PROGRESS without PROGRESS INDICATOR IE is invalid according to Q.931,
so always call pri_progress() with info flag set, even if we do not
have media yet.

"Safer" version of ftdm_clamp(), that swaps min/max parameters if
vmin happens to be larger than vmax, making sure the output will
always satisfy vmin <= x <= vmax.

Some people, it seems, were having sleepless nights from the
log messages this feature produces every 15 minutes.
Default disable the feature, because i hate repeating myself
over and over, explaining them this is a non-issue and intended
behaviour and how to disable it in the config.

FTDM_SIGEVENT_UP was falling through to FTDM_SIGEVENT_PROGRESS_MEDIA, which
does (almost) the same, so no harm, but still fix it.

Channels can be in DOWN state but reserved by an incoming call
(FTDM_CHANNEL_INUSE flag). Additionally check the flag in on_timeout_t3xx()
and skip those channels.

Do not try to send RESTART on BRI PTMP spans, libpri will just print
an error and do nothing, causing the channels to be stuck in RESTART
forever.
Add T316 (RESTART ACK timeout), which is not implemented by libpri.
The default timeout is 30 seconds (Q.931 recommends 2 minutes, but
that is a little long and libpri layer 2 is being stupid) and the
restart attempt limit to 3 (instead of 2).
Periodically send RESTART on idle b-channels in PTP NT mode.
Default interval is 15 minutes, feature can be disabled by setting
"idle_restart_interval" to 0 in the span configuration.
Allow timeout / interval values to have an additional time unit
suffix for convenience reasons, the default (no unit specified)
is milliseconds, valid units include:
w (week), d (day), h (hour), m (minute), s (second)
Only full integers are accepted, no fractional numbers, valid examples:
2w = two weeks
37m = 37 minutes
1h = 1 hour
Combinations of multiple numbers and units (e.g. "1w5d") are not supported.
New span configuration parameters:
idle_restart_interval (milliseconds / time unit suffix /
0 = disabled)
t316 / restart_timeout (milliseconds / time unit suffix)
t316_limit / restart_attempts (number of max. attempts)
