values in the coefficient memory block.

xmm[6-11] should be saved and restored for Windows x64; prevents an

Update the fmt_deps function to use a new sed expression to convert the
object file name generated by the compiler into the path-transformed
name of the .o and .d files.
Prior to this patch, changing a header file would not trigger an
incremental build.

The Android NDK automatically manages the include directories. Trying
to do so manually for the Android GYP files can cause the wrong setjmp.h
to be included.

This prevents the relatively expensive token-from-coefficient lookup
function get_token(), plus a duplicate loop..

Just like for all other block modes, b_pred tokens can be read together
before starting macroblock reconstruction. This removes special cases
for b_pred in decode_macroblock() and allows to make decode_coefs_4x4()
static in detokenize.c.
While at it, remove the redundant handling and checking of plane_type
and block_index (i) in decode_coefs_4x4(). Since the function is static,
and is called only from decode_mb_tokens_4x4(), we don't need to worry
that the arguments ever go out of sync.
