Two components to the lcd build now:
-- arch/x86/lcd/Makefile: for building x86 lcd code
-- virt/lcd/Makefile: for building arch-indep lcd code

Modified the build system just slightly for a cleaner
build:
-- virt/ directory treated like ipc/, usr/, etc. directories
-- added Kconfig and Makefile to virt/, mirroring drivers/
-- updated top-level Makefile to include virt/ as vmlinux
   directory / dependency, so build system will recur into
   virt/
-- updated arch/x86/Kconfig to include virt/Kconfig, so it
   will be included as a menu item
-- updated arch/x86/Kbuild to include arch/x86/lcd/

Removed old capabilities code in cap/.

Removed lcd syscall.

Temporarily turned off build for drivers/lcd.

Fixed most bugs in lcd-vmx (still need to do lcd_vmx_exit).
-- minor naming issues in lcd-vmx.h
-- straight copy over of vmx_disable_intercepts_for_msr,
   but with more doc
-- removed VMX_EPT_INDIVIDUAL_ADDR macro from vmx.h (where
   did this come from? it's not documented in the intel manual,
   nor is it used in kvm)
