Adds a global Authenticate method that can be used to get the
atuhentication options needed to call the grpc server.
Currently meant only for used with the mobile bindings, so we use the
admin macaroon.
Earlier we used emtpy grpc server options if custom listeners were set.
This was done to disable TLS. Now, we reuse the same server options as
for the regular listeners, in a move towards enabling TLS also here.
ListenerCfg allows passing custom listeners to the main method, to be
used for the wallet unlocker and rpc server. If these are set these will
be used instead of the regular RPC listeners.
Some time ago, we modified `lncli` to accept larger responses from the
server, up to 50MB. However, we failed to update the REST proxy, which
is in a sense, a client to the regular RPC server. As a result, users
can't currently hit the `/v1/graph` endpoint, as it'll fail with an
error.
In this PR, we update the proxy's dial options to allow it to receive
larger responses from the actual gRPC server. This is only a temporary
measure however, as we'll eventually want to expose some sort of
pagination for the end client.
The server was kept alive long after it stopped being used. This caused
problems for services using long-lived GRPC connections which might be
created before wallet unlocked. They got stuck connected to the wallet
unlock service needing a restart.
With the introduction of the WatchtowerClient RPC subserver, the lnd
configuration flag to specify private watchtowers for the client is no
longer needed and can lead to confusion upon users. Therefore, we remove
the flag completely, and only rely on the watchtower client being active
through a new --wtclient.active flag.
In this commit, we establish a new pattern to always log errors before
returning them to the higher level caller, which then prints the error
to stdout/stderr. Errors returned are usually lowercase, but we decide
not to apply this rule here as these errors should not be chained
forward.
A cleanup closure is not included when an error is returned, causing the
defer to execute and triggering the following panic:
panic: runtime error: invalid memory address or nil pointer dereference
[signal SIGSEGV: segmentation violation code=0x1 addr=0x0 pc=0x105da38]

This commit restructures the creation of various tls related object. It
also fixes a bug where wildcard IP addresses where only instantiated for
the main RPC server and not the WalletUnlocker service.
In this commit, we modify the server to serve the role as the agent
which will carry out the SCB restoration protocol if the Init/Unlock
methods include a set of channels to be recovered.
In this commit, we slightly refactor the startup of lnd when running
with a Neutrino light client backend. We'll now begin syncing our
backend as soon as lnd starts and passes all configuration checks. Since
this is all done before lnd's wallet setup, the light client will be
syncing in the background while the user notes/inputs their wallet seed.
This is done in order to provide a better UX from the point of the user,
such that most of the chain will already be synced by the time they get
to deposit funds into the wallet.
