	* dbus/dbus-connection.c
	(_dbus_connection_queue_received_message_link,
	_dbus_connection_message_sent): Add the path to
	the verbose output.
	(_dbus_connection_send_preallocated_and_unlock): Added.  Calls
	_dbus_connection_send_preallocated_unlocked(), updated the
	dispatch status, and unlocks.  Fixes a bug where certain
	situations (like a broken pipe) could cause a Disconnect message
	to not be sent, tricking the bus into thinking a service was still
	there when the process had quit.
	(_dbus_connection_send_preallocated): Call
	_dbus_connection_send_preallocated_and_unlock().
	(_dbus_connection_send_and_unlock): Added.  Calls
	_dbus_connection_send_preallocated_and_unlock().
	(dbus_connection_send): Call _dbus_connection_send_and_unlock().
	(dbus_connection_send_with_reply): Update the dispatch status and
	unlock.

	* mono/Service.cs (~Service): Added.  Removes the filter so that
	we don't get unmanaged code calling back into a GCed delegate.
	(RemoveFilter); Added.
