Rusty Russell 443082ba98 common: add peer_failed_warn_nodisconnect routine for non-disconnecting warnings
We generalize the current df-only "aborted" flag (and invert it) to a
"disconnected" flag in the peer status message.

We convert it back to the aborted flag for now inside subd.c, but that's
next.

Also, we don't need to keep the log_book in struct plugin, since it has
access to ld's log_book.

Rusty Russell edbaa944da lightningd: switch parsing to common/configvar
Now we wire in the code which gathers configvars and parses from there;
lightningd keeps the array of configuration variables for future use.

Note that lightning-cli also needs to read the config, but it has its
own options (including short ones!) and doesn't want to use this
configvar mechanism, so we have a different API for that now.

niftynei 195a2cf44b dual-open: use tx-abort instead of warning/errors
When a channel open fails, we use tx-abort instead of warning/error.

This means that the peer won't disconnect! And instead when a new
message arrives, we'll need to rebuild the dualopend subd (if missing).

Makes opens a bit easer to retry (no reconnect needed), as well as keeps
the connection alive for other channels we may have with that peer.
