    OpenBSD: don't use AFS_GLOBAL_SUNLOCK on single processor system
    
    Put back the header directives that only turns on AFS_GLOBAL_SUNLOCK
    when compiling for multiprocessors system. When enabled on a single
    processor OpenBSD system, it is possible to put the entire system
    into a lengthy (minutes) lock state when performing multiple AFS
    activities. The system behaves MUCH better when AFS_GLOBAL_SUNLOCK
    is not set (no problems encopuntered). This whole locking mechanism
    needs a bit more examination on OpenBSD before this is useful in
    single processor mode.
