I forgot to mention that it's faster than Rafael's due to preserving and
reusing of memory allocation(s) across scrypt computations.  My escrypt,
which I had shared with Rafael, readily had this functionality - it only
needed to be made use of in the format.

And indeed there's OpenMP support, which somehow was missing in Rafael's
format.

I've now attached a newer revision of it.  The only changes since the
revision I posted some minutes ago are to escrypt/crypto_scrypt-sse.c
(more complete removal of the experimental defeat_tmto feature, which we
don't need in JtR yet) and escrypt/Makefile.
