Register expression for IPv4, IPv6, and INET protocols.
Support one u32 attribute, which is the table ID.

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.

This seems to be an acceptable and reliable way to detect RTCP
multiplexed with RTP, even if `a=rtcp-mux` wasn't advertised in the SDP.
Take the opportunity to clean up __streams_set_sinks() a bit by giving
the variables better names.

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

This only exists because of RTCP indexing issues, but with the index
being in shared memory now, we no longer need this.

The requirement to continuously update stats from the kernel has been
eliminates. Remove all relevant code.

... and change to 32 bit.
Remove functions to retrieve kernel stats as they don't do anything any
more.
Add RTCP index information to /list output.

This field is duplicated with `ext_seq`, which is already kept in shared
memory and therefore preferable.
Also update all sequence number fields to 32-bit (down from 64-bit) as
there's no need for all these extra bits.
Add output seq information to /list.

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.

Require rtpe_stats to be set before allowing a target to be created.
Refactor init method into its own function.
Otherwise currently unused.

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.

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.

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.

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

DTMF requires the "end" event to be sent multiple times, requiring
sequence number adjustments after DTMF injection has finished. Add
support for this to the kernel module.

This combines the REMG_DEL_TARGET method with REMG_GET_STATS. It
retrieves the stats of an existing target, returns them to userspace,
then proceeds to delete the target.

Check all the struct sizes as part of the startup NOOP command, to try
to catch incompatible kernel module versions.
Change-Id: Ib617878e1e5a813de199c5405db3680c1e4d3351
The unified `rtpengine_message` struct has become quite large, and most
fields are not used for most of the messages sent to the kernel module.
Use command-specific structures that only contain the required
information. Adapt the I/O code and the size checks to use the correct
sizes.
Do special handling for GET_*_STATS as these commands do both input and
output at the same time. Copy in only the input portion of the struct.
(Copy-out still copies the entire struct at this point.)

This makes it possible to have different media silencing options for
different outputs. Functionally this commit alone is a no-op.

Zero SSRC are technically invalid, but the code accepts them as valid
and therefore sets up things like crypto contexts for zero SSRCs.
Consequently it's possible to have a zero SSRC first in the list of
SSRCs and other valid SSRCs later in the list, which means we can't use
the presence of a non-zero SSRC first in the list as a flag to determine
whether SSRC tracking is in use or not. Use an explicit flag instead.
