There are lots of files that don't need it: The number of object
files that actually need it went down from 2011 to 884 here.
Keep it for external users in order to not cause breakages.
Also improve the other headers a bit while just at it.

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.

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.)

It is only used by demuxers (although it is hypothetically
possible that some day e.g. a protocol might need it, but
that is unlikely given that they don't deal with AVCodecParameters).

The AAX demuxer reads a 32bit number containing the amount of entries
of an array and stores it in an uint32_t. Yet when iterating over this
array, a loop counter of type int is used. This leads to undefined
behaviour if the amount of entries is not in the range of int; to avoid
this, it is generally good to use the same type for the loop counter as
for the variable it is compared to. This is done in one of the two loops
affected by this.
In the other loop, the undefined behaviour can begin even earlier: Here
the loop counter is multiplied by an uint16_t which can overflow as soon
as the loop counter is > 2^15. Using an unsigned type would avoid the
undefined behaviour, but truncation would still be possible, so use an
uint64_t.
Also use an uint32_t for a variable containing an index in said array.
This fixes Coverity issue #1466767.
