	* connq.h (struct connq_request): Remove forward.
	(connq_listen): Wait for a request to be queued not until there is
	a connection attempt.  Remove REQ parameter.  Update callers.
	(connq_request_complete): Remove declaration.
	(connq_connect): Wait for a slot to queue a request not until
	there is an acceptor.  Remove SOCK parameter.  Update callers.
	(connq_connect_complete): New declaration.
	(connq_connect_cancel): New declaration.

	* connq.c (struct connq): Remove fields noqueue, queue, length,
	head and tail.  Add fields head, tail, count, max, connectors and
	num_connectors.  That is, replace the circular buffer with a
	singly linked list.
	(qnext): Remove function.

	(connq_request_complete): Remove function.
	(connq_connect): Rewrite to not block until there is an acceptor
	but until there is space for a request.
	(connq_connect_complete): New function.
	(connq_connect_cancel): New function.
