HTTP internals: do not open too many sockets when preconnecting

Each pair of (normal request, preconnect request) requires only one
socket. E.g. if there is 1 preconnect request in-flight and 2 normal
requests, we need only 2 sockets in total, and not 3.

Therefore, we need to keep track of whether a request is
preconnecting or a normal one.
