channels/pjsip/dialplan_functions: Add an option for extracting the SIP call-id

This patch adds a new option to the CHANNEL function that allows for the
extraction of the SIP call-id. It is used in conjunction with the 'pjsip'
option, and will return the Call-ID of the INVITE request that established
the PJSIP channel.

* The CHANNEL function, when used on a PJSIP channel, now exposes a 'call-id'
extraction option when using with the 'pjsip' signalling option. It will
return the SIP Call-ID associated with the INVITE request that established
the PJSIP channel.
