Build time configuration for startup scripts and modules. This addresses multiple issues: * Issue #63: initrd is build fresh each time, so tracked files do not matter. * Issue #144: build time configuration * Issue #123: allows us to customize the startup experience * Issue #122: manual start-xen will go away * Issue #25: tpmtotp PCRs are updated after reading the secret * Issue #16: insmod now meaures modules
