    audit: Make audit operations threadsafe
    
    In order to prevent races between audit operations and shutdown, extend
    audit_lock protection to all audit operations.  Move the audit_lock
    protection inside multi_send_msg to make it more consistent with the
    other usage.
    
    In addition, as needed, extend audit_lock protection to various audit
    global variables.
    
    To avoid needing to hold audit_lock while calling
    audit_user_check_global.islocal(), require osi_audit_set_user_check()
    callers to not free the provided values after calling
    osi_audit_set_user_check(). All existing callers just call
    osi_audit_set_user_check() once, early during server startup, so this
    requirement does not affect any existing code.
    
    Finally, consolidate the AFS_AIX32_ENV stanzas in osi_audit_internal.
