There's devices (e.g. some barcode readers) that have axes but no buttons.
When such a device sends a motion event, the valuator and button class is
copied into the master pointer (i.e. removing the button class).
So we need a couple of extra sanity checks for the button class to exist.

There's no need for internal events to be a struct with a single nested
union, we might as well make the union itself the InternalEvent.

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).
Add a proper access mode, and reverse the logic of the return value.
Zero ("Success") is returned on success from the hook calls.

This also means that wherever we passed in (mskidx = 0), we now need to pass

The masks were originally designed to generically handle event masks for
extensions. Since all that is in-server anyway, it's much better writing
custom event masks for those extensions that need it and not providing a
unified mechanism.
XI2 needs more than the current implementation, which is already too complex
for most other extensions. good riddance.

dixLookupResource attempted to automatically detect whether the caller
wanted a lookup by-type or by-class, unfortunately, it guessed wrong for
RT_NONE. Instead of trying to make the guess better, this patch just reverts
the unification and creates separate functions for each operation.

Note that we're only partially switched to internal events. The event in the

events in syncEvents are InternalEvents only now.

If the MD's lastSlave was a devices with custom axes ranges, then a
WarpPointer would position the cursor at the wrong location. A WarpPointer
request provides screen coordinates and these coordinates were scaled to the
device range before warping.
This patch consists of two parts:
1) in the WarpPointer handling, get the lastSlave and post the event through
this device.
2) assume that WarpPointer coordinates are always in screen coordinates and
scale them to device coordinates in GPE before continuing. Note that this
breaks device-coordinate based XWarpDevicePointer calls (for which the spec
isn't nailed down yet anyway) until a better solution is found.
