Attended call transfer implementation. The changes involves:

- Added support for SIP Replaces extension (RFC 3891)
- Added pjsua_call_xfer_replaces() to perform attended call
  transfer.
- PJSUA checks and process Replaces header in incoming calls
- Added pjsip_ua_find_dialog() API.
- Added pjsip_endpt_has_capability() API.
- Added pjsip_endpt_send_response2() API.
- etc.
