Subject: [PATCH] CHANNEL(callid): Give dialplan access to the callid.
* Added CHANNEL(callid) to retrieve the call identifier log tag associated
with the channel. Dialplan now has access to the call log search key
associated with the channel so it can be saved in case there is a problem
with the call.
