Don't do too much work in the finalizer - in particular, there's no
need to send RemoveMatch() messages to the bus daemon since we're
going to sever the connection and the bus will garbage collect
anyway. In this case it crashed the process.
Also add a test case that checks that the appropriate GDestroyNotify
callbacks are called when unreffing a connection with either 1)
exported objects; 2) signal subscriptions or 3) filter functions
.. yes, ideally apps would unregister such callbacks before giving up
their ref but that's not how things work :-)

Otherwise e.g. setuid root processes can't connect to the system
bus. This was discovered when porting PolicyKit's pkexec(1) command to
a PolicyKit library using GDBus.

You can drop a key-file in the schema directory that looks like:
[org.gtk.Example]
key='value'
to override the default value of 'key' in schema 'org.gtk.Example'.
This reverts commit 0201a81f04 and adds
locks in the right place.
As this file is a public header (see last commit), we cannot just remove
functions from it.
gobjectnotifyqueue.c is a public header, so we cannot remove files from
it. (Yes you read that right, this .c file is a public header. See your
installation directory.)
Adds locking around object property change notification handling. The
notifications are only emitted after all threads have called
g_object_thaw_notify().

- Make GCredentials instance and class structures private so it can't
be subclassed and we don't have to worry about ABI compat
issues. This also allows us to get rid of the GCredentialsPrivate
struct.
- Add a GCredentialsType enumeration that is used whenever exchanging
pointers with the user. This allows us to support OSes with
multiple native credential types. In particular, it allows
supporting OSes where the native credential evolves or even changes
over time.
- Add g_socket_get_credentials() method.
- Add tests for g_socket_get_credentials(). Right now this is in the
GDBus peer-to-peer test case but we can change that later.
- Move GTcpConnection into a separate gtk-doc page as was already
half-done with GUnixConnection. Also finish the GUnixConnection
move and ensure send_credentials() and receive_credentials()
methods are in the docs. Also nuke comment about GTcpConnection
being empty compared to its superclass.

Without this fix, we'd sometimes run code after stop() and finalize()
to handle incoming requests. This was observed in the gdbus-peer test
case occasionally crashing:
$ ./gdbus-peer
/gdbus/peer-to-peer: OK
/gdbus/delayed-message-processing: OK
/gdbus/nonce-tcp:
GLib-GObject-WARNING **: invalid uninstantiatable type `(null)' in cast to `GDBusServer'
aborting...

This allows sending and receiving D-Bus messages with instances of the
'h' D-Bus type. Unlike libdbus-1's dbus_message_iter_get_basic()
method, g_variant_get_handle() does not return a duplicated unix file
descriptor (that must be closed with close(2)) - instead, it returns
an index that can be used to get/dup the file descriptor from a
GUnixFDList object that can be obtained from the GDBusMessage object.

Until after we include the glib stuff, so that we have G_OS_UNIX
defined.
For some reason <stdlib.h> pulls in <sys/wait.h> on Fedora so this
wasn't a problem, but many others have reported the issue.
This is preferable to the current magical solution whereby the serial
is only rewritten if non-zero. In particular, it makes it easier to
send the same message on multiple connections without having to reset
the serial number.
