Just unref the connection instead of explicitly closing it (thanks, Rob
McQueen).
Add a commented-out unregister_object_path call: unfortunately, when we
call it, libdbus segfaults. But if we don't unregister the path, we
can't register it again. So regenerations are broken either way, but a
little less violently like this.
Add replies, which use standard X error values, to the two currently-supported
input configuration requests.
Document the D-BUS API we use.
Make sure we free everything when we encounter an error.
Add a _source option to all incoming requests, noting that it came from a
client.
Reject all requests to add a device where an option name contains an
underscore.
Fix a small race whereby you could remove a device while events from it
were still in the queue, by calling ProcessInputEvents immediately before
RemoveDevice, to (hopefully) flush the event queue.
Also move LookupDeviceIntRec into the DIX, and add InputOption type, and
NewInputDeviceRequest prototype (DIX requests DDX to add a device). Does not
link without an implemented NIDR.
