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.
