d86855d1f7 feat: adds channel_state_changed notification
This notification will be raised whenever a channel state changes.
The payload includes the channel and peer identifiers and the
old and the new state.

Example payload:

```
{
    "channel_state_changed": {
        "peer_id": "03bc9337c7a28bb784d67742ebedd30a93bacdf7e4ca16436ef3798000242b2251",

        "short_channel_id" : "561820x1020x1",
        "old_state": "CHANNELD_NORMAL",
        "new_state": "AWAITING_UNILATERAL"

Changelog-Deprecated: plugin: `bcli` replacements should note that `sendrawtransaction` now has a second required Boolean argument, `allowhighfees`, which if `true`, means ignore any fee limits and just broadcast the transaction.

83298c030a wallet: switch over to withdraw in module, remove lots of unused code.
This removes the reservation cleanup at startup, too, now they're all
using 'reserved_til'.

This changes test_withdraw, since it asserted that outputs were marked
spent as soon as we broadcast a transaction: now they're reserved until
it's mined.  Similarly, test_addfunds_from_block assumed we'd see funds
as soon as we broadcast the tx.

d7ff74e8f6 json: Only start parsing once we're sure we have a message
PR #3957 improved performance considerably, however we still look over the
entire message for the message separator. If instead we just look in the
incrementally read data, we remove the quadratic behavior for large messages.

This is safe since we then loop over the messages which would drain any
message separator from the buffer before we attempt the next read.

9b8f08a8a0 lightningd: return min-capacity-sat to its intended purpose.
And document exactly what it does: insist that an HTLC can pass of
this value (module assumptions of feerate).

Note that we remove the "is_opener" test from the capacity calculation
for anchor fees: it doesn't matter which side it is, someone has to pay
for anchor fees to it deducts from capacity.

This change breaks the test, which we rewrite.
