niftynei dc868630a8 tx-psbt: pass in the witness script (if known) when adding an input
Update the `bitcoin_tx_add_input` interface to accept a witness script
and or scriptPubkey.

We save the amount + witness script + witness program (if known) to
the PSBT object for a transaction when creating an input.

niftynei fbe50e087a setup: create a common setup which will handle the wally-context
Since we now over-write the wally malloc/free functions, we need to do
so for tests as well. Here we pull up all of the common setup/teardown
logic into a separate place, and update the tests that use libwally to
use the new common_setup core

lisa neigut 0e20e3c5e7 df: rename 'funder' to 'opener'
Previously we've used the term 'funder' to refer to the peer
paying the fees for a transaction; v2 of openchannel will make
this no longer true. Instead we rename this to 'opener', or the
peer sending the 'open_channel' message, since this will be universally
true in a dual-funding world.

Rusty Russell b29d1ed3ff channeld: support HTLCs with blinding (EXPERIMENTAL_FEATURES)
Note that it's channeld which calculates the shared secret, too.  This
minimizes the work that lightningd has to do, at cost of passing this
through.

We also don't yet save the blinding field(s) to the database.

Rusty Russell ed839bfda0 channeld: get the onionreply back from lightningd for failed htlcs.
Instead of making it ourselves, lightningd does it.  Now we only have
two cases of failed htlcs: completely malformed (BADONION), and with
an already-wrapped onion reply to send.

This makes channeld's job much simpler.

Rusty Russell aca2e4f722 common/memleak: add dynamic hooks for assisting memleak.
Rather than reaching into data structures, let them register their own
callbacks.  This avoids us having to expose "memleak_remove_xxx"
functions, and call them manually.

Under the hood, this is done by having a specially-named tal child of
the thing we want to assist, containing the callback.

4. Rename channel_tell_funding_locked to channel_tell_depth.
5. Call channel_tell_depth even if depth < minimum, and still call
lockin_complete in channel_tell_depth, iff depth > minimum_depth.
6. channeld ignore the channel_funding_depth unless its >

Rusty Russell 7fad7bccba common/amount: new types struct amount_msat and struct amount_sat.
They're generally used pass-by-copy (unusual for C structs, but
convenient they're basically u64) and all possibly problematic
operations return WARN_UNUSED_RESULT bool to make you handle the
over/underflow cases.

The new #include in json.h means we bolt11.c sees the amount.h definition
of MSAT_PER_BTC, so delete its local version.

This is prep work for when we sign htlc txs with
SIGHASH_SINGLE|SIGHASH_ANYONECANPAY.

We still deal with raw signatures for the htlc txs at the moment, since
we send them like that across the wire, and changing that was simply too
painful (for the moment?).

We probably also want to call secp_randomise/wally_secp_randomize here
too, and since these calls all call setup_tmpctx, it probably makes
sense to have a helper function to do all that. Until thats done, I
modified the tests so grepping will show the places where the sequence
of calls is repeated.
