The original idea is to "tal" channel on the "ctx"(In fact, we'd like to set ctx as "ld").
But we already tal channel on "ld" in new_channel(), so "ctx" is unused.
These are always handed to subdaemons as a set, so group them. This makes

We were deciding whether an address is a testnet address or not in the parser,

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.

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".

1. amount operations should force you to check validity, rather than
needing a separate call, so make amount_msat_to_u32 return bool,

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

This field was used by `pay` to hold the bolt11 description if the bolt11
string used `h` to hash the description (which nobody ever did). If the

It's really useful to have a label for payments (eg. '1 Cuban'), but adding

jsonrpc: added error code FUNDING_BROADCAST_FAIL

This makes the user more aware of broadcast failure, so it hopefully doesn't

Notice that the serializer and deserializer is skipped if we don't
have a plugin that registered for this hook.

plugin_request_new did nothing special aside from registering the
request ID with the dispatch code. This duty has now been moved to
plugin_request_send instead, which is also exposed so we can use that
code in plugin_hook.

This is the first use of the `hooks` autodata field, and it required a
dummy element in order for the section not to be dropped, it'll be
removed once we have actual hooks.
There is very little that is plugin specific in the jsonrpc_request so
this just extracts the common parts so we can reuse them outside of
the plugin compilation unit as well.
None of the existing callbacks was making use of it and we will be
exposing the method callback interface to outside compilation unit
where the struct definition is not visible. So just remove it.

I might have gone a bit overboard with the type-checking, but
typesafe_cb_cast is quite nice to use, so why not. The macro to
register a new hook encapsulates the entire flow from param
serialization, to dispatch, parsing and callback dispatch in one
bundle. I was tempted to have the callback outside of the
registration, but it's unlikely that we'll have two calls to the same
hook with different callbacks.

Currently only used by gossipd for channel elimination.
Also print them in canonical form (/[01]), so tests need to be
changed.
