... so that the desired wav channel can be controlled when producing a
mixed audio file
When a mixed wav file is created, the channels in the wav container are
currently allocated in the same order as each SSRC is received, meaning
it is impossible to know which channels have been allocated to the offer
or answer side of the call. Furthermore if there is a reinvite or media
file played, these are also allocated in the order that SSRC is received
- so an "answer" could end up sharing a channel with an "offer" with no
way of knowing this.
This patch allows you to specify how many channel slots should be
allocated within the mixer, and allows you to then specify which slot is
assigned to each media in the call (this will usually be 2 slots in
total, slot 1 for answer, slot 2 for offer or vice versa).

If a stream has been pushed to the kernel from anything other than RTP,
even though RTP is expected, we get a forwarding entries without any
SSRCs. This is valid, but once actual RTP is received, it needs to be
passed on to user space, so that SSRC contexts can be set up.
Possible fix for #1855

Move printing of attributes to a separate func,
in order to be able to re-use this print during
the same media section iteration (e.g. with OSRTP).
Later on this func is to be merged with the
`print_sdp_media_section()` function, after
the sdp_replace is fully deprecated.

If there are no more tokens, instead of returning a null string as
remainder, set the remainder to the end of the original string with a
zero length.
Update two places in the code where this makes a difference.

The subscriptions must be removed first and the update function must be
called second. Otherwise unsubscribe doesn't have any immediate effect.

Added support of the AS bandwidth attribute for the
SDP session level. Will be required later for the SDP
formatting in `sdp_create()`.

Independently from the fact if a monologue already
has the `->session_sdp_orig` object set, update it
accordingly to the latest origin taken from
the currently processed SDP.
In this case such option flags as `replace_origin`,
`replace_origin_full` or `force_inc_sdp_ver` are
ignored, because their handling is covered using
the `->session_last_sdp_orig` object.

Same as ptime but for the maxptime.
Also add replication of it.
This is required later to be used for the sdp_create() handling.
Additionally: fix tests, because maxptime now takes another
place within the media session, which doesn't affect functionality.
