This systemcall was deprecated early in the 2.6 series
as it was replaced by an in-kernel cache which was refilled
using an upcall. All communication to kernel is now through
the nfsd filesystem.
The nfsctl systemcall itself was removed in 3.1.
It is unlikely to have been used for over a decade.
To remove all uses for the nfsctl systemcall, and call code that only
runs when "new_cache" is false. We now assume "new_cache" is always
true.
This allows the removal of several files as well as assorted functions.

The /var/lib/nfs/rmtab file delineates fields in each of its lines
with a ":". The first field contains the IP address of a client, in
presentation format. IPv6 presentation format addresses contain
colons, which screws up the field delineation of rmtab.
Use a simple simple scheme to convert the colons in incoming client
names to some other character, and then convert them back when the
rmtab file is read.

If we're using the new caching interface the rmtab will be ignored by
exportfs so there is no need to fdatasync. This improves mountd performance.
