842d333 by Guy Harris (guy@xxxxxxxxxxxx):

    Fix up the checks in nspm_signature_version().
    
    Move the read out of nspm_signature_version(), to make it a bit clearer
    what file I/O we do in the open process; have nspm_signature_version()
    just look for a signature in a single page.
    
    In the loop in nspm_signature_version(), make sure we have enough of the
    record header to look at the type and length fields in that header
    before looking at them and, when we can look at them, make sure the
    length of the record 1) fits in what remains of the page we're looking
    at and 2) is big enough to be the length of a signature record.
