This allows detailed reporting where a tevent_req spends its time

We have the same information available under req->internal.private_type.
This way it's possible to call tevent_req_print() after
tevent_req_received() was called.

It's verify useful when debugging code without a debugger to
be able to use tevent_req_print() in DEBUG statements.

This is one of or hottest code paths, I think every bit counts here.

Note that some callers used their own destructor for their
tevent_req instance, they'll just overwrite this,
which is not intended, but works without problems.
The intended way is to specify a cleanup function
and handle the TEVENT_REQ_RECEIVED state as destructor.
Note that the TEVENT_REQ_RECEIVED cleanup event might
be triggered by an explicit tevent_req_received()
in the _recv() function. The TEVENT_REQ_RECEIVED event
is only triggered once as tevent_req_received()
will remove the destructor.
So the difference compared to a custom destructor
is that the struct tevent_req itself can continue
to be there, while tevent_req_received() removed
all internal state.

This makes sure we call tevent_req_received(req) on talloc_free()
and cleanup things in a defined order.

As we might defer the callback with tevent_req_defer_callback()
when calling tevent_req_done(), we should cancel the timeout directly.

This is very useful to find bugs.
You can use 'p *req' in gdb to show where
tevent_req_done(), tevent_req_error() or tevent_req_nomem()
was called.

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.
