That new feature has not been tested yet neither with Telefonica's server nor
in liblinphone tester. That one does not still work because the LinphoneCore
instance simulating the conference server does not handle REFER with BYE requests.
Add a property to LinphoneCalls storing the reference
to the conference in which the call is part of. That
property is NULL if the call is part of no conference
That commit also add some documentation on several
functions
