Comment (by meejah):

 Testing against master (9af76a9) for existing control-port using software,
 this enhancement changes the "type" given by `getinfo config/names` from
 `LineList` to `Dependent` (which is also a spelling change from last
 release where it's `Dependant`).

 Prior to now, the only thing which had the `Virtual` +
 `Dependent`/`Dependant` things was the hidden-service stuff (and only
 because order matters, according to control-spec).

 Ideally, `SocksPort` et al. would still report their type as `LineList`.
 Also, my understanding of the use of `Virtual` + `Dependent` was for
 options whose order matters. This doesn't appear to be the case here
 (unless I'm missing something?). If these *do* need to be Virtual then
 control-spec should be updated.

 txtorcon uses `getinfo config/names` to programmatically decide which
 parsers to use for options; I don't know if other control-port software
 does as well. I could of course just special-case all these new ones
 (which is the only solution currently) but the change from `LineList` ->
 `Dependant` seems unnecessary for this feature.

 (As an aside, I would personally like to see `Virtual` + `Dependent` go
 away entirely as it's the only special-case weird order-dependent thing in
 SETCONF).
