Only the first element of the array is used currently, the other
elements are in preparation for a new muxer calculating multiple
hashes.
Also move alloc/init code from the write_header() functions to
dedicated init() functions, and the cleanup code from the
write_trailer() functions to dedicated deinit() functions.
hash_free() and framehash_free() turn out to be identical here,
but will differ in the subsequent commit, so they are not consolidated.

Only the frame* muxers support the format_version option.
Use macros to ease the proliferation of identical options to
coming muxers as well.

Also, make every addition except for sidedata part of version 1 instead of the
