f34d0b1cf5 plugins/txprepare: create simple variant for "withdraw".
This is a little lazy, but simpler than extracting the common parts
or making withdraw a plugin which calls txprepare (which should be
deprecated soon in favor of fundpsbt etc).

3b8c0a7397 sendpsbt: just reserve (maybe bump) inputs on send, don't mark spent.
Marking spent means if the transaction doesn't confirm for some
reason, the user will need to force a rescan to find the funds.  Now
we have timed reservations, reserving for (an additional) 12 hours
should be sufficient.

We also take this opportunity (now we have our own callback path)
to record the tx in the wallet only on success.

8d5ff210bf txprepare: a plugin to replace txprepare (not yet active).
This uses `fundpsbt` and similar to simulate the txprepare command.
It has one difference (when complete), in that it those reservations
are now timed and don't get reset on restart.

It also doesn't have the restriction that `all` can only be used with
no other output, as I didn't realize that when I implemented it!

Note that change is now inserted in a random position, not sorted
into BIP69 order.

d7ff74e8f6 json: Only start parsing once we're sure we have a message
PR #3957 improved performance considerably, however we still look over the
entire message for the message separator. If instead we just look in the
incrementally read data, we remove the quadratic behavior for large messages.

This is safe since we then loop over the messages which would drain any
message separator from the buffer before we attempt the next read.

31c67f1392 bcli: Avoid tal_fmt when handling a raw hex block
We were using `tal_fmt` to truncate off the last byte of the
response (newline), which required an allocation, a call to `vsnprintf` and a
copy of the block contents. This being >2MB in size on mainnet was rather
expensive.

We now just signal the end of the string by overwriting the trailing newline,
and stealing directly onto the result.

76813d6f90 tools/generate-wire.py: fix varsize assignment.
Code like this is suspicious:

	subtype_varsize_struct->field_0 = *fromwire_test_features(subtype_varsize_struct, cursor, plen);

In fact, it is a memory leak since we copy and don't free the fromwire
result.  Really, field_0 should be a pointer.

We don't hit this case (yet!) in spec-generated code, but I did for
bolt13.

	You gave bad parameters: channel capacity with funding 20000sat, reserves 546sat/546sat, max_htlc_value_in_flight_msat is 18446744073709551615msat, channel capacity is 9818sat, which is below 10000000msat

this value (module assumptions of feerate).

for anchor fees to it deducts from capacity.

This change breaks the test, which we rewrite.
