Andreas Rheinhardt 4a4dcde339 avformat/internal: Move FF_FMT_INIT_CLEANUP to demux.h 
and rename it to FF_INFMT_INIT_CLEANUP. This flag is demuxer-only,
so this is the more appropriate place for it.
This does not preclude adding internal flags common to both
demuxer and muxer in the future.

Andreas Rheinhardt b800327f4c avformat/avformat: Add FFInputFormat, hide internals of AVInputFormat 
This commit does for AVInputFormat what commit
59c9dc82f4 did for AVOutputFormat:
It adds a new type FFInputFormat, moves all the internals
of AVInputFormat to it and adds a now reduced AVInputFormat
as first member.

This does not affect/improve extensibility of both public
or private fields for demuxers (it is still a mess due to lavd).

This is possible since 50f34172e0
(which removed the last usage of an internal field of AVInputFormat
in fftools).

(Hint: tools/probetest.c accesses the internals of FFInputFormat
as well, but given that it is a testing tool this is not considered
a problem.)

Florian Nouwt f067fcb9df mobiclip: fix copyright headers 
The Mobiclip related code was based on Mobius (https://github.com/adibsurani/Mobius),
which was based on my original reverse engineering efforts (https://github.com/Gericom/MobiclipDecoder).
This commit adds the appropriate copyright headers on the related files.
