the option to HSLayer2Guards. It also now applies to all HS circuit

Sounds good. Took a look at the code and looks reasonable. WRT to:
{{{
* XXX: Hrmm.. HSDIR fetches might be CIRCUIT_PURPOSE_C_GENRAL.. How do

}}}
perhaps you can check for the `rend_data` field on the `origin_circuit_t`
if you have access to that.
