fundingmanager: hold mutex during ctx cancellation
This commit changes cancelReservationCtx to gold the resMtx from start
to finish. Earlier it would lock at different times only when accessing
the maps, meaning that other goroutines (I'm looking at you
PeerTerminationWatcher) could come in and grab the context in between
locks, possibly leading to a race.

fundingmanager: send on resCtx.err in failFundingFlow
This commit moves the responsibility of sending a funding error on the
reservation error channel inside failFundingFlow, reducing the places we
need to keep track of sending it.

fundingmanager: send error directly in CancelPeerReservations
The error channel should never be nil, and it should always be buffered.
Because of this we can send directly on the channel.

fundingmanager: fixes range-goroutine scoping bug
This commit fixes an issue in funding manager startup,
where a goroutine reads from a range value. The method in
question could cause a channel to be announced at the
wrong time.

This may have been a cause for certain channels having
phantom HTLCs before they had even received the funding
locked message from the remote peer.

This is fixed simply by using the locally scoped
variable passed in as an argument to the goroutine.

fundingmanager: preserve remote MinHtlc during funding flow
This commit fixes a bug within the funding manager, where we would use
the wrong min_htlc_value parameter. Instead of attributing the custom
passed value for MinHtlc to the remote's constraints, we would add it to
our own constraints.

fundingmanager: preserve custom remoteCsvDelay
This commit fixes a bug that would cause the local and remote commitment
to be incompatible when using custom remote CSV delay when opening a
channel. This would happen because we wouldn't store the CSV value
before we received the FundingAccept message, and here we would use the
default value.

This commit fixes this by making the csv value part of the
reservationWithCtx struct, such that it can be recorded for use when the
FundingAccept msg comes back.

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.

fundingmanager: rebroadcast iniatior's funding txn on restart
This commit alters the behavior of the fundingmanager to
rebroadcast the funding transaction of all pending-open
channels upon restart. This is applied only to single-funder
channels for which we are the initiator, and helps ensure that
funding txns do not get stuck in the face of failures or restarts.

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.

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.

funding: on startup only re-create funding barriers if channel is pending
In this commit, we fix an existing bug within the funding manager. A
channel barrier only needs to be create if upon startup the channel is
still pending. Otherwise, we’ll re-create the funding barrier
unnecessarily. This can lead to bugs when initiating payments between a
channels’ lock in and when it’s announced to the together network. If
during this period, a user attempts a payment, then the response won’t
be archived, as the grouting will be blocked waiting on the channel
barrier to close.

To fix this, we only re-create the barrier if the channel hasn’t been
confirmed.

This eliminates one source of reported “stuck payments”.

funding: during funding error fail before sending Error to peer
In this commit, we modify the logic executed when we decide that we
need to fail a funding flow. Before this commit, if the remote party
disconnected while we were attempting to fail the funding flow with an
error. Then we'd never actually cancel the reservation. This meant that
any inputs selected for that transaction would be locked until a
restart.

We fix this issue by always cancelling the reservation first, and
ensuring that failure to cancel the reservation doesn't prevent us from
sending the error.

Partially addresses #710.

funding+server: ensure we cancel all reservations when a peer disconnects
In this commit, we fix an existing issue that could at times cause an
inconsistent view between the set of total coins, and the set of segwit
coins in the wallet of the node. This could be caused by initiating a
funding flow, but then the funding negotiation breaking down somewhere
along the lines. In this case, us or the other peer will disconnect.
When we initiate funding flows, we lock coins exclusively, to ensure
that concurrent funding flows don’t end up double spending the same
coin. Before this commit, we wouldn’t ever unlock those coins. As a
result, our view of available coins would be skewed.

The walletbalance call would show all the coins, but when adding the
—witness_only flag, some coins would be missing, or gone all together.
This is because the former call actually scans the txstore and manually
tallies the amount of available coins, while the latter looks at the
sent of available outputs, which is filtered based on which coins are
locked.

To remedy this, we now ensure that when a peer disconnects, we wipe all
existing reservations which will return any locked outputs to the set
of available outputs for funding flows.

fundingManager: handle duplicate fundingLocked
This commit adds a channel barrier on fundingManager startup for
channels where the opening process is not finished. This fixes
a bug where we after restarting the fundingManager would receive
the fundingLocked message, and crash when trying to close the
non-existing barrier.

In case we received a fundingLocked message after our own opening
process was finished, we would crash with the same error. We
therefore check if the channel barrier exists before we try to
close it.

It also adds functionality to fundingManager that makes it
ignore a fundingLocked message it receives for a channel where
this is already received. This is necessary when we in case of
a reconnection resend the fundingLocked since we cannot be sure
the remote has received it.

The fundingmanager tests are also updated to check that the
fundingLocked messages are sent and handled correcly, and also
exercise the scanarios described above.

This commit adds a conditional send on quit to all methods used by
outside sub-systems to the funding manager. This ensures, that in the
case the funding manager is exiting, the caller won’t block
indefinitely.

funding: properly display pending chan ID within logs
This commit corrects a minor formatting error when logging the pending
channel ID within the logs. Previously, the logging directives and
parameter could cause the pending chan ID to display in a double-hex
encoded format. We fix this by ensuring that we properly slice the chan
ID before printing it, and also ensure that we use the %x formatting
(which will hex encode the bytes) everywhere.

Fixes #331.

funding: properly verify and apply channel constraints during funding flow
This commit implements some missing functionality as we’ll now properly
validate and generate the various channel flow control constraints
during initial channel funding.

With this commit, we take an additional step towards full spec
compliance as we’ll now properly send over the required channel
reservation, max HTLC’s, and other parameters during the funding flow.

When processing the desired parameters by the remote party, if we think
they’re unreasonable, then we’ll send an Error message and end the
funding flow.

funding: unconditionally forward all received errors to client
Previously, our old lnwire.Error message used a special code to
indicate different types of errors. With the recent push for spec
compatibility, we removed this field and instead stuffed the error into
the first byte of the error data. This works between lnd nodes, but
with other implementations they may send different errors which use a
different error scheme.

To fix this, we’ll now unconditionally return the error to the end
caller (if one exists).

multi: ensure that BlockEpoch clients are cancelled
This commit fixes a prior goroutine leak that could result in a node
having thousands of goroutines, particularly due to many concurrent
channel fundings. We now ensure that for each BlockEpoch client
created, we ensure that the client is cancelled once the creating
grouting exits.

funding: populate ChainHash in announcement messages, update signing
This commit updates the tail end of the funding workflow to properly
include the ChainHash field when crafting ChannelAnnouncements and the
initial ChannelUpdate messages. Additionally, we now properly generate
the proper signatures to match the changes to BOLT0007.

funding: abandon usage of Code field in lnwire.Error
This commit modifies the generation and parsing of errors to abandon
usage of the Code field, and instead use the first byte of the Data
field to store the error codes that we currently use. With this change,
we ensure that our error messages properly match BOLT-0002.

849d0b93b1 fundingManager: persist state in opening process.
Persists the state of a channel opening process after funding
transaction is confirmed. This tracks the messages sent to
the peer such that the process can be continued in case of a
restart. Also introduces that the receiver side forgets about
channel if funding transaction is not confirmed in 48hrs.
