This commit does for AVInputFormat what commit
59c9dc82f450638a3068deeb1db5c56f6d155752 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 50f34172e0cca2cabc5836308ec66dbf93f5f2a3
(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.)

The discrepancy between the definition and the declaration
in allformats.c is actually UB.
