Log Message:
Make dsniff and dsniff-nox11 build on NetBSD-current:
* In dsniff-nox11/Makefile, add a post-configure target to move
  missing/sys/queue.h out of the way if the configure script
  found a real sys/queue.h.
* Add patches to #include <string.h> in some files where I noticed warnings.

Bump PKGREVISION for both dsniff and dsniff-nox11.
