ftmod_libpri: Bail out with an error message if libpri is too old and selected trunk type is BRI or BRI_PTMP

Requires libpri-1.4.12_beta1 or newer!
Completely untested, AOC-S/D/E ChargingRequest operations are sent to NT (DTAG BRI PTMP),
but rejected with "Unrecognized Operation".

NOTE: FreeTDM core needs support for this to be useful!
      Only AOC-E events are decoded and sent to the log.

To enable:
    Set (or add) <param name="opts" value="aoc"> in your
    libpri_spans span config.

ftmod_libpri: Write fatal error message during span configuration to console (and to span error log).
Signed-off-by: Stefan Knoblich <s.knoblich@axsentis.de>

"all" and "none" can only be used alone,
other flags are additive.

freetdm: convert ftmod_libpri (+ libpri_spans) to use new ftdm_configure_span_signaling() interface.

This fixes several issues with parameter handling (e.g. default alaw/ulaw selection being totally useless).
