If no witnesses are present on any inputs, then extended serialisation
should not be used.

The deserialization of bitcoin transactions in wire/ is rather
annoying in that we first allocate a new bitcoin_tx, then copy it's
contents onto the destination and then still carry the newly allocated
one around due to the tal-tree. This splits `pull_bitcoin_tx` into
two: one part that does the allocation and another one that proceeds
to parse.

It's just a sha256_double, but importantly when we convert it to a
string (in type_to_string, which is used in logging) we use
bitcoin_blkid_to_hex() so it's reversed as people expect.

Google lead me to a discussion about litecint, it suggested they would use
'ltc' and I don't really care.

For non-delayed HTLC success spends, we have a similar pattern ("<sig>
<preimage> <wscript>") so a we want to use the same function.
The other routines don't say "witness" in them, and should.

You will want to 'make distclean' after this.
I also removed libsecp; we use the one in in libwally anyway.

Also, we split the more sophisticated json_add helpers to avoid pulling in
everything into lightning-cli, and unify the routines to print struct
short_channel_id (it's ':', not '/' too).

To avoid everything pulling in HTLCs stuff to the opening daemon, we
split the channel and commit_tx routines into initial_channel and
initial_commit_tx (no HTLC support) and move full HTLC supporting versions
into channeld.

The signing code asserts these are NULL, and if we unmarshal from the
wire then sign them, it gets upset.

`cli` and `cli_args` were not `const` before since they are added to a
non-`const` array. Using `cast_const` we can keep them `const` without
unsafe cast.

We were using the bitcoin genesis blockhash for all networks, which is
not correct, and would result in the open being aborted when talking
to other implementations.

So far we always needed to know the public key, which was not the case
for addresses that we don't own. Moving the hashing outside of the
script construction allows us to send to arbitrary addresses. I also
added the hash computation to the pubkey primitives.
We alternated between using a sha256 and using a privkey, but there are
numerous places where we have a random 32 bytes which are neither.
This fixes many of them (plus, struct privkey is now defined in terms of
struct secret).

1) Need config.h before wire/gen_ are compiled.
2) The rule to checkout the libbase58 submodule doesn't work, so use the older
one-depends-on-the-other approach.

aka "BOLT 3: Use revocation key hash rather than revocation key",
which builds on top of lightningnetwork/lightning-rfc#105 "BOLT 2,3,5:
Make htlc outputs of the commitment tx spendable with revocation key".
This affects callers, since they now need to hand us the revocation
pubkey, but commit_tx has that already anyway.

This is a bit tricky: for our signing code, we don't want scriptsigs,
but to calculate the txid, we need them. For most transactions in lightning,
they're pure segwit so it doesn't matter, but funding transactions can
have P2SH-wrapped P2WPKH inputs.
