Gary Larizza 02e85b9651 New str2saltedsha512 function for OS X Passwords
OS X 10.7 introduced salted-SHA512 password hashes as opposed to the
older LANMAN + SHA1 hashes. To assist in generating properly-formatted
password hashes, this commit adds the str2saltedsha512() function which
accepts a single string argument (the password) and returns a
salted-SHA512 password hash which can be fed as the password attribute
of a user resource in OS X 10.7.

Spec tests are also added to ensure that functionality isn't broken with
future commits.

This converts a string to a salted-SHA512 password hash (which is used for
OS X versions >= 10.7). Given any simple string, you will get a hex version
of a salted-SHA512 password hash that can be inserted into your Puppet
manifests as a valid password attribute.
