Remove the actual hash and just keep a linked list. Always move most
recently used entries to the front of the list, which also obsoletes
tracking the last used time stamp.

Keep outgoing RTP timestamps consistent between different instances of
the DTX buffer. Update affected tests.

If the last used PT was a different one, check if it was an unknown PT.
If it was, then DTX can remain active, as the packet would have been
blocked.

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.

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.

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.

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.

Use allocators that return memory blocks aligned to the requested size,
instead of generic malloc. This makes it easier to play tricks with the
memory blocks.

Adds a new config section that allows adjusting behaviour for certain

Special codec handler to support not forwarding (nor any processing
whatsoever) of particular payload types at all. Support this in the
kernel module as well.
Change-Id: If10227affa54307e1e9b448eadd0bf2bfc5774ba
Only use the codec handler's "kernelize" flag to determine whether a
particular payload type can be handled by the kernel or not. It's
supposed to be a reliable indicator, making checking the other flags
unnecessary.
