This is the first step in creating this repository from the legacy openbsc.git.
Like all other Osmocom repositories, keep the autoconf and automake files in
the repository root. openbsc.git has been the sole exception, which ends now.

The abnormal case is that lchan_free ist getting called due
a RSL_MT_CHAN_REL_ACK in the RSL but the refcount of this
channel is not zero. This means that some "logical operation"
is still going on that needs to be cancelled.
Instead of always queuing up all operations in the
struct gsm_lchan use the signal framework to inform higher
layers about this abnormal case.
In gsm_04_08.c a signal handler is installed and in the
abnormal case the location updating request operation is
freed.
* introduce new notion of subsystem in addition to signal number
* no need for bitmasks of 'areas' (aka subsystems)
* pass subsystem/signal_nr/... per argument rather than by data structure
This will be used for generic registration and dispatching
of any kind of event. We will have different areas (like
with the debug interface) and each layer can define their
own struct for the event message... This is not tested yet
