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.

funding+rpc: raise min channel size to 20k satoshis
In this commit, we raise the min channel size to 20k satoshis. This
will be evaluated before we check for dusty commitments. The goal of
this is to ensure ample room for fees at current, and future fee
levels.

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.

funding: don't case to a net.TCPAddr to support tor stream isolation
In this commit, we fix an existing bug in the funding manager, that can
be triggered if the user is connecting to a node over Tor, and then
attempts to open a channel. An existing fix was added for the case that
the receiving node established the channel, but this now makes that case
symmetric.

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
[Add progress bar for chain sync] (lightninglabs/lightning-app#10) in

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.

9af7cc9b99 funding: cleanup of 6 conf and 'private' channel logic
This commits slightly rewrites the newly introduced
logic for private channels. Instead of keeping the
channel announce preference in a database within
fundingManager, it is stored as part of the
OpenChannel struct.

In addition, the ChanOpenStatus_Open update is now
sent after the channel is added to the router, instead
of waiting until the 6 blocks confirmation has passed.

This commit introduces some new interdependent functionality. As
soon as the fundingLocked message is sent, the channel is
immediately added to the ChannelRouter's internal topology.

Finally, channels are now only broadcasted to the greater
network after six confirmations on the funding transaction
has been reached.
