lnwallet: ensure MayAddOutgoingHtlc doesn't add zero-value HTLCs
In this commit, in order to allow the test added in the prior commit to
pass, we'll increment the mockHTLCAmt value by 1 to ensure we never
attempt to add a zero value HTLC.

Fixes #5468

lnwallet: add test case to exercise MayAddOutgoingHtlc bug
As is, if the remote party proposes a min HTLC of 0 `mSat` to us, then
we won't ever be able to _send outgoing_ in the channel as the
`MayAddOutgoingHtlc` will attempt to add a zero-value HTLC, which isn't
allowed within the protocol.

The default channels created actually already use a min HTLC value of
zero within the tests, so this test case fails as is.

multi: refactor NewAnchorResolutions to return fixed values
This commit adds a new struct AnchorResolutions which wraps the anchor
resolutions for local/remote/pending remote commitment transactions. It
is then returned from NewAnchorResolutions. Thus the caller knows how to
retrieve a certain anchor resolution.

chainfee: change min conf target to be 1
This commit changes the minBlockTarget used by the WebAPIEstimator to be
1, inline with the bitcoind's accepted min conf target.

chainfee: replace conf target when it exceeds the maxBlockTarget
In this commit, we add a check inside EstimateFeePerKW for bitcoind so
that when the conf target exceeds the maxBlockTarget, we will use
maxBlockTarget instead.

lnwallet: prevent anchor reserve enforcement on legacy inbound channel
This commit aims to address a flaw in our anchor reserve enforcement
logic in which an inbound "legacy" channel (i.e. a channel with a
commitment type that precedes anchors) would be rejected by the
recipient if they have at least one opened channel using the anchors
commitment type and do not have enough on-chain funds to meet the
anchors reserve.

lnwallet+funding: sanitize upfront_shutdown_script
Otherwise, we would get non-standard txn's and fail to broadcast
them when cooperatively closing a channel. This wouldn't affect
funds security as no HTLCs would be active to steal. This is just
a safety measure as we should only generate standard txn's.

chanfunding: extend PSBT witness input check
Fixes #5287.

The PSBT spec is a bit vague when it comes to the WitnessUtxo field of
an input as it's not strictly required for witness inputs. Therefore
Electrum for example does not include the field.
We need to make the SegWit input check a bit more elaborate by looking
at the output script of the UTXO and also the redeem script in case it's
a nested SegWit spend.

lwallet: only count public channels towards our reserved value
Since private channels (most likely) won't be used for routing other
than as last hop, they bear a smaller risk that we must quickly force
close them in order to resolve a HTLC up/downstream.

In the case where it actually has to be force to resolve a payment (if
it is the first/last hop on a routed payment), we can assume that the
router will have UTXOs available from the reserved value from the
incoming public channel.

lnwallet: cap value reserved for anchor fee bumping
We cap the maximum value we'll reserve for anchor channel fee bumping at
10 times the per-channel amount such that nodes with a high number of
channels don't have to keep around a very large amount for the unlikely
scanario that they all close at the same time.

432b1f0588 btcwallet: lock blockcache for Neutrino GetBlock
This commit ensures that for the neutrino implementation of
lnwallet.BlockChainIO, the neutrino GetBlock method is called directly
(since it already uses the blockcache). It also ensures that the block
cache mutex for the given hash is locked before the call to GetBlock.

multi: store KeyLocator in OpenChannel, use ECDH
This commit adds a RevocationKeyLocator field to the OpenChannel
struct so that the SCB derivation doesn't have to brute-force the
sha chain root key and match the public key. ECDH derivation is now
used to derive the key instead of regular private key derivation a
la DerivePrivKey. The legacy can still be used to recover old
channels.
