fundingmanager: use value the _remote_ require us to use in ChannelUpdate
This commit fixes a bug that would make us advertise the remote's
min_htlc value in our channel update.

The min_htlc value is set by a node Alice to limit its exposure to small
HTLCs, and the channel counter party should not forward HTLCs of value
smaller than this to Alice. This means that the value a node Bob should
advertise in its ChannelUpdate, is the min_htlc value the counter party
require all HTLCs to be above.

Instead of populating the ChannelUpdate with the MinHtlc value found in
the remote constraints, we now use the value from the local constraints.

funding: properly log pubkey of peer within handleInitFundingMsg
Before this commit, we would log the struct of the pubkey, rather than
the serialized compressed version.

keychain: ensure we properly set the KeyLocator for keys from DeriveNextKey
In this commit, we fix a slight bug in the existing implementation of
DeriveNextKey for btcwallet. Before this commit, we would only set the
public key, and not also the derivation path. It's important that we
also set the path information, as in the near future we'll be using the
KeyDescriptors returned from this method to create static channel back
ups. With these static backups, the key alone may be insufficient to
re-derive the private key as we may need to fallback to brute forcing in
order to re-derive the key as it's possible we add new key families in
the future.

lnwallet + funding: move funding tx publish to fundingmgr
This commit moves the responsibility for publishing the funding tx to
the network from the wallet to the funding manager. This is done to
distinguish the failure of completing the reservation within the wallet
and failure of publishing the transaction.

Earlier we could fail to broadcast the transaction, which would cause us
to fail the funding flow. This is not something we can do directly,
since the CompeteReservation call will mark the channel IsPending in the
databas.e

fundingmanager: delete active reservation after channel is in DB
This commit makes sure we delete a pending channel from the set of
activeReservations within the fundingmanager immediately after the
channel is moved to the openChannelBucket in the DB. Previously we
wouldn't do this before the funding tx was confirmed, making it possible
that failing the funding flow at a later point would try to cancel a
non-existent reservation context.

fundingmanager+lnd: remove no longer needed FindPeer and SendToPeer
callbacks

The FindPeer and SendToPeer callbacks are no longer needed within the
fundingManager due to the previous commit allowing us to send messages
to peers directly.

fundingmanager: send messages to peers directly
In this commit, we modify the existing message sending functionality
within the fundingmanager. Due to each mesage send requiring to hold the
server's lock to retrieve the peer, we might run into a case where the
lock is held for a larger than usual amount of time and would therefore
block on sending the message within the fundingmanager. We remedy this
by taking a similar approach to some recent changes within the gossiper.
We now keep track of each peer within the internal fundingmanager
messages and send messages directly to them.

fundingmanager: determine our dust limit based on active chain
In this commit, we fix an issue where we would always assume the dust
limit was Bitcoin's dust limit, rather than the active chain. This would
lead to issues when attempting to open channels on the Litecon chain.

funding+htlcswitch: enforce min fee rate of 253 sat/kw on commitments
In this commit, we add and enforce a min fee rate for commitment
transactions created, and also any updates we propose to the remote
party. It's important to note that this is only a temporary patch, as
nodes can dynamically raise their min fee rate whenever their mempool is
saturated.

Fixes #1330.

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: 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.

In this commit, we raise the min channel size to 20k satoshis. This
