Andreas Rheinhardt	4f58372c10	avcodec/hap: Avoid unnecessary opt.h inclusion It presumably exists because HapContext contains an AVClass. Yet AVClass is actually defined in log.h and even this inclusion can be avoided by struct AVClass. This avoids opt.h inclusions in hap.c and hapdec.c.

Tom Butterworth	bd6fa80d56	avcodec/hap: add "compressor" option to Hap encoder to disable secondary compression The secondary compression in Hap is optional, this change exposes that option to the user as some use-cases favour higher bitrate files to reduce workload decoding. Adds "none" or "snappy" as options for "compressor". Selecting "none" disregards "chunks" option: chunking is only of benefit decompressing Snappy.
