  util-internal: fix __func__ redefinition (netbsd)
  
  ==> netbsd: In file included from ../listener.c:57:0:
  ==> netbsd: ../util-internal.h:58:0: warning: "__func__" redefined [enabled by default]
  ==> netbsd:  #define __func__ EVENT____func__
  ==> netbsd:  ^
  ==> netbsd: In file included from /usr/include/amd64/types.h:39:0,
  ==> netbsd:                  from /usr/include/sys/types.h:45,
  ==> netbsd:                  from ../listener.c:30:
  ==> netbsd: /usr/include/sys/cdefs.h:394:0: note: this is the location of the previous definition
  ==> netbsd:  #define __func__ __PRETTY_FUNCTION__
