this method will be needed in swaps as we can't use sendTransfer for unlocking HTLCs (i.e. needed for swaps v1 and v2)
which forces us to return Public instead of &Public from this function, and a whole wave of ripple effects all over
no watchers, just plain swaps v1 methods
the caller needs to provide a map of utxo transactions for the p2pkh inputs, otherwise signing will fail
soley contained in geenrate_and_send_tx
…s in utxo_common so kdf won't panic cuz we don't have walletconnect we better remove these panics tho note that not all these methods are needed for swap v1. but i did them nontheless
requires manual testing with walletconnect capable wallets by the test step by step
idk why we sent the watcher message one time then moved to the next step and created a handle to keep sending it periodically. this commit makes it so we don't do the initial send but only create the handler to keep sending it periodically as before (this part didin't change, but the log message was put in the appropriate place)
this is to be handled in a different PR since it seems it might be complext. we need to sign the watcher msg with the htlc privkey which means we will ask walletconnect for one more signature. this might get entangled with p2p crate code
via reverting back to use derive_htlc_key_pair using the unique swap data
…etconnect signing yet to be tested
This reverts commit 5bf8727.

we don't need the custom error message given we already have the error trace using MmError
…ctions for both: p2pkh and p2sh

This PR adds support for swaps v2 (TPU) via WalletConnect for UTxO.
The only difference in transaction signing between v1 and v2 swaps are just the co-operative signing step in:
funding spend (aka taker payment)taker payment spend (aka finalizing tx)In these two, each side performs pretty much the same P2SH signing call as before but only stores (and sends) the bare signature returned from WalletConnect. This is analogous to calling
calc_and_sign_sighashusing aKeyPair.And then the same process as before goes on: signatures are later combined to create the complete
script_sig, etc...A manual test is added for this feat:
test_walletconnect_swap_v2, and this: #2566 (comment) is how to run it.
