Said function has been added in libpri-1.4.11 and breaks
building with older libpri versions (i.e. the passive one for ftmod_pritap).

Check for pri_maintenance_service() in configure and disable
the "maintenance" subcommand if it is not available.

FS-4978 --resolve this is fine besides one minor change to only consider this path when we are doing passthru

Yeah, right, discard the incoming audio data when the b-channel is active...

Reverse the check, so ftdm_read() on an active mISDN b-channel will
be able to read audio data from the RX socketpair and not kill
the call from repeatedly timing out in poll().

Fixes:
    [WARNING] mod_freetdm.c:775 Too many timeouts while waiting I/O in channel FreeTDM/1:1/XX device 1:1!
    [ERR] mod_freetdm.c:820 clearing IO in channel FreeTDM/1:1/XX device 1:1!

epoll_wait() on the B-channel socket may indicate pending messages, but
recvfrom() returns EAGAIN. Retry a few more times (up to 5 retries)
to get the pending message.

Fix segfault on shut down of SQL queue manager in rare case where registration cleanup is firing at the same time the queue manager is shutting down.

os.environ['CFLAGS'] raises a KeyError if no CFLAGS variable is set in
the environment.  So instead we use os.environ.get('CFLAGS','') which
will return the empty string in the event no CFLAGS variable is set.

The previous problematic pattern originated from the suggested code
here for importing the build environment in SCons:

state, rather than directly probing inside the T.31 structures.

Various modules which lacked routines to get at the sub-structures now
have them.
The tests have been tweaked so they only access internals where essential.

FS-4958 --resolve thanks but again you could have submitted a patch so I did not have to hunt the 3 million lines of code for the line in question
