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

Don't pass the xt_action_param into the inner functions as they don't
need it. Get the struct net pointer first and then pass that down.

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 are potentially computed from inside each subdir, and in addition
due to what appears to be a regression in GNU make 4.4, where it is
reevaluating variables that contain $(shell) functions, many times (in
the order of thousands, this was slowing down the build, were on the
Debian amd64 build daemons it went from 5m with GNU make 4.3 to 2h40m
with GNU make 4.4. Although the bulk of the slow down has been fixed
with previous commits, the remaining optimizations are only to avoid
this potentially happening again in the future, and to reduce useless
duplicate work.
Instead of trying to cache the values from within make itself, where
programming this there is extremely painful, and does not seem to be
able to greatly reduce the number of calls, because the build system
is going to be called multiple times for different targets. Simply
externalize the generation into several shell scripts, that we call
to generate a make fragment that then we include from the various
Makefiles.
For a Debian build with GNU make 4.3, this reduces the amount of total
pkg-config calls from around ~1600 to 128, for dpkg-buildflags from
~1100 down to 6, and for dpkg-parsechangelog from ~56 to 17, but the
slow down is not as significant there anyway.
For a Debian build with GNU make 4.4, this reduces the amount of total
pkg-config calls from around ~2600 to 128, for dpkg-buildflags from
~2800 down to 6, and for dpkg-parsechangelog from ~350 to 21.
For a Debian build with GNU make 4.4, this reduces the build time
on this system from 2m10s to ~ 1m30s.

Starting with GNU make 4.4, build time have massively regressed
where before they would take 5m on amd64 now can take 2h40m. While this
seems clearly broken, the release notes are filled with notices for
breaking changes, and in particular the one for passing all make
variables down to the invoked programs executed via the «shell» GNU make
function, so it is not clear what is expected breakage and what is not.
This has been reported in Debian, but not yet upstream, and while it
seems like a clear regression, it's not clear what will be the upstream
take on it. For now apply workarounds that do not change semantics, and
which do not regress with older GNU make versions.
Use the GNU make «origin» function instead of «?=» which defaults to
defining a variable as a recursive one. Coerce already defined variables
into simple ones to avoid GNU make re-evaluating these variables for
each «shell» function invocation.

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.
Closes#1860

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
