> This branch fixes and extends the x509_extension event, which was never called in the previous implementation. The event now parses the extension into a bro data structure. If supports printing it, it is converted into the openssl ascii output, otherwise a raw hex-dump is output.
> New event syntax:
> event x509_extension(c: connection, is_orig: bool, cert:X509, extension: X509_extension_info)
> Example output for extension:
>   [name=X509v3 Extended Key Usage,
>     short_name=extendedKeyUsage,
>     oid=2.5.29.37,
>     critical=F,
>     value=TLS Web Server Authentication, TLS Web Client Authentication]
>   [name=X509v3 Certificate Policies,
>    short_name=certificatePolicies,
>    oid=2.5.29.32,
>    critical=F,
>    value=Policy: 1.3.6.1.4.1.6449.1.2.1.3.4^J  CPS: https://secure.comodo.com/CPS^J]
