The ATTRIBUTE_PACKED caused something to break in MB_MODE_INFO.
boundary_info got corrupted and moving InterpFilter around in
MB_MODE_INFO could cause a segfault or the problems to go away (for
instance by moving InterpFilter to the end of the struct).  Perhaps
something in MB_MODE_INFO is sensitive to alignment.  This should be
investigated further and get fixed or documented, but for now remove
the attribute.

- Enum values are generated implicitly, and hard-coded #defines are not
required.
- We use ATTRIBUTE_PACKED to indicate that the enum should still use the

Replaces division with multiplication in self-guided
filter.

The guided filter requires computation of:
n^2.s^2/(n^2.s^2 + n^2.e).
This is now implemented by computation of n^2.s^2/n^2.e followed
by using a lookup table for the function f(x) = x/(x+1).
To compute n^2.s^2/n^2.e, we use an integer multiplication based
implementation which becomes feasible since n^2.e can only
take a few values and their corresponding multipliers can be
pre-computed.
There is also another divison by n, that is also integerized.

This commit produces a bit-exact bitstream because prior calls to code
 the tx_size using aom_write_tree() would automatically convert the
 aom_tree_index on the fly to a CDF.
The tx_size_cdf[]'s are now computed once per frame.
Based on recent tests, this patch reduces decode time by 4%.

Which was a workaround to balance the quality between
luma and chroma when PVQ is enabled, by
1) skipping PVQ DC RDO for chroma and
2) using smaller lambda value (x0.5) for intra prediction of chroma,
intended to spend more bits and thus improve quality for chroma.

This commit implements a new rate control system which was ported from
Daala's rate control system (which was based off of Theora's rate
control system) to the encoder. Its aim is to address the weaknesses of
the current rate control system and eventually serve as its replacement.

This is still work in progress. So far this commit only implements
support for single pass encoding for constant quality and bitrate
targeting.
Additional commits which implement two-pass support and the rest to
match the feature set of the current rate control system are coming
soon.

The rate control system hasn't been fully tuned (and will likely need
additional tuning as the encoder's development progresses) and does
contain some "hacks", to convert the quality to a quantizer value
(empirical) and to tweak the quantizer in between golden frames (which
uses some code from the current rate control system as well as code
which attempts to model what that code does), the latter of which is
only in the constant quality codepath.

Bitrate targeting works much better than the current rate control
system's targeting and will actually closely match the rate specified by
the user without the current rate control system's bursty behaviour.

Change-Id: I1882e48bfb1404ea7b83ef410298484939601796

When DAALA_EC is enabled, calls to aom_read_tree() and aom_write_tree()
 would automatically convert the aom_tree_index and aom_prob into a CDF
 and call the aom_read_cdf() or aom_write_cdf(), which causes an
 error if DAALA_EC is enabled without EC_MULTISYMBOL.
This patch moves the conversion functions from daalaboolreader.h and
 daalaboolwriter.h into bitreader.h and bitwriter.h respectively, and
 only calls the conversion functions if EC_MULTISYMBOL is enabled.
This allows DAALA_EC to be enabled without EC_MULTISYMBOL and is a
 bitstream change when both ANS and EC_MULTISYMBOL are enabled as calls
 to read and write trees will automatically be converted into calls that
 read and write cdfs.
