Add support for "q921_all"/"q931_all" to parse_debug() ("debug" span parameter), taken from
ftmod_libpri.

Passive libpri's raw dump feature is broken (e.g. I-frames missing), so
add "q921_raw" hexdump support to the pritap I/O read/write function.

AM_CONFIG_HEADER is deprecated in automake 1.13.1 (and temporarily not available in 1.13),
the replacement is available in autoconf-2.59 (and maybe before).

NOTE: Remove sed hackery when upstream has released a fixed version

Same as pri_maintenance_service(), use HAVE_LIBPRI_MAINT_SERVICE.

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.
