* keygen.c (keygen_set_std_prefs, add_feature_mdc): Use "mdc" and "no-mdc"

Browse source 
in the prefs string to allow switching on and off the MDC feature.  This
is needed to properly export a key from GnuPG for use on PGP which does
not support MDC - without this, MDC-capable implementations will still try
and generate MDCs which will break PGP.

* keygen.c (keygen_get_std_prefs): Show "[mdc]" in prefs string if it is
enabled.

* options.h, g10.c (main), cipher.c (write_header), keygen.c
(keygen_set_std_prefs): For consistency, allow the user to specify
mdc/no-mdc in the --personal-preference-list.  If disabled, it acts just
like --disable-mdc.
