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.)

Anton Khirnov 08bebeb1be Revert "all: Don't set AVClass.item_name to its default value"
Some callers assume that item_name is always set, so this may be
considered an API break.

This reverts commit 0c6203c97a.

Andreas Rheinhardt 0c6203c97a all: Don't set AVClass.item_name to its default value
Unnecessary since acf63d5350adeae551d412db699f8ca03f7e76b9;
also avoids relocations.
