Use the kernel/user shared memory to keep track of interface stats. This
eliminates the need to update the userspace stats counters with the
values from the kernel, and vice versa when updating the kernel streams.
Add a function to reverse map userspace mapped memory address to kernel
space addresses.

There isn't any immediate benefit to this, but it prepares the code for
use of shared memory for statistics.
Use the opportunity to switch accesses to these to relaxed memory order.

Switch all memory buffers used for RTP I/O from generic stack or heap
allocated memory to the bufferpool implementation. Use a per-thread
bufferpool to minimise lock contention.
This commit is just a one-for-one swap and doesn't use the bufferpool's
reference counting semantics yet.

To support asynchronous pollers which may hold references on underlying
sockets, let the poller close the socket after it has released its
references. This prevents cases of file descriptor re-use while an
underlying socket is still open.
Add reset_socket() to be used in place of close_socket() which does the
same thing except the actual closing of the socket.
Add poller_del_item_callback() for cases where more action than just
closing the file descriptor is needed.

This has been broken for a while and nobody seems to be using it since
nobody complained. Remove it.

If multiple pollers are in use, use a single poller per call instead of
assigning pollers round-robin to each socket used in the call.

The poller-per-thread feature was broken with a division by zero. Take
the opportunity to rework it and eliminate the poller_map object. Use a
simple array of pollers for media sockets, plus one global poller for
control sockets. In the regular case only one poller is created and
everything points to that poller. In the poller-per-thread case, one
poller per thread is created, plus one poller (also with its own single
thread) for control connections. All control sockets use the single
control poller, while all media sockets get assigned one poller from the
pool in a round-robin fashion.

In the file implementations follow the rules:
1. Firstly goes the correlated header file, then one empty row.
2. Secondly go system headers, so in angle-brackets, then one empty row.
3. Thirdly, go custom header files, so in double quotes,
then one empty row.
4. If there is "xt_RTPENGINE.h", it's mentioned next, but separately,
then one empty row.
5. If there are pre-processor definitions, they are added.
6. And eventually at least one empty row before the code.
In some situations it's allowed to step aside from the rules,
when inclusions are dependent on each other, so on the sequence,
and also possibly on some inline objects definitions, but if possible
to follow the rules, it's being done.

Instead of using transcoding flag `_TRANSCODING`
on the monologue level, we have to use that on the media
level in order to properly reflect the level on which
transocding is being used, and also to be able to selectively
set this for specific media sessions.

There's two flavours of this struct being in use, even though the
structs' signatures are the same. One contains socket_t objects, the
other contains stream_fd objects. Separate them out and be explicit
about which is which.

Start using the media subscriptions model
(based on newly introduced `media_subscription` objects)
in scope of `stream_packet()`.

We always need to (re)set the ssrc_map_out SSRC, even for the input
context, as this SSRC is used to look up the receiving SSRC context,
where the appropriate RX stats are stored, including the payload type in
use.
