Fix incorrect password truncation in bcrypt password hashing.

The 56 char bound is bogus; Blowfish itself allows at most 448 bits
in the key schedule, but Bcrypt's modification allows up to 72 chars
for the password. Bug pointed out by Solar Designer.

Also reject work factors 0...3 since all other extant bcrypt
implementations require at least work factor 4.
Adds more bcrypt tests generated by crypt_bcrypt and OpenBSD's version.
