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.

The spec 4af8e1841151f0c6e8151979d6c89d11839b2f65 uses a 32-byte 'channel-id'
field, not to be confused with the 8-byte short ID used by gossip. Rename
appropriately, and update to the new handshake protocol.

Only minor changes, but I add some more spec text to
lightningd/test/run-commit_tx.c to be sure to catch if it changes
again.
One reference isn't upstream yet, so had to be commented out.

Now we've tested it:
1. open_channel needs to write response to REQ_FD not STATUS_FD.
2. recv_channel needs to send our next_per_commit, not echo theirs!
3. print the problematic signature if it's wrong, not our own.
Cleanups:
1. Return the message from open_channel/recv_channel for simplicity.
2. Trace signing information.
3. More tracing messages.

Or for blackbox tests --gdb1=<subdaemon> / --gdb2=<subdaemon>.
This makes the subdaemon wait as soon as it's execed, so we can attach
the debugger.

The requirements for accepting the remote config are more complex than
a simple min/max value, as various parameters are related. It turns
out that with a few assumptions, we can boil this down to:
1. The valid feerate range.
2. The minimum effective HTLC throughput we want
3. The a maximum delay we'll accept for us to redeem.
