Remove LACOUNT and LACCESSOR and migrate the records immediately.

This concept didnt work out and it is really just as expensive as a full migration
anyway, without the benefit of caching the data for subsequence accesses.

Now, migrate the records immediately on first access.
This will be combined with a "cheap vacuum-lite" for special empty records to
prevent growth of databases.

Later extensions to mimic read-only behaviour of records will include proper shared read-only locking of database records, making the laccessor/lacount read-only access to the data obsolete anyway.

By removing this special case and handling of lacount laccessor makes the codapath where shared read-only locking will be be implemented simpler, and frees up space in the ctdb_ltdb header for use by vacuuming flags as well as read-only locking flags.

When we are no longer the natgw master, dont put the natgw ip on loopback.
We put the ip on loopback just to make sure we would still interoperate with
non-standard configurations on unix-KDC, that are configured to verify the optional
HostAddresses field.
This is not required for AD, since AD does not use this field, and is replaced in
unix land with other/better mechanisms than this "dodgy" check.

This makes it "easier" for applications that have bound to the natgw address
to detect a socket problem and try to reconnect/recover if the ip address
is completely missing from the system.

At the same time, use the winbind specific hook that exists to explicitely tell winbindd : this address is gone, so if you have bound to it, this is a good time to close and rebind your socket.

60.nfs only fails or warns after 10 consecutive nfsd/statd failures.

avoid dirtying the logs or marking a node unhealthy because of them,
unless they are excessive.

For these 2 cases we use the existing fail counting code but hack a
temporary service_name in a subshell to allow separate fail counts.

We also update ctdb_check_rpc() so that it captures the error output
from rpcinfo and we add a message including the service name to the
beginning.  The error is printed to stdout but is also stored in
ctdb_check_rpc_out to allow it to be conditionally used by the caller.
This function also now returns non-zero rather than exiting on
failure.

Other direct rpcinfo calls are relaced by called to ctdb_check_rpc()
for consistency.

Option handling code for service restarts is cleaned up so that fits
in 80 columns.  A more informative restart messageis now used in all
cases, printing the exact command being used to start a service.
