This is how the crash can be triggered with only two clients on the system:
Client A: (already running)
Client B: Connect
Client B: CreateGlyphSet(depthN)
Client A: Disconnect
Server: free globalGlyphs(depthN)
Client B: AddGlyphs(depthN)
Server: SEGV
This crash was introduced with the FindGlyphsByHash function
in 516b96387b. Before that revision,
ResizeGlyphSet was always called before FindGlyphRef, which would
re-create globalGlyphs(depthN) if necessary.

Make sure the reference count of the new cursor is increased before the old
one is decreased, otherwise bad things will happen if they're one and the

A client requesting a GrabModeSync button grab, owner-events true, with only
the ButtonRelease mask set would never receive the press event even if the
grab window had the ButtonPress mask set.
The protocol requires that if owner-events is true, then the delivery mask
is the combination of the grab mask + the window event mask.

The problem is that the xf86_use_hw_cursor(_argb) functions may get this
correctly now, some drivers will replace these generic versions with their
own functions. It is pretty insane to expect them to do reference counting
of the cursor (as an example, look at driver/xf86-video-vmware to see how
that looks like as a workaround). There are even places in xserver itself
which replace these two functions.
The segfaults if no reference counting is done are caused because the
reference count of the cursor reached zero, hence the cursor was freed,
however xf86CursorEnableDisableFBAccess() brought it back to life from
the dead (from the SavedCursor).
This patch hence adds reference counting in xf86CursorSetCursor. As per Michel
Daenzer's suggestion, also free the cursor upon xf86CursorCloseScreen.
In theory with this it should be possible to remove the reference
counting in the UseHwCursor functions I think, though it should also be
safe to keep them.
