6024b8e46b oggdemux: Ensure that no pad values are set when setting up the mapper
Otherwise we might have arbitrary values set that are used later and can
cause undefined behaviour, as found by ossfuzz.

63e8900c47 ogg: Avoid undefined granule shift
A granule is a 64bit signed integer, shifting by 63 or more is
undefined and most likely an indication that the stream is
corrupted or invalid.

af48682d44 oggstream: Use proper type for sample calculation
If we are going to return a (potentially) 64bit integer, don't use
a 32bit one for calculation, otherwise we could end up exceeding
the maximum size of a 32bit int.

2cf5d596ee oggstream: Fix default granuleshift usage
For stream mappers that don't set a specific granuleshift, it will
have the default value of -1.

Protect the code for that and return the granule value as-is

c3006b17d1 oggstream: Add a default GstOggMap
Since the default value of a GstOggPad.map.map was 0 ... we would
end up using wrong functions from mappers() if the stream wasn't
initialized yet.

Instead of that, use a default blank/empty first entry.

8a3be7323a oggdemux: Allow start clipping for Opus
The granulepos does not have the pre-skip subtracted while timestamps do,
and the last granulepos will be shorter by the number of samples that should
be dropped because of padding in the end.

As such, extrapolating the granule of the beginning of the first frame will
lead to a negative value, which is not a problem but intentional.

packet's keyframeness.

55f98974a8 oggstream: fix a few left shifts operations on 32 bits cast to 64 bits
This should not cause any actual bug since Theora and Daala have
a maximum shift of 31, and a packet duration of 2^31 seems very
implausible. But it fixes:

657fe5efff oggdemux: don't expose Annodex CMML streams any more
This never really took off - it's hardly used anywhere
and deprecated in favour of Kate. Exposing pads just
leads to confusing 'you are missing a plug-in' messages
when people come across such streams. We could still post
the data on the bus for applications to parse.

b4d6263f38 oggdemux: fix granpos interpolation violating max keyframe distance
In case many packets fit on a page, we may not see a granpos for
a while, and granpos interpolation can wrap the 'frames since last
keyframe' part of the granpos, generating a granpos which is smaller
than what it should be.

This is fixed by detecting keyframe packets (at least for Theora),
and updating the last keyframe granpos from this.

This may still be generating potentially wrong granpos for streams
which have a Theora like granpos (keyframes, a max keyframe distance
and a count of frames since last keyframe), and which allow implicit
granules on packets. For these streams, a custom keyframe detection
routine should be plugged into their GstOggStream mapper.

bf73491077 oggstream: recognize opus headers from data, not packet count
Opus streams outside of Ogg may not have headers, and oggstream
may be used by oggmux to mux an Opus stream which does not come
from Ogg - thus without headers.
Determining headerness by packet count would strip the first two
packets from such an Opus stream, leading to a very small amount
of audio being clipped at the beginning of the stream.
