camel_service_get_settings() is now camel_service_ref_settings()
and it returns a new CamelSettings reference which the caller must
release with g_object_unref().
These functions now return new references:
camel_session_add_service()
camel_session_list_services()
These functions have been renamed and also return new references:
camel_session_get_service() -> camel_session_ref_service()
camel_session_get_service_by_url() -> camel_session_ref_service_by_url()
em_utils_connect_service_sync() and em_utils_disconnect_service_sync()
are no longer needed. CamelService itself now effectively does what
these functions were doing.
These libraries are bound for E-D-S so they live at the lowest layer of
Evolution for now -- even libeutil can link to them (but please don't).
This is the first step toward moving mail handing to a D-Bus service.
