This fixes warning when compiling libvpx for PNaCl. PNaCl's version
of math.h defines M_LOG2_E.

Under a configuration change, where the bitrate suddenly decreases,
the buffer level may be larger than maximum allowed (for that first frame to be encoded after change_config).
This change keeps it clipped to its maximum level.

There were two problems with the format string in
the conditionally compiled print statement. It referred
to a variable that is no longer available and it used
incorrect format specifiers.

When a frame is dropped due to |buffer_level| < 0 for a given temporal layer,
the buffer level for the upper temporal layers was not updated (in calc_pframe_target_size()).
This change fixes that.
Also, use the layer per-frame-bandwidth for updating the buffer level
of the higher layers when a frame is dropped.

this was never fleshed out in the context of VP8, for which it was
added. for VP9 it has no meaning.

Use a separate counter for resetting the pattern upon
a change in temporal layers, and set/initialize the
layer context parameters for the new temporal layer state.
Also moved the setting of layer configuation in init_config()
to a separate function.

This is work-in-progress, it implements multiple ARF
encoding behind an experimental flag.
It adds the ability to insert multiple ARF frames into a
single ARF group. This patch implements the reordering
of the coded frames, and implements a fixed-length coding
pattern. It applies a fixed quantizer strategy based on
where the frame is in the coding sequence.
Further work to modify the rate control strategy is
ongoing and will be submitted via a set of future patches.
In this first step, each ARF group is recursively
bisected and an ARF frame added at that position in the
sequence. The recursion continues until ARF frames are
within MIN_GF_INTERVAL frames.
The code sits behind the "multiple-arf" experimental
flag ("CONFIG_MULTIPLE_ARF"). The experimental flag
"oneshotq" ("CONFIG_ONESHOTQ") also needs to be enabled
for this patch to work correctly.

When error concealment is enabled, it swaps the mi and prev_mi ptrs after
each frame is decoded. The postproc uses the mi ptr for the mode info context.
Now the postproc will use the correct mode info context.

Reduce the delta loop filter for blocks that are cyclicly refreshed.
This helps to reduce the dot artifacts that may happen
when zero_mv blocks are repeatedly loop-filtered.
This change, along with the fix in:
https://gerrit.chromium.org/gerrit/#/c/40409/
helps to reduce this artifact, but cannot remove the dot artifacts completely.

The loopfilter thread from the previous frame can be running while
starting the current frame. cpi->Source will change during this time causing
the wrong data to be copied. The refresh_x_frame flags also change, which
will cause incorrect updates of the denoised buffers.

The denoiser was writing to LAST_FRAME buffer. If LAST_FRAME isn't being
updated, the reference frame buffers were out of sync between the encoder and the
denoised raw buffers. This patch resolves the discrepancy by always writing to a work
buffer (INTRA_FRAME) and then copying from that buffer to any buffers that needs to
be updated.

1. Algorithm modification:
Instead of having same filter threshold for a whole frame, now we
allow the thresholds to be adjusted for each macroblock. In current
implementation, to avoid excessive blur on background as reported
in issue480(http://code.google.com/p/webm/issues/detail?id=480), we
reduce the thresholds for skipped macroblocks.
2. SSE2 optimization:
As started in issue479(http://code.google.com/p/webm/issues/detail?id=479),
the filter calculation was adjusted for better performance. The c
code was also modified accordingly. This made the deblock filter
2x faster, and the decoder was 1.2x faster overall.
Next, the demacroblock filter will be modified similarly.

The codec as it stood placed a keyframe one frame after a
real cut scene - and ignored datarate and other considerations.
TODO: Its possible that we should detect a keyframe and recode
the frame ( in certain circumstances) to improve quality.
