This patch adds a buffer-based rate control for temporal layers,
under CBR mode.

Added vpx_temporal_scalable_patters.c encoder for testing temporal
layers, for both vp9 and vp8 (replaces the old vp8_scalable_patterns).

Updated datarate unittest with tests for temporal layer rate-targeting.

Update the local makefile to build all the files and the test
application by default to simplify build verification.

50fa5859 Removing examples code generation and making them static.

the examples have been c files, not generated from text. this removes
GEN_EXAMPLES and replaces it with EXAMPLES, building the source directly
rather than copying it to the build folder

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.
