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.)

Andreas Rheinhardt 40bdd8cc05 avformat: Avoid allocation for AVStreamInternal
Do this by allocating AVStream together with the data that is
currently in AVStreamInternal; or rather: Put AVStream at the
beginning of a new structure called FFStream (which encompasses
more than just the internal fields and is a proper context in its own
right, hence the name) and remove AVStreamInternal altogether.

James Almer b9c5fdf602 avformat: move AVStream.{parser,need_parsing} to AVStreamInternal
Those are private fields, no reason to have them exposed in a public
header.

bnnm ebb83e2dc0 avformat/msf: fix codec 4 (joint stereo ATRAC3) and align
Codec 4 (frame size 98) uses joint stereo per spec and examples.
Also removed an incorrect "align" var which wasn't used anyway (it was overwrittern).

Probably all/only .AT3 of frame size 98 are JS, too.
