Implemented as a variant of the hash muxer, reusing most functions,
and making use of the previously introduced array of hashes.

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.

The pointer arguments to memcpy (and several other functions of the
C standard library) are not allowed to be NULL, not even when the number
of bytes to copy is zero. An AVEncryptionInitInfo's data pointer is
explicitly allowed to be NULL and yet av_encryption_init_info_add_side_data
unconditionally used it as a source pointer to copy from. This commit changes
this so that copying is only done if the number of bytes to copy is > 0.
Fixes ticket #8141 as well as a part of ticket #8150.

It's often not obvious how option constants relate to numerical values.
Defaults are sometimes printed as numbers and from/to are always printed as numbers.
Printing the numeric values of options constants avoids this confusion.
It also allows to see which constants are equivalent.

-segment_list_type <int> E........ set the segment list type (from -1 to 4) (default -1)

Integer values should not be printed using format specifier '%g' which leads to inexact display in case of higher values.

The reason to add this layer is that it is used by srcnn in vf_sr.
This layer is currently ignored in native mode. After this patch,
we can add multiple outputs support for native mode.
