Paolo Bonzini 87ccb7dbb2 kvm: selftests: actually use all of lib/vmx.c 
The allocation of the VMXON and VMCS is currently done twice, in
lib/vmx.c and in vmx_tsc_adjust_test.c.  Reorganize the code to
provide a cleaner and easier to use API to the tests.  lib/vmx.c
now does the complete setup of the VMX data structures, but does not
create the VM or set CPUID.  This has to be done by the caller.

Paolo Bonzini d5edb7f8e7 kvm: selftests: add vmx_tsc_adjust_test 
The test checks the behavior of setting MSR_IA32_TSC in a nested guest,
and the TSC_OFFSET VMCS field in general.  It also introduces the testing
infrastructure for Intel nested virtualization.
