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.)

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.

This is possible now that the next-API is gone.

Up until now, the TiVo demuxer parse an array of SEQ entries, yet it has
never ever made any use of them. In fact, parse_master, the function
parsing said table, only influenced the outside world in three ways: Via
an excessive amount of error message in case a certain parameter is not
what it expected; via an allocation (the aforementioned write-only
array); and by setting a certain parameter (ty->cur_chunk_pos), but that
parameter is always overwritten before it is used (it is overwritten
in get_chunk() on success and if get_chunk() fails, the error is
returned to the caller anyway). So remove the array and the function
used to parse it.

It is not uncommon to find code where the caller thinks to know better
what the return value should be than the callee. E.g. something like
"if (av_new_packet(pkt, size) < 0) return AVERROR(ENOMEM);". This commit
changes several instances of this to instead forward the actual error.

This was the only case in the source that uses a hexadecimal shift value.
The change removed a special case in respect to greping
