083cbc930d snappy: Refactor so ff_snappy_uncompress() uses an existing buffer
Some uses of Snappy require uncompressing to positions within
an existing buffer. Also adds a function to get the uncompressed
length of Snappy data.

ae5a8dca67 hap: Fix slice size computation
A bug was introduced in 977105407c whereby when
frame height wasn't divisible by the number of threads, pixels would be omitted
from the bottom rows during decode.

977105407c hap: Decode using optimal slices sizes
Enjoy some cache locality and use less threads.
About 5x speedup (from 60ms to 12ms to decode a 4k frame).
