One more from @stevesmoot. The record_fields() BIF produced "enum" as
type_name for fields of type enum.
Extend container_type_name() to append the actual name of the enum.
This is changing the format and may break consumers, but those are
likely in a category that are happy to adapt. Not having the actual
enum name available wasn't very helpful.
We could alternatively render only the actual type_name without the
prefixed "enum", but that isn't how it's done for record types currently
and it would make it more difficult to decide which subsequent BIFs to
use for further introspection, like enum_names().
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.
