cnct: define separate broadcast delta for outgoing htlcs
This commits exposes the various parameters around going to chain and
accepting htlcs in a clear way.

In addition to this, it reverts those parameters to what they were
before the merge of commit d1076271456bdab1625ea6b52b93ca3e1bd9aed9.

server: stagger initial reconnects
This commit adds optional jitter to our initial reconnection to our
persistent peers. Currently we will attempt reconnections to all peers
simultaneously, which results in large amount of contention as the
number of channels a node has grows.

We resolve this by adding a randomized delay between 0 and 30 seconds
for all persistent peers. This spreads out the load and contention to
resources such as the database, read/write pools, and memory
allocations. On my node, this allows to start up with about 80% of the
memory burst compared to the all-at-once approach.

This also has a second-order effect in better distributing messages sent
at constant intervals, such as pings. This reduces the concurrent jobs
submitted to the read and write pools at any given time, resulting in
better reuse of read/write buffers and fewer bursty allocation and
garbage collection cycles.

config+peer: replace NoChanUpdates flag with NumGraphSyncPeers
In this commit, we replace the NoChanUpdates flag with a flag that
allows us to specify the number of peers we want to actively receive new
graph updates from. This will be required when integrating the new
gossiper SyncManager subsystem with the rest of lnd.

66a150297a config: default to listening for p2p on localhost when tor enabled
When Tor is enabled, this change allows manual hidden service
configuration by defaulting to listening for p2p connections on
the loopback address. It also allows overriding this manually
for situations where the Tor daemon is running on another machine,
such as when using Whonix or OnionPi-like systems.

config+rpc: create new generalized dynamic sub rpc server config framework
In this commit, we add the glue infrastructure to make the sub RPC
server system work properly. Our high level goal is the following: using
only the lnrpc package (with no visibility into the sub RPC servers),
the RPC server is able to find, create, run, and manage the entire set
of present and future sub RPC servers. In order to achieve this, we use
the reflect package and build tags heavily to permit a loosely coupled
configuration parsing system for the sub RPC servers.

We start with a new `subRpcServerConfigs` struct which is _always_
present.  This struct has its own group, and will house a series of
sub-configs, one for each sub RPC server. Each sub-config is actually
gated behind a build flag, and can be used to allow users on the command
line or in the config to specify arguments related to the sub-server. If
the config isn't present, then we don't attempt to parse it at all, if
it is, then that means the RPC server has been registered, and we should
parse the contents of its config.

The `subRpcServerConfigs` struct has two main methods:
`PopulateDependancies` and `FetchConfig`. The `PopulateDependancies` is
used to dynamically locate and set the config fields for each new
sub-server. As the config may not actually have any fields (if the build
flag is off), we use the reflect pacakge to determine if things are
compiled in or not, then if so, we dynamically set each of the config
parameters. The `PopulateDependancies` method implements the
`lnrpc.SubServerConfigDispatcher` interface. Our goal is to allow sub
servers to look up their actual config in this main config struct. We
achieve this by using reflect to look up the target field _as if it were
a key in a map_. If the field is found, then we check if it has any
actual attributes (it won't if the build flag is off), if it is, then we
return it as we expect it to be populated already.

config: parse different ZMQ hosts for block and tx notifications
Due to recent changes to the BitcoindClient interface, we now require
the backing bitcoind to use different hosts for its ZMQ raw block and
raw transaction notifications. This was needed as the notification queue
maintained by the bitcoind node would sometimes overflow with
transactions and cause block notifications to be dropped/missed.
In this commit, we expand extractBitcoindRPCParams to account for this.

In this commit, we add a new command line option to allow (ideally

bandwidth as they don't need the channel updates to passively forward
HTLCs. In the scenario that they _do_ want to update their routing
policies, the first failed HTLC due to policy inconsistency will then
allow the routing node to propagate the new update to potential nodes
trying to route through it.

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.

config+pilot: add new config params to specify min+max autopilot chan size
In this commit, we add two new configuration parameters to allow users
to specify the min and max size that the autopilot agent will create.
This is useful as now users can set the values to more or less the same
size, which will allow them to control the size of each created
channel.

Before this commit, if this wasn’t set, then the agent would try to
shove as much money into a channel up until the max chan size. This was
nice on testnet, but on main net, users will likely not want all their
funds to be in a single channel, and instead be distributed across many
channels. With things like AMP, have more channels becomes more
desirable.

This commit adds Tor support. Users can set the --TorSocks flag
to specify which port Tor's SOCKS5 proxy is listening on so that
lnd can connect to it. When this flag is set, ALL traffic gets
routed over Tor including DNS traffic. Special functions for
DNS lookups were added, and since Tor doesn't natively support
SRV requests, the proxySRV function routes connects us to
a DNS server via Tor and SRV requests can be issued directly
to the DNS server.

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.

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.

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.

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: 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.

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.
