ivfdec: webm reader support

This patch enables ivfdec to decode WebM files. WebM demuxing is
provided by the Matthew Gregan's Nestegg library.

This patch also makes minor changes to the timebase->framerate
handling when doing Y4M output. For WebM files, the framerate is
guessed by looking at the first second of video. For IVF files,
the timebase=1/(2*fps) hack is still in place, but is only used
if the timebase denominator is less than 1000. This is in anticipation
of change I8d25b5b, which introduces the distinction between
framerate and timebase to ivfenc. In the case of high resolution
timebases, like 100ns, we would have to guess the framerate
like we do for WebM, but since WebM support in ivfenc will
deprecate IVF output, we just assume 30fps rather than writing the
lookahead code.

Centralize mb skip state calculation

This patch moves the scattered updates to the mb skip state
(mode_info_context->mbmi.mb_skip_coeff) to vp8_tokenize_mb. Recent
changes to the quantizer exposed a bug where if a macroblock
could be coded as a skip but isn't, the encoder would run the
loopfilter but the decoder wouldn't, causing a reference buffer
mismatch.

The loopfilter is controlled by a flag called dc_diff. The decoder
looks at the number of decoded coefficients when setting this flag.
The encoder sets this flag based on the skip state, since any
skippable macroblock should be transmitted as a skip. The coefficient
optimization pass (vp8_optimize_b()) could change the coefficients
such that a block that was not a skip becomes one. The encoder was
not updating the skip state in this situation for intra coded blocks.

The underlying issue predates it, but this bug was recently triggered
by enabling trellis quantization on the Y2 block in commit dcd29e3,
and by changing the quantizer range control in commit 305be4e.

Fix loopfilter delta zero transitions

Loopfilter deltas are initialized to zero on keyframes in the decoder.
The values then persist from the previous frame unless an update bit
is set in the bitstream. This data is not included in the entropy
data saved by the 'refresh entropy' bit in the bitstream, so it is
effectively an additional contextual element beyond the 3 ref-frames
and the entropy data.

The encoder was treating this delta update bit as update-if-nonzero,
meaning that the value would be refreshed even if it hadn't changed,
and more significantly, if the correct value for the delta changed
to zero, the update wouldn't be sent, and the decoder would preserve
the last (presumably non-zero) value.

This patch updates the encoder to send an update only if the value
has changed from the previously transmitted value. It also forces the
value to be transmitted in error resilient mode, to account for lost
context in the event of lost frames.

Use movq instead of movdqu.

Movdqu is more expensive (throughput, uops) than movq.  Minimal
impact for newer big cores, but ~2.25% gain on Atom.
