Removes certain cases of feedback of active_worst_quality,
and removes it from the RATE_CONTROL structure. Now active
worst quality is expected to be computed locally in the
q picking function during the encode.
Making temporal filter strength depend on avg_frame_qindex
rather than on active_worst_quality actually improves
performance esp. for yt.

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.

Some cleanups on frames_to_key, frames_since_key.
Also removes the unused fixed_q parameters in vp9.

Various cleanups and refactoring.
Removes feedback of active worst qaulity and uses last_q
instead to make the interface cleaner. Active worst quality
is now decided only once for a frame being coded in the
beginning based on last_q and other stats. Also, adds other
cleaups on last_q to store also the last_q for altref frames,
and reduces the altref interval a little.
The output does change a little.

Includes various cleanups.
Streamlines the interfaces so that all rate control state
updates happen in the vp9_rc_postencode_update() function.
This will hopefully make it easier to support multiple
rate control schemes.
Removes some unnecessary code, which in rare cases can casue
a difference in the constrained quality mode output, but
other than that there is no bitstream change yet.

Moves all post encode rate control updates to a separate function
plus other cleanups.

Removes the active_worst_qchanged variable since it is never
set to 1.

Moves all rate control variables to a separate structure,
removes some currently unused variables,
moves some rate control functions to vp9_ratectrl.c,
and splits the encode_frame_to_data_rate function.

Some minor refactoring code relating to estimates of
bits per MB at a given Q and estimating the allowed Q range.
Most of the changes here were included in a previous commit.
This commit seeks to separate out the refactoring from more
the material changes.
Two #define control flags have been added for experimentation.
ONE_SHOT_Q_ESTIMATE force the two pass encoder to
use its initial Q range estimate for the whole clip even if this results
in a miss on the target data rate. In effect this tightens the Q range
seen at the expense of rate control accuracy.
DISABLE_RC_LONG_TERM_MEM is a related flag that disables the
long term memory in the rate control. Local adjustments are still
made to try and better hit the rate target on a per frame basis but
the impact of rate control misses is not propagated to the remainder
of the clip. This means that for example an overshoot early on will not
cause frames later in the clip to be starved of bits. Again the result
of this relaxation amy be less rate control accuracy especially on short
clips.
The flags are disabled by default for now.

Removing redundant 'extern' keywords and parentheses, fixing indentation,
making variable names lower case, using short expressions x *= c
instead of x = x * c, minor code simplifications.

For coefficients, use int16_t (instead of short); for pixel values in
16-bit intermediates, use uint16_t (instead of unsigned short); for all
others, use uint8_t (instead of unsigned char).
