The contents of CMOS on boot can describe some aspects of
the system configuration. For example, the size of memory
available to qemu/kvm.

* Only SEC is uncompressed now
* The MAIN FV with PEI & DXE can easily shrink and grow as needed
* The final output will now be OVMF.Fv rather than OVMF.fd
* The final output size will be a multiple of 64kb

OVMF utilizes EmuVariableFvbRuntimeDxe to provide an emulated
variable firmware volume block device for non-volatile variables.
This allows the VariableRuntimeDxe and FaultTolerantWriteDxe
to function without a real non-volatile backing store.

Make use of EMU Variable driver's PcdEmuVariableNvStoreReserved to allow
NV variables to persist a VM system reset. The contents of the NV variables
will still be lost when the VM is shut down, but they appear to persist
when the efi shell reset command is run. (Tested with QEMU 0.10.0.)
