V1 of this series didn't update the usage() message for mountd,
and omited the required ':' after the 'T' sort-option.  This 
series fixes those two omissions.

Original series comment:

When NFSv3 is used mountd provides logs of successful and failed mount
attempts which can be used for auditing.
When NFSv4 is used there are no such logs as NFSv4 does not have a
distinct "mount" request.

However mountd still knows about which filesysytems are being accessed
from which clients, and can actually provide more reliable logs than it
currently does, though they must be more verbose - with periodic "is
being accessed" message replacing a single "was mounted" message.

This series adds support for that logging, and adds some related
improvements to make the logs as useful as possible.

      mountd: reject unknown client IP when !use_ipaddr.
      mountd: Don't proactively add export info when fh info is requested.
      mountd: add logging for authentication results for accesses.
      mountd: add --cache-use-ipaddr option to force use_ipaddr
      mountd: make default ttl settable by option
