SV: [Asterisk-Dev] Change 'timelimit' on 'config' in a bridge.

[Kaloyan Kovachev]

Hi again,
 here is the patch i've made. It adds two new variables to the L() option of
the Dialapp:
   LIMIT_RECHECK_INTERVAL - if not defined L works as before - no changes in
the old dialplans are needed
   LIMIT_RECHECK_APP - if not defined simply sends a Manager Event
"RecheckTimeLimit" with info for both legs of the call
                     - if defined should start that app every
LIMIT_RECHECK_INTERVAL ms, which is not yet completed, but this patch should
be enough to
reread the new timelimit if changed via Manager.
