sip: Register log callback function with sofia-sip
sofia-sip allows applications to register a log backend function which will be called every time the library wants to log something. We register such a call-back and make it log using the libosmocore logging framework. The problem is that sofia-sip has its own log level management, and by the time the message hits libosmocore, we don't know which log level we shall use :( Change-Id: Ib269b6b50f9d79bbd13acc43a626834921f05edb Related: OS#3105
