The protocol allows for 16 bit device ids, but the implementation doesn't
yet. We need to break the input ABI once more to shift the DeviceIntRec's
CARD8 to a CARD16, along with some changes in the privates.
Once that is done, revert this patch.

isMaster is not enough as long as we differ between master pointers and
keyboard. With flexible device classes, the usual checks for whether a
master device is a pointer (currently check for ->button, ->valuators or
->key) do not work as an SD may post an event through a master and mess this
check up.
Example, a device with valuators but no buttons would remove the button
class from the VCP and thus result in the
IsPointerDevice(inputInfo.pointer) == FALSE.
This will become worse in the future when new device classes are introduced
that aren't provided in the current system (e.g. a switch class).
This patch replaces isMaster with "type", one of SLAVE, MASTER_POINTER and
MASTER_KEYBOARD. All checks for dev->isMaster are replaced with an
IsMaster(dev).
All XI2 requests have XI prefixes.

ChangeDeviceCursor

A grep on xorg/* revealed there's no consumer of this define.
Quote Alan Coopersmith:
"The consumer was in past versions of the headers now located
in proto/x11proto - for instance, in X11R6.0's xc/include/Xproto.h,
all the event definitions were only available if NEED_EVENTS were
defined, and all the reply definitions required NEED_REPLIES.
Looks like Xproto.h dropped them by X11R6.3, which didn't have
the #ifdef's anymore, so these are truly ancient now."

The window ID includes the client ID anyway, so we might as well just look up
the client directly instead of trying to get the window first and the client
from the window.
This also fixes a possible issue with XACE. If the client had permission to
write on the client but not on the window, the previous approach would have
failed.
All the rest of XI uses rc and returns rc in case of error, so make
mpx-related stuff comply. This stops the rest of XI sending the error
manually.
This is just a cosmetic change to be in line with the rest.
We need this for clients that need to set the ClientPointer but don't have a
window on display yet. If used, it will set the device as the ClientPointer
for the requesting client.
