Add "init" command to control ENGINE initialization. Call ENGINE_finish on initialized ENGINEs on exit. Reorder shutdown in apps.c: modules should be shut down first. Add test private key loader to openssl ENGINE: this just loads a private key in PEM format. Fix print format for dh length parameter.
