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.

The superframe index is also mandatory with daala_ec for the same
reason it is mandatory with ans, e.g., with both entropy coder
backends the buffer length is not known when calling aom_reader_init(),
see commit 15c1aa60f3.
This patch disables the same tests for CONFIG_DAALA_EC that are disabled
when CONFIG_ANS is enabled with CONFIG_EXT_TILE.

Due to the way the daala entropy coder handles raw bits, the current
test is broken because the buffer length is not known when calling
aom_reader_init() is called.

Decoding superframes correctly requires computing the end of the
frame contents in the bitstream precisely. This patch enables
ext-tile to do so.
Also extended superframe_test to test with multiple tiles if using
ext-tile.

No need to do avoid shortcuts when all we are testing is the superframe
syntax. Decreases the run time up the VP10 version of the test from 22
seconds to 3 seconds on my machine.

The superframe index marker byte carries data in the lower 5 bits. Only the
upper 3 should be used as part of the mask to detect it. By masking with
0xf0, the previous code was incorrect for frames over 65k bytes.

A 'superframe' is a group of frames that share the same PTS, but have a
defined decoding order. This commit adds the ability to append an index
to such a group of frames, allowing for random access to the constituent
frames. This could be useful for frame-level parallelism or partial
decoding in a multilayer scenario.
Decoding the stream serially without such an index should work as a
fallback, and VP9/TestSuperframeIndexIsOptional verifies that.
