  * fix the Windows cache manager to prevent it from replacing the
    rx_connection object associated with the cm_conn_t object on each
    and every operation if "fs crypt" was set.  This explains the
    dramatic performance difference when crypt is used vs clear.
    The problem: 'cryptall', a boolean flag indicating whether or not
    "fs crypt" is set, was being compared to the rx_connection
    cryptlevel which is either rxkad_clear:0 or rxkad_crypt:2.
    1 != 2 and therefore the rx_connection was always destroyed
    and replaced on each and every operation.

    Lock the cm_conn_t object around every call to RXAFS_xxxx functions.
    It is not safe for the cm_conn_t object to not be locked because
    rx_DestroyConnection might be called from another thread if:
        - the user's tokens have changed or expired
        - the crypt mode has changed

  * Modify cm_Lookup to evaluate a list of possible values for @sys
    instead of just a single entry.  Re-write cm_ExpandSysname and
    add cm_LookupInternal.

  * Reformat affected files

  * Add cache file name to cache creation errors
