add generic keepalive system and implement it in sofia to send MESSAGE or INFO packets in-dialog at specified interval. Adds app: enable_keepalive 0|<seconds> This app can be run in the dialplan or with execute_on_* type variables for B-legs. Adds sofia param: keepalive-method : defaults to MESSAGE can also be "INFO" This param sets which SIP method to use.
