bugref:8524: Additions/linux: play nicely with distribution-installed Additions
Add a todo to VBoxGuest.cpp regarding VBOXGUEST_IOCTL_CANCEL_ALL_WAITEVENTS.

A todo to enforce the new semantics of VBOXGUEST_IOCTL_CANCEL_ALL_WAITEVENTS
that VBOXGUEST_IOCTL_WAITEVENT may no longer be called in a session after
VBOXGUEST_IOCTL_CANCEL_ALL_WAITEVENTS has been called.

+ *  called.  Change the code to make calls to VBOXGUEST_IOCTL_WAITEVENT made
+ *  after that to return VERR_INTERRUPTED or something appropriate. */
