[Jack-Devel] RFC: fix for missing port registration notifications when switching master

The issue was reported in #213 (second issue/patch):

jackdbus' internal graph representation is not properly kept in sync
with the engine's graph. In particular: ports are not properly removed
From the connection list when a client goes away; and ports
re-appearing after a "switch-master" are not being updated (Patch
2/2).

I think the proposed patch is wrong because AFAIK graph reorder is only
for ports present upon client activation. All following port
(un)registrations must cause the port registration callback to be
called. The proposed changeset [1] adds notification calls in the
Attach()/Detach() methods. The changeset is commited to a dedicated
branch [2]. The branch is (hopefully) a short living one with a signle
commit, so it makes sense to commit it directly to svn trunk (after
eventually rebasing it, of the svn trunk moved).

Robin, I'd be glad if you can test & report whether my fix works for
you.
