This CL changes libvpx to call a function when a frame buffer
is needed for decode. Libvpx will call a release callback when
no other frames reference the frame buffer. This CL adds a
default implementation of the frame buffer callbacks. Currently
only VP9 is supported. A future CL will add support for
applications to supply their own frame buffer callbacks.

Inlcudes a number cleanups:
1. Moves the one-pass pre-encode parameter setting functions
to vp9_ratectrl.c
2. Deprecates per_frame_bandwidth in RATE_CONTROL structure
3. Removes target_bandwidth in cpi structure since it is not used.
4. Various renaming of functions

There is no bit-stream change in 2-pass, one-pass cbr and one-pass
vbr modes.

This isn't strictly necessary, but makes the file more consistent
with the other arm assembly source files.

Avoid substitution of substrings by using \b to make sure the
substituted strings are at word boundaries.

This is an adaption of the corresponding changes to ads2gas.pl
from 7ebcaeb0.

older versions of visual studio did not include the trailing \. this
moves the objects to their intended location: the project subdirectory

int -> size_t for threshold values. this silences a few signed/unsigned
comparison warnings

avoid wrapping msvc includes with extern "C"; this breaks some visual
studio builds of the (c++) tests.

The rest of the code uses stdint types and this makes porting
easier.

This lets the caller pass a string literal for the codec id.
