lnd: reload cert data after renewal
After renewing the certificate, the new certificate wasn't actually
loaded and used, causing the old one to be used until lnd was restarted.
This fixes that by reloading it after it has been written.

lnd+cert: recreate TLS files if IPs or DNS changed
This commit makes lnd recreate its TLS certificate if the config's
tlsextradomains or tlsextraips changed. This is useful, since earlier
user would have to manually delete the files to trigger lnd to recreate
them.

To ensure users don't accidentally have their TLS certificate recreated,
we gate it behind a flag --tlsautorefresh that defaults to false.

lnd: add WalletUnlockerAuthOptions
Similar to what was done for the regular RPC server, we add auth dial
options for the wallet unlocker, as it also requires TLS now.

lnd+rpcserver: use same serverOpts for custom listeners
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.

REST: increase max msg size for REST proxy
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.

88400f5b09 lnd: close the wallet unlock grpc server
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.

multi: only allow specifying towers to TowerClient through RPC
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.

lnd: log error if any throughout initialization
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.

1fe6599fd8 lnd+chainregistry: initialize neutrino light client before wallet setup
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.

lnd+rpc: modify rpcServer to fully manaage listeners and gRPC, handle sub-servers
In this commit, we modify the existing rpcServer to fully manage the
macaroons, gRPC server, and also seek out and create all sub-servers.
With this change, the RPC server gains more responsibility, as it
becomes the "root" server in the hierarchy of gRPC sub-servers.

In addition to creating each sub-server, it will also merge the set of
macaroon permissions for each sub-server, with the permissions of the
rest of the RPC infra. As a result, each sub-server is able to
independently specify what it needs w.r.t macaroon permissions and have
that taken care of by the RPC server. In order to achieve this, we need
to unify the creation of the RPC interceptors, and also fully manage the
gRPC server ourselves.

funding+server: move initialization of funding manager into the server
In this commit, we move the initialization of the server into the
funding manager itself. We do this as it's no longer the case that _any_
RPC needs to access the funding manager. In the past, this was the
only reason that the funding manager was instantiated outside of the
server: to be able to respond to queries _before_ the server was
started.

This change also fixes a bug as atm, the funding manager will try to
register for notifications _before_ the ChainNotifier itself has fully
started.

to log before the logs have been initialized.

0720e83840 main: Stop setting GOMAXPROCS to NumCPU explicitly (#1096)
GOMAXPROCS will be set automatically after Go 1.5. The minimum version
supported at the moment is 1.9, so setting GOMAXPROCS to NumCPU is not
necessary anymore.

lnwallet+funding+lnd: add new config option for min accepted channel size
In this commit we add a new command line option (and a sane default) to
allow users to specify the *smallest* inbound channel that they'll
accept. Having a higher-ish limit lets users limit their channels, and
also avoid a series of very low value "spam" channels.

The new option is --minchansize, and expressed in satoshis. If we
receive an inbound channel request for a value smaller than this, then
we'll immediately reject it.

funding+lnd: ensure we reconnect to new channel peers
In this commit, we fix a minor bug in the prior versions of lnd. Before
this commit, if we received a new inbound connection for channel
creation, the channel was created, and then the peer disconnected, we
wouldn't automatically reconnect.

In this commit we fix this issue by overloading the WatchNewChannel
method to also accept the peer's ID so we can add it to the set of
persistent connections.

75e45b830b funding: implement reservation zombie sweeper
Before previous commits were squashed into this commit, zombie
reservations were cleaned up individually when they timed out.
However, this made the code more complex because each reservation
had its own individual timer and thus it would have required the
timer being cancelled any time the reservation was cancelled,
which would have been harder to maintain. With this commit,
zombie reservations are cleaned up by a zombie sweeper that is
set off by a ticker instead, to make the code more maintainable.

lnd: use first key in keychain.KeyFamilyNodeKey as our nodeID
In this commit, we update lnd to now access the deterministic
keychain.KeyRing struct in order to obtain our identity public key.
With this change, if the user recovers their wallet with the same seed,
then they’ll have access to the same prior node identity. This change
also makes it easy for us to support node key rotation in the future by
bumping up our requested index.

lnd: move seed generation outside wallet to allow for user supplied entropy
In this commit, we extend the initial wallet creation set up case with
the goal of giving the user the ability to restore a prior wallet from
seed, or obtain the mnemonic for a newly generated wallet.

As the WalletUnlocker has been extended to allow passing a user source
of entropy, if this is detected, then we’ll use BIP39 to covert it into
an HD wallet seed. Otherwise, we’ll generate our own entropy, then
convert that into the wallet seed.

In order to make this change, we’ll now manually create the default
wallet ourselves. In the case that the user didn’t provide their own
seed, we’ll send the seed we generated back to the user. This will allow
frontends to display the newly generated seed to the end user.

84551c616f lnwallet/lnrpc: Expose sync status to gRPC interface
This commit adds wallet_best_block_timestamp to the gRPC interface.
This is done in order to allow clients to calculate progress while
lnd syncs to the blockchain. wallet_best_block_timestamp is exposed
via the GetInfo() rpc call. Additionally, IsSynced() returns the
WalletBestBlockTimestamp as the second value in the tuple
that is returned, providing additional detail when querying about the
status of the sync. The BtcWallet interface has also been updated
accordingly.

This commit was created to support the issue to

funding+htlcswitch: dynamically update short chan id of existing link
In this commit, we fix an existing bug that would result in some
payments getting “stuck”. This would happen if one side restarted
before the channel was fully locked in. In this case, since upon
re-connection, the link will get added to the switch with a *short
channel ID of zero*. If A then tries to make a multi-hop payment
through B, B will fail to forward the payment, as it’ll mistakenly
think that the payment originated from a local-subsystem as the channel
ID is zero. A short channel ID of zero is used to map local payments
back to their caller.

With fix this by allowing the funding manager to dynamically update the
short channel ID of a link after it discovers the short channel ID.

In this commit, we fix a second instance of reported “stuck” payments
by users.

This commit reworks the macaroon authentication framework to use the
v2 macaroon format and bakery API. It also replaces the code in each
RPC method which calls the macaroon verifier with interceptors which
call the macaroon verifier instead. In addition, the operation
permissions are reworked to fit the new format of "allow" commands
(specifically, entity/operation permissions instead of method
permissions).

9a02884d0b main/lntest: factor out node config options, add options for bitcoind
This commit factors out the btcd and ltcd options into their own sections
similar to neutrino, and adds a bitcoind section as well. Now, you specify
node options similarly to:

--ltcd.rpchost=...
or
--btcd.rpcuser=...
or
--bitcoind.zmqpath=...

For Bitcoin, you specify an alternate back-end to btcd as follows:

--bitcoin.node=bitcoind
or
--bitcoin.node=neutrino

You can also specify the default option:
--bitcoin.node=btcd

For Litecoin, only `btcd` mode is valid, and corresponds to the `ltcd`
section. For example:

--litecoin.node=btcd
--ltcd.rpchost=...

The new code also attempts to read the correct options and auth info
from bitcoin.conf just as it does from btcd.conf/ltcd.conf.

lnd: make NumRequiredConfs and RequiredRemoteDelay scale with chanAmt
This commit makes the value returned fomr NumRequiredConfs
and RequiredRemoteDelay used during the funding process scale
linearly with the channel size. This is done to ensure that
in cases there are more at stake in a channel, we have more
time to react to reorgs, or unilateral closes.

If the user explicitly specified values for these two at
startup, we return those instead, without doing the scaling.

In this commit we ensure the behavior of lnd with the —noencryptwallet

waitForWalletPassword method to instead return two pass phrases: one

restarted back to the value which was used stoically in the codebase
before the latest merged PR.

824e0c2982 daemon: wait for encryption passoword at startup
This commit makes use of the UnlockerService within lnd, waiting
for the user to provide a wallet encryption passord over RPC at
startup. When the passoword is received, startup continues as
normal, either using the passowrd to create the wallet for first
time use, or unlocking an existing wallet database.

This can be skipped by setting the --noencryptwallet flag, causing
the wallet database to be encypted using the default passoword.
