Rusty Russell ec72d89975 bolt11: reorder invoice production to match test vectors.
After this, we can exactly reproduce the vectors (in DEVELOPER mode).

1. Move payment_metadata position to match test vector.
2. Create flag to suppress `c` field production.
3. Some vectors put secret before payment_hash, hack that in.

Rusty Russell 2526e804f7 doc: big BOLT update to incorporate warnings language.
We do this (send warnings) in almost all cases anyway, so mainly this
is a textual update, but there are some changes:

1. Send ERROR not WARNING if they send a malformed commitment secret.
2. Send WARNING not ERROR if they get the shutdown_scriptpubkey wrong (vs upfront)
3. Send WARNING not ERROR if they send a bad shutdown_scriptpubkey (e.g. p2pkh in future)
4. Rename some vars 'err' to 'warn' to make it clear we send a warning.

This means test_option_upfront_shutdown_script can be made reliable, too,
and it now warns and doesn't automatically close channel.

Rusty Russell 9f06a59e3c shutdown: don't allow shutdown to p2pkh or p2sh addresses for anchor outputs.
This doesn't have an effect now (except in experimental mode), but it
will when we support anchors.  So we deprecate the use of those in the
close command too.

For experimental mode we have to avoid using p2pkh; adapt that test.

Rusty Russell 7491af5495 doc: update BOLT references part1, including bolt11 test vectors with payment_secret.
The signatures on the new examples are sometimes different from what we produce though?
They're valid, however.

And one example has an unneeded feature 5-bit; it's not *wrong*, but
it's not optimal.

Rusty Russell 83ee68ab06 common/tlvstream: put TLV checking back in the generic function.
Callers were supposed to call "tlv_fields_valid" after fromwire_tlv,
but few did.  Make this the default, and call the underlying function
directly where we want to be more flexible (one place).

This loses the ability to allow misordered fields, or to pass through
*any* even fields.  We restore that for special cases in the next
patch.

Rusty Russell 65be18d355 memleak: handle libwally allocations better.
Things allocated by libwally all get the tal_name "wally_tal",
which cost me a few hours trying to find a leak.

In the case where we're making one of the allocations the parent
of the others (e.g. a wally_psbt), we can do better: supply a name
for the tal_wally_end().

So I add a new tal_wally_end_onto() which does the standard
tal_steal() trick, and also changes the (typechecked!) name.

We often hand an exclude pointer (usually the current command) to

previously-undetected leaks.

Rusty Russell ea71e9fe5b memleak: fix handling of notleak pointers.
We were ignoring the *parent* of the notleak pointers, not the notleak
pointer itself!

Rusty Russell 3218e5332f common/param: fix leak with opt_param_def.
We allocate the default, then callback allocates over the top.  Mark
params with a default, so we can free that when it's called.

(We can't do this generally, since not all param args are actually
pointers to pointers, though opt_param_def has to be).

Rusty Russell 4b7d2dc5b8 common/bolt11: make decoded routes hang off routes arr, not b11.
This causes weirdness in pay, which tal_steal's b11->routes and expects
to get it all.

William Casarin af16b9b9f4 bolt11: mark when we decode min_final_cltv_expiry
It looks like decode_c doesn't set have_c unlike the other decode_
methods. At the start of the function, decode_c checks have_c to see if
it's set, but it is never set. It seems like this could allow for
duplicate c tags, which is probably not intended.
