This also installs symlinks from "zeek" and "bro-config" to a wrapper
script that prints a deprecation warning.
The btests pass, but this is still WIP. broctl renaming is still
missing.
#239
The event now really returns the extension. If openssl supports printing
it, it is converted into the openssl ascii output.
The output does not always look pretty because it can contain newlines.
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]
