The stub is used for unknown payload types. Specialise the handler
function for it with an extra check for DTX usage. This effectively
blocks RTP packets with unknown payload types if DTX has been
configured. Forwarding RTP packets with unknown payload types can
interfere with a clean output stream generated by the DTX buffer.

Shutting down a DTX buffer means that it may restart at an unknown later
time. Reset TS tracking when shutting it down so that if it does
restart, it receives a fresh TS state, instead of continuing on the
previous timestamps, which may then be wrong.

Extend PT tracker to not just track the most used PT, but also which PT
has been used last. Use a simple circular array.
Use this new tracking to determine whether a DTX buffer should remain
active. The "most used PT" approach isn't reliable for this, as it leads
to a DTX buffer restarting only after the PT has become the "most used,"
so only after about 10 packets. Meanwhile a newly appearing SSRC would
have a new DTX buffer active immediately. Being strict about which PT
was used last resolves this inconsistency.

If a packet is received for a codec that should have an active DTX but
doesn't, drop the packet instead of forwarding it without being
processed. In this case we expect that some other codec has an active
DTX buffer, and forwarding the packet would interfere with a clean
output stream.

The GLib slice allocator has been obsoleted. Having a mixture of two
allocators can lead to hidden issues on systems that use different
implementations. Take the leap and replace everything with g_new/g_free.

Media IDs are supposed to be unique. Non-RFC OSRTP may however lead to
duplicated media sections with the same media ID. Use a hash table to
track which media IDs have already been seen, and ignore any duplicates.

Make sure that in tests with MoH there are no RTP packets
coming after the call is done.
Expected is that all packets have been received
during the signaling exchange.

A dummy function to ignore the fact
whether RTP packet(s) received or not.
Useful in a combination with rcv_no().

This mode is only supposed to be used by cases when:
- in-dialog offerer doesn't have own MoH capabilities; and
- still want the recipient to hear the MoH music; hence
- an offerer checks whether a recipient is capable of MoH,
and launches a player based on given capabilities;
- the rest functions the same as with usual MoH hold;
Other information:
- `mode=reflect` is only to be used within dialog,
so, it's not meant for a session origination,
and hence stands alone from other MoH option flags
that actually give a metadata (e.g. blob data)
- `mode=reflect` hence contradicts with `mode=sendrecv`
which in its turn serves another purpose
Usage:
- `moh => { mode => 'reflect' }`

Decoding and encoding may have taken some time. Grab an updated "now"

With reuse-codecs, we still need to place the codec from the SDP into
our prefs list, even if it's already present, as the format options may
have changed. Update one affected test case.

Instead of start-up options just use the text
file for configuring things, easier and simpler to keep.
Additionally: introduced config options:
- `moh-attr-name = rtpengine-hold`
- `moh-prevent-double-hold = false`
Fix tests accordingly.

Protects against double MoH played,
e.g. when inadvertently two rtpengine instances try to trigger MoH.
This gives a clue to the current rtpengine instance,
that another one already started MoH for this call.
By default is set to false.

Remove the sorted pointer array and the associated lock. We can now
directly look up the shard associated with a particular memory block and
so this isn't needed any more.

Allocate all bufferpool shards of the same size, regardless of
underlying allocator. This way increase memory usage a bit, but we're
already quite heavy on that, so no big deal.
