Incomplete prototype

[Dag-Erling Smørgrav]

The prototype for ub_event_get_version() in util/ub_event.h is missing
an argument list.  C11 allows function definitions to have empty
argument lists but not prototypes.  Patch relative to tip of svn tree:

-const char* ub_event_get_version();
+const char* ub_event_get_version(void);
 /** Return the name, system and method for the pluggable event base */
 void ub_get_event_sys(struct ub_event_base*, const char** n, const char** s,
 	const char** m);

The definitions in util/ub_event.c and util/ub_event_pluggable.c don't
have argument lists, which is perfectly fine from the standard's point
of view, although I would have provided one as a matter of principle.

Full list of function definitions with empty argument lists in Unbound:
