DBus requests are received by the public DBus connection, because it
registers the relevant bus name.  My previous patches told PBAP to
listen on a private connection, but DBus doesn't let connections share
bus names, so it needs to listen on the public connection instead.

This adds a little more complexity to the logind callbacks, to avoid
unregistering profiles during shutdown.  It also removes an API I
previously added, which is no longer used and would only encourage the
next person to make the same mistake.

Logind (un)registers callbacks that it calls when the user's state changes.
Callbacks may also be called during (un)registration.
Clients may need to handle those initial/final calls specially.

Pass an argument indicating whether this is being called during
(un)registration, and modify existing callbacks to ignore that argument.

PBAP must not use its own private DBus connection, as it needs to
receive messages sent to the bus name of the public connection.

PBAP must not unregister itself when the program is exiting, as it might
cause a long delay.  Unregistering at exit is redundant anyway, as the
service will be implicitly unregistered when the connection is closed.

But PBAP must unregister itself when the user becomes inactive mid-session,
so systems with multiple users logged in at once can share bluetooth.

Use the public DBus connection instead of a private one,
and explicitly unregister the profile if appropriate.

Thanks Pauli Virtanen for pointing out the exit issue:

This reverts commit 237d818ef294e22be87fba69b3cdd79c75c201e7,
which encouraged the use of private DBus connections.
Doing so caused a bug, so it's better to remove the temptation for now
and re-add it if a legitimate use case is ever found.

This is not going very well in my opinion, it looks like we missed the
opportunity to integrate the logind directly into obc_driver so we
don't have to duplicate code for each coded, so we keep just doing
plugin_init->obc_driver_register/plugin_exit->obc_driver_unregister
and that internally can detect when it shall be registered with the
Bluetoothd, etc, plugin_exit->obc_driver_unregister can actually be
assumed to be exit rather than just D-Bus unregister which happens
when seat is not longer active.

If I understand correctly, you want something like this:

 static struct obc_driver pbap = {
 	.service = "PBAP",
 	.uuid = PBAP_UUID,
 	.target = OBEX_PBAP_UUID,
 	.target_len = OBEX_PBAP_UUID_LEN,
 	.supported_features = pbap_supported_features,
 	.probe = pbap_probe,
 	.remove = pbap_remove,
+ 	.seated = pbap_seated,
+ 	.unseated = pbap_unseated
 };

That's fine, but it sounds like version 2.  Would it be better to get this
bugfix ready to commit first, then talk about architecture in another thread?
I only see a couple of mistakes from bluez test bot (both "mixed declarations
and code"), but the new architecture will take a lot of work and may not be
right first time.  Having a commit with no known bugs will make bisecting
easier, and having a fix out sooner will help users.

As an example of the problems to discuss in version 2 - bluetooth.c uses
obex_transport_driver instead of obc_driver, so the changes would need to go there too.  
Getting that right will take more time and discussion, and could lead to some knock-on
change that adds more again.

Except 2 simple build errors, this allows me to connect the pbap profile.
