VirtualBox 3.2.12 -> 4.0.8: "grp" key isn't forwarded to guests (regression?)

[Dmytro Pryanyshnikov]

Hello!

  I've found a layout switch key processing change after VirtualBox
upgrade 3.2.12 -> 4.0.8. I'm using left Win key for keyboard layout
switch on the host:

Option	    "XkbOptions" "grp:lwin_toggle,grp_led:scroll"

Under VirtualBox 3.2.12 I'm able to use this key in guest OSes
(Windows XP, Linux) - it toggles the selected keyboard indicator on
host _and_ is processed by the guest OS. Under VirtualBox 4.0.8 the
same guests don't react on this key strokes, just like VirtualBox
filters them. I can't find anything relevant in the changelog, so IMHO
this behaviour change looks like regression.
