Prepare DSM registry for upcoming changes to LWLock tranche names. A proposed patch would place a limit of NAMEDATALEN-1 (i.e., 63) bytes on the names of dynamically-allocated LWLock tranches, but GetNamedDSA() and GetNamedDSHash() may register tranches with longer names. This commit lowers the maximum DSM registry entry name length to NAMEDATALEN-1 bytes and modifies GetNamedDSHash() to create only one tranche, thereby allowing us to keep the DSM registry's tranche names below NAMEDATALEN bytes.
