client: add option to print all sources

Browse Source 
Add -a option to the sources and sourcestats commands to print all
sources, including those that don't have a resolved address yet. By
default, only sources that have a real address are printed for
compatibility. Remove the "210 Number of sources" messages to avoid
confusion. Also, modify the ntpdata command to always print only sources
with a resolved address.
