        src/lib/libssp: Makefile fgets_chk.c gets_chk.c memcpy_chk.c

        src/lib/libssp/ssp: ssp.h stdio.h string.h unistd.h

Log Message:
Add a BSD-licensed re-implementation of the gcc-4.1 libssp.
This adds bounds checking for the following functions:

    memset, fgets, gets, memcpy, memmove, memset, snprintf, sprintf, strcat,
    strcpy, strncat, strncpy, vsnprintf, vsprintf

This functionality is enabled by compiling with:

        gcc -I/usr/include/ssp -D_FORTIFY_SOURCE=<1|2> -lssp

Eventually gcc will provide -ffortify-source or something to automate this
[we hope :-)]
