Rusty Russell 3c97f3954e daemon_conn: make it a tal object, typesafe callbacks.
It means an extra allocation at startup, but it means we can hide the definition,
and use standard patterns (new_daemon_conn and typesafe callbacks).

lisa neigut 0ae1d03513 BOLT7: broadcast `htlc_maximum_msat` in `channel_update s
Have c-lightning nodes send out the largest value for
`htlc_maximum_msat` that makes sense, ie the lesser of
the peer's max_inflight_htlc value or the total channel
capacity minus the total channel reserve.

lisa neigut b1ceaf9910 gossipd: Update BOLT-split flags in channel_update
BOLT 7's been updated to split the flags field in `channel_update`
into two: `channel_flags` and `message_flags`. This changeset does the
minimal necessary to get to building with the new flags.

Rusty Russell 5b2e829b4f hsmd: remove master pointer.
We used to use it to complain about bad requests, but we use the status conn
now, so it's unused except for tests and asserts.

Rusty Russell 019bc4fcd7 hsmd: reorder functions (MOVEONLY).
We don't need to pre-declare any more, but I left it in the previous
patch for review simplicity.

Rusty Russell b0769d9c0c hsmd: don't use daemon_conn for clients.
It offers them a DoS vector, if they don't read the replies.  We really want
to use raw ccan/io so we can avoid buffering for this.

It makes the handing of fds for new clients a bit more complex
(callback based), but it's not too bad.

Rusty Russell e012e94ab2 hsmd: rename hsm_client_wire_csv to hsm_wire.csv
That matches the other CSV names (HSM was the first, so it was written
before the pattern emerged).

Rusty Russell 6b6b7eac61 hsmd: use status_conn to send bad_request messages, make handlers uniform.
The current code sends hsmstatus_client_bad_request via the req fd;
this won't work, since lightningd uses that synchronously and only
expects a reply to its commands.  So send it via status_conn.

We also enhance hsmstatus_client_bad_request to include details, and
create convenience functions for it.  Our previous handling was ad-hoc;
we sometimes just closed on the client without telling lightningd,
and sometimes we didn't tell lightningd *which* client was broken.

Also make every handler the exact same prototype, so they now use the
exact same patterns (hsmd *only* handles requests, makes replies).

I tested this manually by corrupting a request to hsmd.

And delete unused gossipd/gossip.h.
