SH-3244 Syscall avoidance in HttpRequest::update() method

Well, achieved that by doing work in bulk when needed.  But
turned into some additional things.  Change timebase from
mS to uS as, well, things are headed that way.  Implement
an HttpReplyQueue::fetchAll method (advertised one, hadn't
implemented it).
