Subject: Rename S2K to PBKDF, because that is by far the most common name -
 S2K really is only used by OpenPGP, and largely it was named S2K here because
 the OpenPGP S2K was implemented years before the ones in PKCS #5. We have a
 typedef of PBKDF to S2K, and an inlined get_s2k that calls get_pbkdf for
 source compatability.

There doesn't seem to be any reason to have a forward for the renamed
s2k.h header - to actually use a PBKDF, you'd have to either include
lookup.h and call get_s2k / get_pbkdf, or else include an
algorithm-specific header and use it directly. In either case,
including s2k.h is neither necessary nor sufficient.
