50e30afa60 s3: Fix bug 8385
Poll and select behave differently regarding error handling. When doing the
connect(2), we can not rely on poll telling us both readability and writability
upon error. Just always try a second connect(2). At least on Linux it returns 0
when it succeeded.

0efcc94fb8 Fix bug #8197 - winbind does not properly detect when a DC connection is dead.
Only waiting for writability doesn't get fd errors back with poll.
So always begin by selecting for readability, and if we get it then
see if bytes were available to read or it really is an error condition.

If bytes were available, remove the select on read as we know we
will retrieve the error when we've finished writing and start
reading the reply (or the write will timeout or fail).

Metze and Volker please check.

9de2efaa5b Change async_connect to use connect instead of getsockopt to get the error
On my Linux box, this is definitely the more reliable strategy with unix domain
sockets, and according to my tests it also works correctly with TCP sockets.

a8e02b591b Add "err_on_readability" to writev_send
A socket where the other side has closed only becomes readable. To catch
errors early when sitting in a pure writev, we need to also test for
readability.

fe486d7b9f Add "queue" to writev_send
Unless higher levels queue themselves somehow, writev will *always* be queued.
So the queueing should be done at the right level.

67d41d0fc7 Make struct tevent_req opaque
Move struct tevent_req in tevent_internal, and ad getters and setters
for private data and the callback function.
This patch also renames 'private_state' into 'data'. What is held in this
pointer is in fact data and not a state like enum tevent_req_state.
Calling it 'state' is confusing.

The functions addedd are:
tevent_req_set_callback() - sets req->async.fn and req->async.private_data
tevent_req_set_print_fn() - sets req->private_print
tevent_req_callback_data() - gets req->async.private_data
tevent_req_data() - gets rea->data

This way it is much simpler to keep API/ABI compatibility in the future.
