Merge the new Channel Event Logging (CEL) subsystem.

CEL is the new system for logging channel events.  This was inspired after
facing many problems trying to represent what is possible to happen to a call
in Asterisk using CDR records.  For more information on CEL, see the built in
HTML or PDF documentation generated from the files in doc/tex/.

Many thanks to Steve Murphy (murf) and Brian Degenhardt (bmd) for their hard
work developing this code.  Also, thanks to Matt Nicholson (mnicholson) and
Sean Bright (seanbright) for their assistance in the final push to get this
code ready for Asterisk trunk.

+; Asterisk Channel Event Logging
+;
+; Channel Event Logging is a mechanism to provide fine-grained event information
+; that can be used to generate billing information. Such event information can
+; be recorded to databases and files via pluggable backend modules.
+;
+
+[general]
+
+; CEL Activation
+;
+; Use the 'enable' keyword to turn CEL on or off.
+;
+; Accepted values: yes and no
+; Default value:   no
+
+;enable=yes
+
+; Application Tracking
+;
+; Use the 'apps' keyword to specify the list of applications for which you want
+; to receive CEL events.  This is a comma separated list of Asterisk dialplan
+; applications, such as Dial, Queue, and Park.
+;
+; Accepted values: A comma separated list of Asterisk dialplan applications
+; Default value:   none
+;
+; Note: You may also use 'all' which will result in CEL events being reported
+;       for all Asterisk applications.  This may affect Asterisk's performance
+;       significantly.
+
+apps=dial,park
+
+; Event Tracking
+;
+; Use the 'events' keyword to specify the list of events which you want to be
+; raised when they occur.  This is a comma separated list of the values in the
+; table below.
+;
+; Accepted values: A comma separated list of one or more of the following:
+;  ALL              -- Generate entries on all events
+;  CHAN_START       -- The time a channel was created
+;  CHAN_END         -- The time a channel was terminated
+;  ANSWER           -- The time a channel was answered (ie, phone taken off-hook)
+;  HANGUP           -- The time at which a hangup occurred
+;  CONF_ENTER       -- The time a channel was connected into a conference room
+;  CONF_EXIT        -- The time a channel was removed from a conference room
+;  CONF_START       -- The time the first person enters a conference room
+;  CONF_END         -- The time the last person left a conference room (and
+;                      turned out the lights?)
+;  APP_START        -- The time a tracked application was started
+;  APP_END          -- the time a tracked application ended
+;  PARK_START       -- The time a call was parked
+;  PARK_END         -- Unpark event
+;  BRIDGE_START     -- The time a bridge is started
+;  BRIDGE_END       -- The time a bridge is ended
+;  3WAY_START       -- When a 3-way conference starts (usually via attended xfer)
+;  3WAY_END         -- When one or all exit a 3-way conference
+;  BLINDTRANSFER    -- When a blind transfer is initiated
+;  ATTENDEDTRANSFER -- When an attended transfer is initiated
+;  TRANSFER         -- Generic transfer initiated; not used yet...?
+;  HOOKFLASH        -- So far, when a hookflash event occurs on a DAHDI
+;                      interface
+;  USER_EVENT       -- Triggered from the dialplan, and has a name given by the
+;                      user
+;
+; Default value: none
+;                (Track no events)
+
+events=APP_START,CHAN_START,CHAN_END,ANSWER,HANGUP,BRIDGE_START,BRIDGE_END
+
+; Date Format
+;
+; Use the 'dateformat' keyword to specify the date format used when CEL events
+; are raised.
+;
+; Accepted values: A strftime format string (see man strftime)
+;
+; Example: "%F %T"
+;  -> This gives the date and time in the format "2009-06-23 17:02:35"
+;
+; If this option is not specified, the default format is "<seconds>.<microseconds>"
+; since epoch.  The microseconds field will always be 6 digits in length, meaning it
+; may have leading zeros.
+;
+;dateformat = %F %T
+
+;
+; Asterisk Manager Interface (AMI) CEL Backend
+;
+
+[manager]
+
+; AMI Backend Activation
+;
+; Use the 'enable' keyword to turn CEL logging to the Asterisk Manager Interface
+; on or off.
+;
+; Accepted values: yes and no
+; Default value:   no
+
+;enabled=yes
