Adds a separate scale numerator for resize and superres scaling on
keyframes. They will only use this factor in their respective FIXED
modes.

RESIZE_SCALE_DENOMINATOR and SUPERRES_SCALE_DENOMINATOR were two
constants with the same value that did essentially the same thing.
This patch merges the two into SCALE_DENOMINATOR for simplicity's sake.

Unifies the command line arguments for resize and superes.
Removes resize arguments that are currently unused.

Adds "superres-mode" and "superres-numerator" arguments to configure
superres scaling.
There are only two modes right now: SUPERRES_FIXED and SUPERRES_DYNAMIC.
0 sets the fixed mode and 1 sets the dynamic mode.
For the fixed mode superres will scale to the provided numerator where
possible. The cumulative scale change over resizing and superres is
limited to 1/2, so it may have to back off.
For the dynamic mode, the provided numerator will be used as the initial
numerator. Asides from that it's just random for now.

Adds handling needed for the pre-encode downscaling for superres
encoding. Makes use of the existing resizing functionality, just
adjusting the target resolution after the resize logic and before the
resize has actually occurred.
Since the upscaling portion of superres is not yet implemented, superres
scaling is not yet allowed to trigger. The numerator is set to be equal
to the denominator and the superres_pending flag is not set.

This unit test was ported from VP9. To prevent the motion vector out of
range bug, added a motion vector unit test. In the 4k video encoding,
always forced to use extreme motion vectors and also encouraged to use
INTER modes. In the decoding, checked if the motion vector was valid,
and also checked the encoder/decoder mismatch.

Added 2 tile encoding modes:
TILE_NORMAL mode supports the large-scale tile coding up to 1024 x 1024
tiles;
TILE_VR mode supports the large-scale tile coding and also the decoding
of a single tile.
TILE_NORMAL mode allows the non-vr content to be encoded in multiple tiles
without using the coding tool that are designed for vr applications.

kMinCompressedSize was defined as a global constant, so it
was exported by default and possibly causing duplicate
symbol issues for applications. In particular, libvpx also
exports this symbol.
Instead, move the definition into the only function which
references is. As a local variable it is hidden from the
linker and not part of the global symbol table.

The "good" speed levels are universally better than the "rt" ones,
running faster to achieve the same quality.
rt mode also turned off alt refs and lag-in-frames, but these
are still accessible separately (and the low latency test case
explicitly sets them).
Some features were used by the rt scale and not the good scale.
Two additional "good" levels, 7 and 8, were added to accomidate
these features and not reduce test coverage.

This option increases runtime by 20% and is only marginally
better than good cpu-used=0:
PSNR | PSNR Cb | PSNR Cr | PSNR HVS | SSIM | MS SSIM | CIEDE 2000
-0.3382 | -0.3911 | -0.4875 | -0.2982 | -0.2992 | -0.3164 | -0.3686
It is also not well integrated with speed_features.c, which is
the main reason for the removal.

This commit implements support for twopass encoding using the xiphrc
experimental rate control system. Most of the code and logic comes
from the theora project encoder.
Currently support is limited to the bitrate targeting mode of the
rate control system and while it does visibly improve quality and does
bring rate closer to the target than the one pass mode there's still
tuning and bug fixing to be done.

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.

This commit renames deblocking_across_tiles to loopfilter_across_tiles,
to get ready for dering and clpf integration.
Change-Id: Id25b051da9b1e5cb92f35a9619662597462d9537
This commit adds a new experiment to allow disabling of loop filtering
on tile boundaries. It is implemented by adding a syntax field
"loopfilter_across_tiles_enabled" into the uncompressed frame header.
If it is set to 0, decoder and encoder will disables loop filtering for
block edges that are also tile boundaries.

Default MTU size is 0, which implies a fixed number
of tile groups. MTU matching overrides fixed tile
group. MTU matching will succeed unless a single
tile is bigger than the MTU.
--mtu-size is in bytes, and includes headers but
not transport/wrapper overheads

Also:
- For unsigned ints, don't check value >= 0 as that is always true.
- Add "-Wlogical-op" warning flag which would have warned that "logical
'or' of collectively exhaustive tests is always true" before this
patch.
