Very basic file-analyzer for x509 certificates. Mostly ripped from
the ssl-analyzer and the topic/bernhard/x509 branch.

Simply prints information about the encountered certificates (I have
not yet my mind up, what I will log...).

Next step: extensions...
parse out extension. One event for general extensions (just returns the
openssl-parsed string-value), one event for basicconstraints (is a certificate
a CA or not) and one event for subject-alternative-names (only DNS parts).
rip out x509 code from ssl analyzer. Note that since at the moment
the file analyzer does not yet re-populate the info record that
means quite a lot of information is simply not available.
