  Log:
  Clean up error handling in libstand filesystem code to be more consistent:
  - bzipfs and gzipfs now properly return errno values directly from their
    read routines rather than returning -1.
  - missing errno values on error returns for the seek routines on almost
    all filesystems were added.
  - fstat() now returns -1 if an error occurs rather than ignoring it.
  - nfs's readdir() routine now reports valid errno values if an error or
    EOF occurs rather than EPERM  (It was just returning 0 for success and
    1 for failure).
  - nullfs used the wrong semantics for every function besides close() and
    seek().  Getting it right for close() appears to be an accident at that.
  - read() for buffered files no longer returns 0 (EOF) if an error occurs,
    but returns -1 instead.
