f5fb64e552 add new max channel size config option
- let users specify their MAXIMUM WUMBO with new config option which sets the maximum channel size lnd will accept
- current implementation is a simple check by the fundingManager rather than anything to do with the ChannelAcceptor
- Add test cases which verify that maximum channel limit is respected for wumbo/non-wumbo channels
- use --maxchansize 0 value to distinguish set/unset config. If user sets max value to 0 it will not do anything as 0 is currently used to indicate to the funding manager that the limit should not be enforced. This seems justifiable since --maxchansize=0 doesn't seem to make sense at first glance.
- add integration test case to ensure that config parsing and valiation is proper. I simplified the funding managers check electing to rely on config.go to correctly parse and set up either i) non wumbo default limit of 0.16 BTC OR ii) wumbo default soft limit of 10 BTC

multi: store peer flap rate on disk on best effort basis
Since we will use peer flap rate to determine how we rate limit, we
store this value on disk per peer per channel. This allows us to
restart with memory of our peers past behaviour, so we don't give badly
behaving peers have a fresh start on restart. Last flap timestamp is
stored with our flap count so that we can degrade this all time flap
count over time for peers that have not recently flapped.

multi: add interface for subscribe client so it can be mocked
The current implementation of subscribe is difficult to mock because
the queue that we send updates on in unexported, so you cannot create
a subscribe.Client object and then add your own updates. While it is
possible to run a subscribe server in tests, subscribe servers will
shutdown before dispatching their udpates to all clients, which can be
flakey (and is difficult to workaround). In this commit, we add a
subscription interface so that these testing struggles can be addressed
with a mock.

lnd: properly pass peer remote db for graph, local db for rest
In this commit, we fix a mistake in the split for the new `peer`

had the DB's swapped. In this commit, we fix this to pass the remote DB
for generic channeldb access, and the local DB for channel graph access.

multi: add labels to lnd native transactions
Follow up labelling of external transactions with labels for the
transaction types we create within lnd. Since these labels will live
a life of string matching, a version number and rigid format is added
so that string matching is less painful. We start out with channel ID,
where available, and a transaction "type". External labels, added in a
previous PR, are not updated to this new versioned label because they
are not lnd-initiated transactions. Label matching can check this case,
then check for a version number.

netann: add new HostAnnouncer to support dynamic IPs via domains
In this commit, we add a new sub-system, then `HostAnnouncer` which
allows a users without a static IP address to ensure that lnd always
announces the most up to date address based on a domain name. A new
command line flag `--external-hosts` has been added which allows a user
to specify one or most hosts that should be periodically resolved to
update any advertised IPs the node has.

Fixes #1624.

invoices: optionally hold and auto-cancel keysend payments
Adds a new configuration flag to lnd that will keep keysend payments in
the accepted state. An application can then inspect the payment
parameters and decide whether to settle or cancel.

The on-the-fly inserted keysend invoices get a configurable expiry time.
This is a safeguard in case the application that should decide on the
keysend payments isn't active.

0f50d8b2ed htlcswitch: introducing interceptable switch.
In this commit we implement a wrapper arround the switch, called
InterceptableSwitch. This kind of wrapper behaves like a proxy which
intercepts forwarded packets and allows an external interceptor to
signal if it is interested to hold this forward and resolve it
manually later or let the switch execute its default behavior.
This infrastructure allows the RPC layer to expose interceptor
registration API to the user and by that enable the implementation
of custom routing behavior.

server: ignore reconnection for unadvertised inbound peers over Tor
A peer's remote address isn't known to us if we accepted the connection
over Tor, instead we know the address the onion service used to dial to
lnd. If said peer also doesn't have any advertised addresses, then we
don't have enough information to attempt a reconnect, so we avoid doing
so. Allowing the reconnection to happen isn't necessarily an issue, but
not allowing it prevents the configured SOCKS proxy from dialing to
private addresses.

peer+server: store errors for peers with open channels
Add an error buffer to the peer struct which will store errors for
peers that we have active channels with. We do not store these errors
with peers that we do not have channels open with to prevent peers from
connecting and costlessly spamming us with error messages. When the peer
disconnects, the error buffer is offloaded to the server so that we can
track errors across connections. When peers reconnect, they are created
with their historic error buffer.

This commit enables the user to specify he is not interested in
automatically close channels with pending payments that their
corresponding htlcs have timed-out.
By requiring a configurable grace period uptime of our node
before closing such channels, we give a chance to the other node to
properly cancel the htlc and avoid unnecessary on-chain transaction.
In mobile it is very important for the user experience as otherwise
channels will be force closed more frequently.

Clock is an interface currently encapsulating Now() and TickAfter().
It can be added as an external dependency to any class. This way
tests can stub out time.Now() or time.After().

The DefaultClock class simply returns the real time.Now() and

multi: Use user provided close address for cooperative closes
This commit is adapted from @Bluetegu's original
pull request #1462.

This commit reads an optional address to pay funds out to
from a user iniitiated close channel address. If the channel
already has a shutdown script set, the request will fail if
an address is provided. Otherwise, the cooperative close will
pay out to the address provided.

multi: Set upfront shutdown from open and accept chanel messages
This commit gets upfront shutdown scripts from openchannel and
acceptchannel wire messages sent from our peer and sets upfront
shutdown scripts in our open and accept channel messages when
the remote peer supports option upfront shutdown and we have
the feature enabled.

cnct: parse onion for resolvers
With the introduction of additional payload fields for mpp, it becomes
a necessity to have their values available in the on-chain resolution
flow. The incoming contest resolver notifies the invoice registry of the
arrival of a payment and needs to supply all parameters for the registry
to validate the htlc.
