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.

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.
