We need them for each window, every time a window is allocated. Storing them
in a devPrivate is the wrong thing to do.
This also removes the unused ENTER_LEAVE_SEMAPHORE_ISSET macro.

grab == devgrab anyway, this is a leftover from the time when we had two
different grabs per device (core and XI grab).

Really, this was a bad idea. It's not security, the UI features that would
have been cool (e.g. clicking through windows) aren't implemented anyway, and
there's nothing you can't achieve just by using plain XI anyway.
Requires inputproto 1.9.99.6.
Two corrections
1. the "detail" field has NotifyVirtual, etc., not the "mode" field. This was
a clear bug.
2. don't set/unset the flags for NotifyGrab or NotifyUngrab. Clients are
expected to deal with multiple enter/leave events per window if the mode is
not NotifyNormal.
Testable with TCL menu boxes (such as used in gitk):
tk_optionMenu .menu globVar Val1 Val2 Val3 ValJunk
pack .menu

This fixes a severe issue - when the client died the event mask didn't get
unregistered and a future event would dereference dangling pointers. By
storing the event masks in the resource system we can free them when the
client dies.
Dereferencing into dev->valuator could crash the server, although it looks
like I could only reproduce this by having a keyboard send an event after it
was created and the WM was still replaying. Or so.
device->button->down used to be a 32-byte bitmask with one bit for each
button. This has changed into a 256-byte array, with one byte assigned for
each button. Some of the callers were still using this array as a bitmask
however, this is fixed with this patch.

RealizeCursor should be called when the cursor is allocated. However, when the
root cursor is allocated, no devices exist yet, and thus RealizeCursor is
never called. This may lead to segfaults lateron in DDXes like Xnest that
actually need to do something for each cursor, and lateron rely on that
DDX-specific data for each cursor has been initialized.
Instead of a simple counter, use bits to keep track of which device is where
etc. When device enters a window (or sets focus), the bit matching the device
is set, when it leaves again, it is unset. If there are 0 bits set, then
Leave/Enter/Focus events may be sent to the client.
Same theory as before, but this should get around the insanity with
Grab/Ungrab special cases. Those cases are basically untested though.
If an pointer event is being processed during a device grab, don't deliver it
to the focus window, even if the device has a focus class. Reason being that
some pointers may have a focus class, thus killing drag-and-drop.
Add Prox events to the if-clauses with the other events
that are usually sent from the input devices.
Ensure that the event deliverers won't try to deliver
events of type '0' (some extended events doesn't have
an equivalent core-type)

The latter is used to increase the amount of allocated memory for the event
list. This will be needed for ClassesChangedEvents that can be of more or less
arbitrary size (larger than 32 anyway).
Rather than letting the DDX allocate the events, allocate them once in the DIX
and just pass it around when needed.
DDX should call GetEventList() to obtain this list and then pass it into
Get{Pointer|Keyboard}Events.
