* g10.c (main): Add --multifile as an alias to turn --encrypt into

--encrypt-files (plus --verify-files, --decrypt-files).

* encode.c (use_mdc), g10.c (main): Use RFC1991 and RFC2440 directly to
check for MDC usability.  Do not set the force_mdc or disable_mdc flags
since there is no point any longer.
