Fixes#6013.
This commit fixes the Tor healthcheck that would previously fail if
there were multiple hidden service registered.
In the controller, we only need to know that our service is contained in
the list of active services. But we can't do a string equality check
since there might be multiple services, comma separated.
A new method, Reconnect, is added to tor controller which can be used to
reset the current connection. This will be later used in healthcheck to
help us reset the connection to Tor Daemon.
This commit adds a new response reader which replaces the old
textproto.Reader.ReadResponse. The older reader cannot handle the case
when the reply from Tor server contains a data reply line, which uses
the symbol "+" to signal such a case.
This commit adds a new method to call DEL_ONION when lnd is shutting
down. Tor controller will now be aware of the active serviceID and
removes the service upon shutdown.
If we use a chain backend that only understands IP addresses (like
Neutrino for example), we need to turn any Onion v2 host addresses into
a fake IPv6 representation, otherwise it would be resolved incorrectly.
To do this, we use the same fake IPv6 address format that bitcoind and
btcd use internally to represent Onion v2 hidden service addresses.
This provides users an alternative over the SAFECOOKIE authentication
method, which may not be as useful if users are connecting to a remote
Tor sevrer due to lnd not being able to retrieve the cookie file.
In this commit, we modify the AddOnionConfig struct to include an
abstract OnionStore, which will be responsible for storing all relevant
information of an onion service. We also add a file-based implementation
of the interface to maintain the same behavior of storing an onion
service's private key in a file.
In this commit, we extend our Tor controller to also support creating v3
onion services, as they are now supported by the Tor daemon. We also
refactor our existing AddOnion method to take in a config struct that
houses all of the required options to create/restore an onion service.
In this commit, we add our inital implementation of a Tor Controller.
This commit includes the ability for the controller to automatically
signal the Tor daemon to create a v2 onion service. This will be
expanded later on to support creating v3 onion services.
Before allowing the controller to interact with the Tor daemon, the
connection must be authenticated first. This commit includes support for
the SAFECOOKIE authentication method as a sane default.

In this commit, we fix an issue where connections made through Tor's
SOCKS proxy would result in the remote address being the address of the
proxy itself
We fix this by using an internal proxyConn struct that sets the correct
address at the time of the connection.
In this commit, we clean up the tor package to better follow the
Effective Go guidelines. Most of the changes revolve around naming,
where we'd have things like `torsvc.TorDial`. This was simplified to
`tor.Dial` along with many others.
