modified become_master() to a state-based system. becoming a master

is now performed in stages: wait for each NetBIOS name to be
successfully registered before proceeding to the next stage.

tied implicit name registration and release (broadcast method) to the
same piece of code as explicit method (via WINS server).

created special_browser_name() function that checks __MSBROWSE__
name: this name is ignored by WINS servers apparently.

fixed likely incompatibility between refresh_my_names() and add_my_names().
(netbios entries were unlikely to be refreshed).

NOTE: none of these changes have been tested. at all.
