For now, we will just test for normal features, later on it'll be added
back.

Both run-set_alloc and run-15-timeout used the same port, so they sometimes
got stuck when running in parallel.

Apparently init --user adopts orphans.  To quote the author

Trivial, but they make coding easier and more predictable.

MSVC only supports inline assembly and does not support the keyword
volatile for assembly.

This is a much more cleaner way to do it and _should_ be easier for people
to use.

I really wanted an array of bytes in there, so make it more flexible.

Not a perfect solution (we'd ideally want to go to another plan
immediately, but that would involve a malloc).

Don't call through io_loop, but have it pass the connection back
and call manually.

Don't call from the plan-construction function, call after it returns.

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.

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.

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.
