Make the macro return the appropriate pointer type, and make sure the
free function takes an argument of the same type. This also eliminates
some boilerplate type-casting code.

Use relaxed-order atomic ops to access config variables that can be set
during run time.
Rename config_lock to keyspaces_lock as the keyspaces list remains the
only object that it protects.
All other config variables aren't settable at runtime and so don't
require locks or atomic ops.

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.

There isn't any immediate benefit to this, but it prepares the code for

In the file implementations follow the rules:
1. Firstly goes the correlated header file, then one empty row.
2. Secondly go system headers, so in angle-brackets, then one empty row.
3. Thirdly, go custom header files, so in double quotes,
then one empty row.
4. If there is "xt_RTPENGINE.h", it's mentioned next, but separately,
then one empty row.
5. If there are pre-processor definitions, they are added.
6. And eventually at least one empty row before the code.
In some situations it's allowed to step aside from the rules,
when inclusions are dependent on each other, so on the sequence,
and also possibly on some inline objects definitions, but if possible
to follow the rules, it's being done.

All timers have been moved to their dedicated timer threads, making this
mechanism obsolete.
The only victim is the timeout handling for TCP control streams. Since
other TCP streams aren't using timeout handling either, and the TCP
control socket is barely used by anyone, we can live with not having a
dedicated timeout for these streams for now.

We have to stop using objects of `struct port_pool` (media_socket.h),
becasue a newer approach introduced for ports allocations deprecates

Perform accumulation of stats only once (i.e. increasing an actual
counter) and report stats based on differences to previous values,
instead of carrying multiple stats counters for each metric and
resetting each counter to zero whenever stats are reported.
`rtpe_stats` is the global master accumulator.
`_intv` variables are intermediate and local storage for values sampled
from `rtpe_stats` at regular intervals.
`_rate` and `_diff` variables hold stats calculated from `rtpe_stats`
and the respective `_intv` variable whenever the sampling and reporting
occurs.
`stats_counters_calc_diff` is used to calculate stats as differences
between `rtpe_stats` and the last sampled `_intv`
`stats_counters_calc_rate` does the same but calculates a per-second
rate, based on a microsecond duration.
Eliminate now-useless struct global_stats_ax

When ports are closed early (while the call is still running), we must
first update a slave rtpengine with this new information (that these
ports are now closed) before actually releasing the ports ourselves. Not
doing so leads to a race condition where the master instance re-uses a
port that was just closed before the slave instance knows about the port
being closed.
We implement this using a thread-local list to keep track of ports that
were released while processing a control message, and process this list
to actually close the ports only after Redis has been updated.
Additional calls to the function to close the ports are placed in
strategic locations to make sure this is triggered in every code path.

This is useful for functions which are used both from a timer and from
other callers. These functions would reset the logging context at their
end to free the reference held by the logging context, which would
wrongly reset the logging context when the same function was called from
a different code path. Using a stack with push/pop semantics makes it
safe to use these functions from any code path.
Additionally introduce an explicit reset function that clears the entire
stack regardless of context. This reset function is called at the end of
every work iteration in every worker thread, just in case not everything
was popped from the stack.

Handling of dual stack v4/v6 was previously done by the individual
listener objects for INADDR_ANY listening addresses. If listening on
INADDR_ANY was requested, then each listener would create two instances,
one for IPv4 and one for IPv6. This works fine for INADDR_ANY but fails
for listening on host names that resolve to multiple addresses, such as
`localhost`.
Solve this by relieving the listener objects from handling this and
instead handle it in the code setting up the listeners. If a host name
resolves to multiple addresses, then set up multiple listeners (up to
two supported currently). This allows us to listen on `localhost` by
default and have both 127.0.0.1 and ::1 active. INADDR_ANY is handled
specially by also setting up :: in that case.

libcs are implementing changes to fix the year 2038 issue on 32 bit
platforms (see [1]). musl libc already went ahead and implemented it,
starting with musl-1.2.0 (see [2]).
This commit adds a new definition to lib/loglib.h:
TIME_T_INT_FMT
If __USE_TIME_BITS64 is defined (by a time64 libc, see [1]), it's set to
the proper conversions for type int64_t, PRId64. If __USE_TIME_BITS64 is
not defined, the status quo remains unchanged ("%ld" is used).
The new definition is used in the different parts of rtpengine, where
appropriate.
Note: Richard confirmed that the "%u" format in daemon/cdr.c is not
needed, so this gets swept under the rug.
These changes get rid of the new warnings that appeared with musl-1.2.0.
Below an example warning:
