We also update since the merged version sets feature bit 9 (as it's
supposed to now that we tied that to payment_secret).

This fixes block parsing on testnet; specifically, non-standard tx versions.
We hit a type bug in libwally (wallt_get_secp_context()) which I had to
work around for the moment, and the updated libsecp adds an optional hash
function arg to the ECDH function.
Fixes: #2563

I tried to just do gossipd, but it was uncontainable, so this ended up being
a complete sweep.
We didn't get much space saving in gossipd, even though we should save
24 bytes per node.

This is mainly just copying over the copy-editing from the

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.

tal_count() is used where there's a type, even if it's char or u8, and
tal_bytelen() is going to replace tal_len() for clarity: it's only needed
where a pointer is void.
We shim tal_bytelen() for now.

structeq() is too dangerous: if a structure has padding, it can fail
silently.
The new ccan/structeq instead provides a macro to define foo_eq(),
which does the right thing in case of padding (which none of our
structures currently have anyway).
Upgrade ccan, and use it everywhere. Except run-peer-wire.c, which
is only testing code and can use raw memcmp(): valgrind will tell us
if padding exists.
Interestingly, we still declared short_channel_id_eq, even though
we didn't define it any more!

These were so far only used for bolt11 construction, but we'll need them for the
DNS seed as well, so here we just pull them out into their own unit and prefix
them.

We can have more than one; eg we might offer both bech32 and a p2sh
address, and in future we might offer v1 segwit, etc.

I didn't convert all tests: they can still use a standalone context.
It's just marginally more efficient to share the libwally one for all
our daemons which link against it anyway.

We don't use it yet, but now we'll decode correctly.
