hap: Fix slice size computation
...
A bug was introduced in 977105407cae55876041dddbf4ce0934cdd4cd6c whereby when
frame height wasn't divisible by the number of threads, pixels would be omitted
from the bottom rows during decode.

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).

avcodec/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.
