rangecheck.h - pointer range checking

       rangecheck.h  provides  several  routines for range checking pointers.  These routines are meant for code
       that has to validate the syntax and semantics of buffers coming in from untrusted sources (like a network
       connection or an input file).

       The routines all return 0 on error, or 1 if the pointers were in range.
