multi: specify start and end height for ListTransactionDetails
Add start and end height parameters to the rpc and cli GetTransactions
endpoints. Default to returning all transactions from genesis to tip,
including unconfirmed transactions to maintain backwards compatibility.

lnwallet/channel: enforce absolute fee floor of 250 sat/kw
This enforces the _actualized_ fee rate of the  commitment transaction,
rather than the fee floor used for estimation. The new value of 250
sat/kw corresponds to 1 sat/byte, rather than 253 which is only rounded
up during estimation to account for the fact that BOLT 3 rounds down to
the nearest satoshi and that the vbyte fee estimation is lossy.

Previously we would incorrectly fail to sign the next commitment even
though the fee was technically high enough. Restarting with this commit
should solve the issue as long as the channel hasn't already gone to
chain.

input: introduce Signature iface
This commit introduces the Signature interface which will be used by our
witness construction methods instead of passing in raw byte slices. This
will be used later to inject various kinds of mock signatures, e.g.
73-byte signatures for simulating worst-case witness weight.

lnwallet/channel: increase htlc validation strictness
This commit adds an additional santity check that rejects zero-value
HTLCs, preventing them from being added to the channel state even if the
channel config's minhtlc value is zero.

lnwallet/channel_test: assert commit sorting of commit diff htlcs
This commit adds a test to exercise that HTLC signatures are sent in the
correct order, i.e. they match the sorting of the HTLC outputs on the
commitment after applying BOLT 3's BIP69+CLTV sort.

lnwallet/channel: tie-break HTLCs by cltv when locating
This commit fixes #4118 by properly sorting the HTLC signatures sent
over the wire to match the BOLT3 BIP69+CLTV sorting of the commitment
outputs.

To do so, we expose the slice of cltv deltas for HTLCs on the unsigned
commitment after applying the commitment sorting. This will be used to
locate the proper output index, as the CLTV serves as a tie breaker
between HTLCs that otherwise have the same payment hash and amount.

Note that #3412 fixed the issue partially by ensuring the commitment was
constructed properly (and the second-level prev outpoint's txid was
correct), but failed to address that the HTLC signatures were still sent
out in the incorrect order. With this, we pass the test case introduce
in the next commit.

lnwallet/channel: populate htlc indexes from disk commit
We currently write each HTLCs OutputIndex to disk, but we don't use it
when restoring. The restoration is modified to use these directly, since
we will have lost access to the sorting of CLTVs after the initial
signing process.

lnwallet+fundingmgr: interrupt funding flow for PSBT
In case the funding manager detects that a funding flow is requested
to be executed with the help of a PsbtIntent, the normal channel
negotiation with the remote peer is interrupted, as soon as the
accept_channel message was received. With the remote peer's funding
multisig key and our local key, we can derive the funding output
script and its address. This is enough to start the PSBT funding
and signing process which the user will do externally to the daemon.

chanfunding: add PSBT assembler and intent
We add a new funding assembler and intent type that handle channel
funding through the use of a PSBT. The PsbtIntent is in itself a
simple state machine that can be stepped through the process of
assembling the required information for the funding output, verifying
a user supplied PSBT for correctness, accepting a fully signed PSBT
and then assembling the funding wire message.

method to ensure that the created channels have the proper type bit set.

lnwallet/chanfunding: add new ThawHeight() method to ShimIntent+CannedAssembler

This commit adds a similar check for the non-initiator case, checking
