lnwallet+funding: pass the pending channel ID into the reservation context
In this commit, we start to thread the pending channel ID from wire
protocol all the way down into the reservation context. This change will
allow negotiation to take place _outside_ the protocol that may result
in a particular chanfunding.Assembler being dispatched.

lnwallet: delegate all channel funding logic to the new chanfunding package
In this commit, we begin to integrate the new channel funding package
into the existing codebase. With this set of changes, we'll no longer
construct and sign the funding transaction within this package, instead
delegating it to the new chanfunding package. We use the new
chanfunding.WalletAssembler to carry out all channel funding, providing
it with an implementation of all its interfaces backed by the wallet.

chainfee: create new chainfee package extracting fees from lnwallet
In this commit, we create a new chainfee package, that houses all fee
related functionality used within the codebase. The creation of this new
package furthers our long-term goal of extracting functionality from the
bloated `lnwallet` package into new distinct packages. Additionally,
this new packages resolves a class of import cycle that could arise if a
new package that was imported by something in `lnwallet` wanted to use
the existing fee related functions in the prior `lnwallet` package.

multi: convert the existing channeldb.ChannelType uint8 into a bit field
In this commit, we convert the existing `channeldb.ChannelType` type
into a _bit field_. This doesn't require us to change the current
serialization or interpretation or the type as it is, since all the
current defined values us a distinct bit. This PR lays the ground work
for any future changes that may introduce new channel types (like anchor
outputs), and also any changes that may modify the existing invariants
around channels (if we're the initiator, we always have the funding
transaction).

multi: update funding workflow to be aware of new tweakless commits
In this commit, we update the funding workflow to be aware of the new
channel type that doesn't tweak the remote party's output within the
non-delay script on their commitment transaction. To do this, we now
allow the caller of `InnitChannelReservation` to signal if they want the
old or new (tweakless) commitment style.

The funding tests are also updated to test both funding variants, as
we'll still need to understand the legacy format for older nodes.

multi: move Input interface and related code
This commit is a step to split the lnwallet package. It puts the Input
interface and implementations in a separate package along with all their
dependencies from lnwallet.

Revert "funding+lnwallet: ensure max_htlc_value_in_flight smaller than capacity"
This reverts commit 4aa52d267f000f84caf912c62fc14a5b8e7cacb5.

It turns out that the other implementations set values for this field
which aren't based on the actual capacity of the channel. As a result,
we'll no reject most of their channel offerings, since they may offer a
value of a max `uint64` or something else hard coded that's above the
size of the channel. As a result, we're reverting this check for now to
maintain proper compatibility.

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

lnwallet: in NewChannelReservation ensure commit fees are payable
In this commit, we fix a bug introduced by the recent change of
lnwire.MilliSatoshi to be an unsigned integer. After this change an
integer underflow was left undetected, as a result we’ll now
momentarily cast to a signed integer in order to ensure that both sides
can pay the proper fee.

lnwallet: add new method to register our preferred minHTLC value
Before this commit, during a reservation, we wouldn’t ever specify our

doing this now serves to ensure that once those features are merged,
we’ll actually be setting a valid value for minHTLC.

lnwallet: make 1% reservation computation clearer
Adding 99 here didn’t really do anything but obfuscate when we were
trying to compute. We’re just using internet division to calculate 1%
of the channel capacity amount. This is the amount that the remote
party must remain above at all times.

lnwallet: add new methods to ChannelReservation for dealing w/ chan constraints
This commit adds to methods to the ChannelReservation struct: one for
generating the channel constraints we require for the remote party, and
one for validating their desired constraints, and committing them to
our ChannelConfig.

With these two new methods, we can now begin to properly store and
adhere to the current set of channel flow control constraints.

lnwallet: update Channel[Reservation+Contribution] for new funding flow
This commit updates the channel reservation workflow in order to
properly implement the new funding workflow defined in BOLT-0002.

The workflow itself hasn’t changed significantly, but the contents of
the contributions of both sides have. The bulk of the fields within the
contribution of both sides has been boiled down into a pointer to the
ChannelConfig which houses all the data required to handle all states
of the channel, and commitment state machine.

For the two portions which are dictated by the other party, we now add
builder-like modifiers to allow specifying the constraints after the
initial portion of the workflow.

lnwallet: simplify remote balance computation for single funder
The remote balance in the case of a single funder workflow is simply
what ever the pushSat amount is. The capacity - fundingAmt in this
scenario would always be zero, so we simply just set it directly to
pushSat.

4ac7cc719f lnwallet: replace hard-coded fees and adjust tests accordingly
This commit replaces the hard-coded 5000 satoshi fees with calls to the
FeeEstimator interface. This should provide a way to cleanly plug in
additional fee calculation algorithms in the future. This change
affected quite a few tests. When possible, the tests were changed to
assert amounts sent rather than balances so that fees wouldn't need to
be taken into account. There were several tests for which this wasn't
possible, so calls to the static fee calculator were made.
