Pass down max_size parameter to cli_samr_query_dispinfo() instead of

Browse Source 
using a hardcoded value later on.

Added a helper function that returns the observed values for
max_entries and max_size for each cli_samr_query_dispinfo() call.
These values were obtained from watching the NT4 user manager
application with ethereal and are the only ones that can enumerate a
60k user domain reliably under Windows 2000.
