Allocate per-payload-type stats buffers in shared bufferpool. Push these
to the kernel module for direct tracking of bytes/packets stats. This
eliminates the need to return these values in the /blist data and
continuously update the userspace stats.
The accomodate updating the payload-type tracker, we use the "last
received" timestamp from the kernel module together with the "last seen
payload type" to give similar results as before.

This obsoletes the need to retain the last seen kernel stats and track
updates to the counters in order to set call states.

Require rtpe_stats to be set before allowing a target to be created.
Refactor init method into its own function.
Otherwise currently unused.
Change-Id: Ic66e7f92f875ede1a3a2d55fee4ed53c39ff93be
Rename the "noop" method to "init" and split up the function to open the
table into two parts. Open the control file first, then do the mmap(),
then init other things, then finally call the init method.

... and move to kernel module.
Keep the common fields at the beginning of the header in place for both
user space and kernel space, and move the remaining (user only) fields
into a separate header. The kernel module doesn't need to know about
these extra fields.

Keep two separate timestamps, one updated by userspace code only and the
other updated by kernel only. This way we can tell where the packet
processing happens. For code that wants to report only the last
timestamp regardless of which one of the two it is, we add a convenience
function that just returns the newer one.

This leaves the TOS value as the only leftover to be not in shm.
The kernel_stats structures remain for the time being as they're needed
to determine whether kernel forwarding is done or not, as well as for
global stats.

Allocate memory from bufferpool for per-stream stats. No functional
change, but it allows sharing these between kernel and user space.
Change-Id: I370a49e1d94bb91c7fd0a2bc7d00ba65f99c4f6a
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.
Change-Id: Iaa5f9488061a12103e57faf27b3979521778cea8
These will be shared between userspace and kernel space and so the
definitions must be part of the kernel includes.

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.

using str_init_dup_str doesn't leave enough room for appending encryption
related pieces to the end of the packet when used for, eg, dtmf
injection

Only increase the SRTCP index when encrypted SRTCP is actually in use.
This would be apparent when a stream is switched from RTCP to SRTCP.
