A property can only be deleted if any of the following is true:
- if a property is deletable and all handlers return Success.
- if a property is non-deleteable and the all handlers return Success AND the
delete request does not come from a client (i.e. driver or the server).
A client can never delete a non-deletable property.
We may need more than one handler to deal with a property (e.g. one in the
driver, one in the DIX), so get the handlers into a linked list and call them
one-by-one. This is of course slightly less entertaining than the hilarious
WRAP/UNWRAP game we play in other parts of the server.
XIRegisterPropertyHandler/XIUnregisterPropertyHandler are the interface
drivers/the DIX should use to attach themselves to the device.
XIDeleteAllDeviceProperties destroys everything, including the handlers.
Basically just copied from randr properties, with minor changes only.
Each device supports arbitrary properties that can be modified by clients.
Modifications to the properties are passed to the driver (if applicable) and
can then affect the configuration of the device.
Note that device properties are limited to a specific device. A property set
on a slave device does not migrate to the master.
