Message:

bugref:8533: Additions/x11: fully support VMSVGA
Add VbglR3AcquireGuestCaps() to the R3 guest library.

This change creates a guest library wrapper for the
VBOXGUEST_IOCTL_GUEST_CAPS_ACQUIRE VBoxGuest driver IoCtl which was added to
allow several instances of VBoxTray to run at once for different users in
Windows guests, but only one at a given time to receive display change and
seamless notifications. VBoxClient --vmsvga can use this to prevent the
privileged kernel mode-setting daemon version and the X11 client version
listening for display change notifications at the same time.
