  Log:
  HAMMER 64/Many: NFS, cross-device links, synctid
  
  * Check for cross-device links and cross-PFS links in the link and
    rename code.
  
  * Update a directory's mtime when a file is created or deleted within it.
    (good idea anyway, also allows NFS clients to properly invalidate their
    directory caches).
  
  * Only lock the PFS sync-end-tid field when the HAMMER_PFSD_SLAVE flag is
    not set.
  
  * Clear ocp->dip->objid_cache when cleaning out the object cache.
  
  * PFS softlinks in the form @@PFS%05d are auto-expanded by HAMMER's
    readlink() to include a snapshot transaction id.  Adjust getattr
    to properly set va_size (aka stat->st_size) to the length of the
    expanded version.  This fixes NFS confusion and allows PFS's to be
    mounted via their softlinks.
  
  * Fix another issue where the synctid ioctl would still sometimes stall
    until the next filesystem sync.
