res_pjsip.c: Added disable_rport option for pjsip.conf

Currently when the pjsip making an outgoing request, it keep adding the
rport parameter in a request message as a default.

This causes unexpected rport handle at the other end.

Added option for disable this behaviour in the pjsip.conf.

This is a system option, but working as a gloabl option.

+Subject: res_pjsip
+
+Added a new PJSIP system setting called disable_rport.
+Default is no to keep support working as before.
+
+If it is false (default) it adds the 'rport' parameter in the outgoing request message.
+If it is true it does not add the 'rport' parameter in the outgoing request message.
+
+This is a system option, but working as a global option.
