Summary:                    Aborted inbound trunk call to FXO analog port causes
internal extensions (SIP or DAHDI) to ring forever.
Description: 
Confirmed with a TDM800P with 1x 1port FX0 module and 1x 4port FXS module.

The only way to stop the ringing extension, was to pick it up.

The senario was:
  FX0 connected to outside line.
  FXS connected to analog phone.
  ring home line (from cellphone).
  wait for internal FXS connected phone to ring 1 or 2 rings. Hangup call
from mobile. 
  FXS connected phone keeps ringing forever.
  To stop the ringing, pickup ringing handset.

Deployed 1.6.1.0 branch, with same configs, no problems now.

---------------------------------------------------------------------- 
I've implemented a callback in to chan_dahdi called set_ringtimeout which
sets dahdi_pvt->ringt, the few places in sig_analog that set p->ringt now
call set_ringtimeout.

Although working (correctly stops ringing extensions after call is
aborted), it feels like the 'ringt' timer is at the wrong level, it should
be in the sig_analog module.

The distinctive ring detection in sig_analog relies on the local copy of
ringt, not the dahdi copy, I'm not sure if it's working.
