We don't track individual uses of the shared memory, so we can't safely
free it when the mapping is closed, as the internal forwarding targets
may still point into it. Delay freeing until the table itself is freed.
Each mmap then counts as another reference on the table. Unmap then
simply decreases the reference count but never actually frees the pages.

Maybe this is correct now?

We don't need contiguous physical pages, we only need contiguous virtual
memory. This allows for larger allocation sizes.

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.

These macros were used for development only and are not needed any more.
Their names collide with an upstream patch, making compilation fail on
kernels >= 6.12. Just remove these wrapper macros altogether.

This patch forces rtpengine to use the IPv4 TTL and IPv6 hop limits set
on the host for proxied packets in kernel mode.
Beforehand, the TTL was always set to a hardcoded value of 64. While
this is the default almost everywhere, it may be desirable to be able to
set a higher value. Especially when interfacing with complex carrier
backbone networks.

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 array is only conditionally partially filled, but then
unconditionally copied, so we need to zero it out.

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.

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.

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.
Change-Id: I158f18098e018d2870b797f1a196baa03a0e0fb7
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.

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.

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