vmcb.c due to it being unnecessary
Changes since v1:
- Change a test condition from if it had the vgif feature to if it's
enabled in the vmcb
- Update for the use of C99 bool type
- Added else in vgif init code in vmcb.c

This patch detects and enables Virtual GIF if available. This allows
a nested hypervisor to perform STGIs and CLGIs without having to be
intercepted by host hypervisor.

There was some discussion in the irc channel so I'm not sure if there's
going be another version soon or not. I need to fix the style error I
have with the else anyway.
Thank you for the feedback.
