I tried to just do gossipd, but it was uncontainable, so this ended up being
a complete sweep.
We didn't get much space saving in gossipd, even though we should save
24 bytes per node.

We couldn't use it before because it asserted dbid was non-zero. Remove
assert and save some code.

Header from folded patch 'fixup!_lightningd__use_hsm_get_client_fd()_helper_for_global_daemons_too.patch':
fixup! lightningd: use hsm_get_client_fd() helper for global daemons too.

I crashed the HSMD, and it gave no output at all. That's because we
were only reading the status fd when we were waiting for a reply.
Fix this by using a separate request fd and status fd, which also means
that hsm_sync_read() is no longer required.

Originally we were supposed to tell the HSM we had just created the directory,
otherwise it wouldn't create a new seed. But we modified it to check if
there was a seed file anyway: just move that logic into a branch of hsmd.

Now we're always sync, just use an fd. Put the hsm_sync_read() helper
here, too, and do HSM init sync which makes things much simpler.
