* remove libbase58, use base58 from libwally
This removes libbase58 and uses libwally instead.
It allocates and then frees some memory, we may want to
add a function in wally that doesn't or override
wally_operations to use tal.

Without this, the connect command hangs in one of my branches. This logic
is from the old days when gossipd handled connections, and we wanted
to make sure it didn't hang up on this client due to the error.

I misunderstood the API, this ended up nesting a result inside the JSON-RPC
result.
No concerns about backwards compatibility since this is so new.

This seems like overkill, at least for now. Handling the JSON
inline is clearer, for the existing examples at least.
We also remove the dummy hook, rather than fix it.

The old value of 1000 sat was too small to cover the dust reserves.
This lead to the situation when trying to open a channel with minimal
amount, the channels got refused because they were not able cover the
commitment fees.
For this reason the minimal capacity should be increased to i.e. 10k
satoshi, as the technical minimum that also accounts for fees and
reserves is somewhere around 6k sat.
Refactored the weighted-reservoir-sampling algo to make it more straightforward.
It now uses the excess as fraction of capacity as weight. This favors channels that
are more _relatively_ unbalanced to be used for incoming payment.
Now passes test_invoice_routeboost_private() when using max fundamount=16777215.
make it a bit easier to track mutual channel closures by
adding broadcast txid to the listpeers billboard.
since lightningd manages the 'identity' of the closing tx we need
to send it back to closingd so it can update the billboard
appropriately.
This also allows plugins to do "hold invoices" a-la LND, useful for
just-in-time inventory handling.
We're careful to handle the invoice getting paid behind our backs, and
the incoming HTLC going away.
Once @cdecker's sphinx rework is in, we can also hand the raw payload
to the invoice_payment_hook, for special effects.

We're going to make it async, so start by moving the core code into
invoice.c and having that directly call fail/success functions for the
htlc.
We add an extra check in fulfill_htlc() that the HTLC state is correct:
that can't happen now, but may once we're async.

Node ids are pubkeys, but we only use them as pubkeys for routing and checking
gossip messages. So we're packing and unpacking them constantly, and wasting
some space and time.
This introduces a new type, explicitly the SEC1 compressed encoding
(33 bytes). We ensure its validity when we load from the db, or get it
from JSON. We still use 'struct pubkey' for peer messages, which checks
validity.

I started by trying to change the current infrastructure, but this is

1. Rename channel_funding_locked to channel_funding_depth in
channeld/channel_wire.csv.
2. Add minimum_depth in struct channel in common/initial_channel.h and
change corresponding init function: new_initial_channel().
3. Add confirmation_needed in struct peer in channeld/channeld.c.
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 >
minimum_depth(except to update billboard, and set
peer->confirmation_needed = minimum_depth - depth).
- This will make a channel loop when 'id' argument was "all".
- The response will now contain an array of objects (peer_id, scid, ...)
- It will skip channels in invalid states.
- Moves iffy channel/peer param stuff to param_channel_or_all
We set the version BIP32_VER_TEST_PRIVATE for testnet/regtest
BIP32 privkey generation with libwally-core, and set
BIP32_VER_MAIN_PRIVATE for mainnet.
For litecoin, we also set it like bitcoin else.
1. amount operations should force you to check validity, rather than
needing a separate call, so make amount_msat_to_u32 return bool,
and WARN_UNUSED_RESULT it.
2. Create a special parsing function for this; not only does this mean
we now only need that one amount call, but also 'check' will correctly
fail with invalid amounts (it only does the parsing step).
3. If we create a primitive which we immediately take(), we allocate it
off NULL to make it clear we expect its lifetime to end here.
