    libc: Add stack protector support back
    
    Based on regressions indicated by dports bulk build (< 10), it appears
    that the deactivated stack_protector.c code was used with static stack
    protection (e.g. -lssp_nonshared).
    
    FreeBSD moved the file to its own area less than a month ago, which is
    why I thought it had been removed.  The plan is to put all security
    related code in the same area, so I'm going to follow suit.  While here,
    remove the stack_smash_handler, which I believe is obsolete, and reduce
    differences with FreeBSD.
