InternalEvents shouldn't be used anywhere outside the X server itself. Split
up into events.h for opaque typedefs for the events needed by various
headers and eventstr.h for the actual struct definitions.
eventstr.h must only be included by code that requires internal events and
is not part of the SDK.

Master devices provide the union of all attached slave devices' buttons,
i.e. the number of buttons on the master device is always the number of
buttons of the slave device with the highest number of buttons. When slaves
are attached or detached, the master device adjusts the button number to
reflect the new buttons.
On a slave switch, this slave's button labels are copied into the master (up
to slave->num_buttons). The remaining button labels (if any) stay as they
are. Thus, if any of the higher buttons is still pressed, it reflects the
label of the last pressed device that provided this button.
If two devices press the same button and it is differently labelled the last
pressed one will be reflected in the master device.

Copying all classes into the master device has drawbacks for hybrid devices
(devices that are both mice and keyboards). If such a device posts an event,
it's key classes are moved into the VCP. The key event itself is unaffected
by keyboard grabs and the like.
Partial class copying copies depending on the event and copies the classes
into the right master device (i.e. the VCK for key events, the VCP for
pointer events).

ChangeDeviceId would actually overwrite the flags field if deviceid wasn't
present. Aside from the event of course not telling which device generated
it in the first place.

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.

Best to FatalError if a wrong event comes in. At least that forces me to fix
it really quickly.

This is the event we want to feed into the EQ and process on the way through.
Only applies for input events for now.
