Add support for ./configure --disable-introspection

Sometimes it can be useful to provide an embedded interpreter
where introspection is not permitted.
This includes:

- info commands, procs, channels: only allow exact match, not glob pattern
- info frame: don't include cmd and proc in the returned dict
- info level: only return the command name, not the command arguments
- info body, args, statics: do not allow these to be called
