Fix the test for a NetScaler trace file.
When testing the signature field against a given version's signature:
we require that the signature field's size (size, not C
null-terminated string length) be at least the size of the
signature string (otherwise, it can't possibly match);
we check to make sure that the first N bytes of the signature
field, where N is the size of the version's signature string
(not including any terminating '\0' in that string), match the
version's signature string.
I.e., we require that the version's signature string is a prefix of the
signature string in the file.
This does not require that the signature string in the file be
null-terminated.
It also doesn't allow the file's signature string to be a substring of
the version's signature string, as that's *NOT* sufficient to identify
the file as a NetScaler trace file, especially if we forcibly
null-terminate the file's signature string and we trucate it to be
zero-length, as, in that case, it's *always* a prefix of the version's
signature string, and the file is incorrectly identified as a NetScaler
trace file.
(While we're at it, we make the nspm_signature_isvXXX() routines return
true if it *is* and false if it *isn't*, rather than the reverse; having
a routine with a name containing "is", and not "isnt", return true if it
*isn't* is confusing.)
