Without this, closing an fd results in a spin...

Overloading io_close() as a callback is ugly: create an explicit
io_close_cb().

Use a -1 for error codes.  This makes it easier to write your own io funcs.

Rather than insisting on supplying them on every call to io_new_conn().
Also, this way it can be changed on a connection.

And rename debug_io_plan() to io_plan_debug() so it can be exposed.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Debugging an async library is a pain: it's nice to force it into a
linear call chain to try to track problems.

Ugly code, though.

In particular, make sure that idle connections don't get closed.

Have it set the plan itself, rather than passing it back.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Pass fd and plan explicitly, so they don't need to know the definition
of struct io_conn, and return a bool instead of an enum.

Use a NULL next pointer instead to indicate a closing connection.

Use a NULL io pointer instead to indicate an idle connection.

It was only used for initial connections which hadn't started I/O.  Now
they are initialized with an io_plan, it can be eliminated.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

Rather than going via a callback, which tends to just set up I/O, do
any setup before the call to io_new_conn(), then pass it the io_plan
directly.

The patch shows how much this simplifies our test code.

Instead of assuming they want a connection made from the new fd, hand
the fd to a callback.

No longer needed.
Signed-off-by: Rusty Russell <rusty@rustcorp.com.au>

This simplifies some things: in particular, we can construct an
io_plan without needing the current io_conn.

On the other hand, we need to expose the structure now.

Explicit callbacks are slower, but more flexible.

Sure, both listener and conn need them, but for different things
(listener uses them simply to set up conn).  Putting them in the
common union was a mistake.

It's probably a bug if we're waiting for nothing.

The new functions are:

Also add more tests on how one would parse the low-level stuff.
