Allow large numbers of counters to be retrieved using one invocation of the NRPE daemon

[lovedada]

We tried to retrieve about 20 counters in one hit using the NRPE daemon and quickly ran into the 1024 byte packet size limit, see last line of the output below.

It'd be good to be able to retrieve all our counters in one hit as that would make it possible for NSClient to batch up the windows calls and avoid the 1 second sleep for every counter (separate ticket raised for this).
