Checking the stderr makes a little sense, since it's an integer
value (usually equal to 2). The actual intention, most likely,
was to check 'stderr_target' against NULL.

Before this patch, the RTS:ind was crafted up in the stack when
receiving the DL_BLOCK.ind. This created some problems since the
internal low level state has to be updated in between signalling
DL_BLOCK.ind and RTS.ind, as there's a fn-advnace of one block between
those 2 signals (hence the timeslot allocation has to be applied at the
time when the fn-advance is applied).
This is actually not fixing the whole issue, since there's several
timeslots and hence the following events will have the internal timeslot updated
during the event in the middle, hence potentially causing problems in the
remaining TS:
DL_BLOCK.ind(FN=N, TS=1), RTS.ind(FN=N+4, TS=1), DL_BLOCK.ind(FN=N, TS=2)
In any case, this decoupling already improves the situation and is step
needed anyway towards fully fixing the problem (by, for instance,
maintaining a timeslot state duplicated both for DL and Ul directions,
since they drive based on differnet FN time (1 PDCH block).

sched_fn_ul() does not support RSL_CHAN_OSMO_PDCH, so it would always
return the current time, which in most cases is not the correct time
for scheduling a block. Actually, we don't really need this function
because the Tx Fn is provided to us by the upper layers - just use it.

Accessing a header file from outside of the sub-project requires
using the relative path ("-I$(top_srcdir)/../layer23/include"),
which does not resolve properly during make distcheck.
The '../layer23/include/l1ctl_proto.h' is actually a symlink too.

Remove the paragraph about writing to the Free Software Foundation's
mailing address. The FSF has changed addresses in the past, and may do
so again. In 2021 this is not useful, let's rather have a bit less
boilerplate at the start of source files.

Some logging categories use LOGL_INFO or even LOGL_DEBUG. Lets set those

This allows us to bind the multicast sockets to a given network device
and/or to set the TTL of the multicast frames and hence control their
reach in terms of number of network hops.

Unlike the DATA messages, traffic frames may have different length.
Instead of having fixed payload (i.e. TCH frame) length, let's
introduce a flexible array member. This would allow one to
calculate the frame length using the MSGB API.

virtphy uses UDP multicast to communicate with its osmo-bts-virtual
counterpart. At the momemnt SO_REUSEADDR is not applied for those
multicast connections because OSMO_SOCK_F_UDP_REUSEADDR is not set. This
makes prevents the proper function of UDP multicast.
- Make sure OSMO_SOCK_F_UDP_REUSEADDR is set

We make sure that all allocations are tracked back to one talloc root
context, and install the usual SIGUSR1 handler to dump the talloc
