Code maintenance style
STYLE: rm explicit void for parameterless function

Functions that take no parameters do not need an
explicit void designation.  Removing these unnecessary
designations provides more consistent code style and
allows for easier regular expression code
maintenance.

%s/( *void *) *const *;/() const;/g
%s/( *void *) *;/();/g
