unused-parameter problems reported by GCC. Add an _U_ tag to label parameters as unused if the function is called through a pointer (so that you can't change its signature by removing parameters) or if there are unused parameters only because the function isn't complete. Add some additional bounds checks the necessity for which was revealed while cleaning up unused-parameter problems. Make some routines static. "lcp_print()", defined in "print-lcp.c", isn't called anywhere - "print-ppp.c" has the code to dissect LCP. Get rid of "print-lcp.c".
