config: add stricter config parsing to avoid dangerous RPC auth combos
In this commit, we add an additional constraint to the RPC
configuration parsing. Before this commit, it was possible to start lnd
with either RPC server listening on an external interface *without*
authentication disabled. After this commit, if a user tries to start
the RPC server listening on an external interface without any sort of
RPC authentication, then the daemon will fail to start up.

4559438c4b config.go: check for RPCUser AND RPCPass (AND ZMQPath for bitcoind)
This commit causes the configuration parser to accept the values of
RPCUser, RPCPass, and (for the bitcoind back-end) ZMQPath configured
in lnd.conf or on the command line ONLY when all are specified. It
causes the configuration parser to look in btcd.conf or bitcoin.conf
ONLY when none are specified, and causes an error to be returned when
only some are specified, as users have done so erroneously and the
lack of clear feedback has caused difficulties.

test: add comprehensive integration tests for on-chain HTLC handling
In this commit, we add 6 new integration tests to test the various
actions that may need to be performed when either side goes on-chain to
fully resolve HTLC’s. Many of the tests are mirrors of each other as
they test sweeping/resolving HTLC’s from both commitment transactions.

86133e559b config: add peer, rpc, and rest listener options
This commit removes the `peerport` and `rpcport` config options and
adds `listen`, `rpclisten`, and `restlisten` options to allow setting
one or multiple interfaces to listen on for incoming connections.

It also adds a `nolisten` option to allow disabling the listener for
incoming peer connections.

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.

config: make DefaultNumChanConfs part of chainConfig
This commit moves the definition of DefaultNumChanConfs into
the chainConfig (such that it is set as e.g.
"--bitcoin.defaultchanconfs"), making it possible to set
individually for different chains.

It also adds the flag DefaultRemoteDelay to the chainConfig,
which can be used to set the CSV delay we will require the remote
to wait before retrieving its own funds in case of an
uncooperative close of the channel.

Both these are set 0 by default (if not specified by the user),
which in that case we will dynamically set the values, scaling
them according to the channel size.

config+test: increase default num confs for funding flows to 3
In this commit, we increase the default number of confirmations we
require for funding flows from 1 to 3. The value of 1 was rather
unstable on testnet due to the frequent multi-block re-orgs.
Additionally, a value of 3 ensures our funding transaction is
sufficiently buried before we deem is usable.

multi: retain original copyright on files copied/modified from btcsuite
Early in the lifetime of the project here were a few files we either
copied entirely, or used as the basis for code within lnd. Before this
PR, this was not recognized by retaining the original copyright. With
this commit, we remedy that by explicitly noting the copyright in the
relevant files.

Fixes #423.

config: use a single global macaroon database, scope macaroons in datadir
This commit modifies the way that we create the macaroon database, and
also create the initial macaroons themselves. Rather than creating a
new macaroon DB for each chain, we instead create a single instance for
all chains. Additionally, if the datadir has been modified, and the
macaroon paths haven’t been modified, the macaroons are now scoped to
those paths.

352461d551 config: add regtest support to lnd
Support for regtest allows us to create integration tests to verify
interoperability with other implementations. This seems to work, and
allows to connect to `btcd` and indirectly to `bitcoind` so we can run
lnd on the same network as eclair and c-lightning.

8fa2b95c12 lnd: remove seelog logger
The btclog package has been changed to defining its own logging
interface (rather than seelog's) and provides a default implementation
for callers to use.

There are two primary advantages to the new logger implementation.

First, all log messages are created before the call returns.  Compared
to seelog, this prevents data races when mutable variables are logged.

Second, the new logger does not implement any kind of artifical rate
limiting (what seelog refers to as "adaptive logging").  Log messages
are outputted as soon as possible and the application will appear to
perform much better when watching standard output.

Because log rotation is not a feature of the btclog logging
implementation, it is handled by the main package by importing a file
rotation package that provides an io.Reader interface for creating
output to a rotating file output.  The rotator has been configured
with the same defaults that btcd previously used in the seelog config
(10MB file limits with maximum of 3 rolls) but now compresses newly
created roll files.  Due to the high compressibility of log text, the
compressed files typically reduce to around 15-30% of the original
10MB file.

config: don't log to stderr if lnd.conf isn't found
This commit fixes a bit of a wart in the configuration file handling
wherein if the config file isn’t found, an error was printed to stderr.
At times, this would cause the testing framework to erroneously mark as
test as failed. Instead, we now keep a particular config file error,
and check that, printing to a warning log level.

This commit fixes a bug introduced by the new multi-chain features of

Previously if two local nodes were set to, the _same_ chain, then
they’d both share the same chain data directory which would prevent one
of the nodes from being able to start up properly.

config: modify configuration to be aware of multi-chain paramters
This commit modifies the existing configuration to create instances
that are capable of housing configuration options for a particular
chain such as the rpcuser or rpcpass to distinct structures within
greater configuration. With this new change, it will now be possible
for lnd to be resident on either the litecoin testnets, with simple a
toggle in the main configuration.

The new configuration file will look like the following:
   [Bitcoin]
   bitcoin.active
   bitcoin.testnet=1
   bitcoin.rpcuser=kek
   bitcoin.rpcuass=kek

Similarly, one would mirror a similar set up in order to be active on
the latest litecoin testnet.

config: add automatic btcd RPC configuration for testnet
A common pitfall with new users setting up lnd on test net has been
observed to be the initial RPC credential set up between btcd and lnd.
As of a recent version of btcd now performs automatic RPC credential
set up by generating a random rpcuser and rpcpass on start up.

We now take advantage of this by reading the RPC credentials (if
possible and running in simmer mode). As a result, it is now possible
to simply run: `lnd—testnet` assuming a fresh installation of bcd (with
a set btcd.conf).

Fixes #68.

config+test: use default port for RPC server if one isn't specified
This commit alters the configuration parsing a bit along with the
documentation to expect the RPCHost configuration paramter to also have
the target port specified. If the port isn’t included, then the default
btcd RPC port for that chain is used.

Additionally, within the integration testing framework, when creating
the lnd nodes, we now use the configuration from the btcd harness to
set the proper RPC host.

lnd: switch to using the connmgr for listening and persistent conns
This commit revamps the way in bound and outbound connections are
handled within lnd. Instead of manually managing listening goroutines
and also outbound connections, all the duty is now assigned to the
connmgr, a new btcsuite package.

The connmgr now handles accepting inbound (brontide) connections and
communicates with the server to hand off new connections via a
callback. Additionally, any outbound connection attempt is now made
persistent by default, with the assumption that (for right now),
connections are only to be made to peers we wish to make connections
to. Finally, on start-up we now attempt to connection to all/any of our
direct channel counter parties in order to promote the availability of
our channels to the daemon itself and any RPC users.

By default, this flag is false, it it only intended to be used to
exercise local changes to 1-hop behavior manually.
