This is a checkin for Issue #311 "CRYPT Storage Scheme Support". This code was contributed externally by java.net user bdamm. The crypt implementation itself was ported from the C-based one OpenSolaris. Since the OpenSolaris code is covered under the CDDL, we're okay to include it in OpenDS, but I've opened issue 1573 to remind us to make sure that we got all of the copyrights right etc.
