I think it's difficult to split this one into meaningful patches, reason being that
'tor-hidden-service-type' can't be used alone since the record constructor for a
Tor hidden service (hidden-service, which is IMO a "collision prone" name) is not exported.

The fact that it isn't exported also means that the 'hidden-services field from <tor-configuration>
was impossible to configure. Extending 'tor-service-type' was also impossible save for the
(to be deprecated) 'tor-hidden-service' procedure which provisions a 'tor-hidden-service-type'
that is simply a service extension for 'tor-service-type'.

The 'tor-hidden-service' and 'tor-hidden-service-type' are extremely misleading to what will
happen behind the scenes should more than one hidden-service be provisioned (with 'tor-hidden-service').
Since it does so via a 'tor-hidden-service-type' which has its own name, only one of the hidden-services
will get configured, which one = dice roll.

IMO this 'tor-hidden-service-type' shouldn't exist at all and tor-hidden-service can safely be
converted into a simple-service that extends tor-service-type.


Cheers,
Bruno
