Subject: md5_gen inconsistencies

Jim -

With all the recent interest in sha1(md5($p)) hashes (did some database
of those leak?), I noticed that md5_gen_preloads.c: md5_gen_IS_VALID()
skips many ex-subformats under x86-64 builds, but those are nevertheless
printed by --subformat=LIST in those builds - this is very confusing to
users.  Perhaps at least fix --subformat=LIST?

And maybe also rename this option to something closer to its current
meaning, like --list-generic-formats?

Also, the braces in md5_gen(...) are annoying, and the reference to
"md5" is wrong for some of them.  Maybe these all should be renamed to
simply gen0 and so on, with no underscore and no braces?  In john.pot,
we could use $gen0$ and so on.

For backwards compatibility, the old names could be recognized in
valid(), though.
