Dmitry kindly measured the effect of my changes, and they were not
quite satisfactory, so I have now committed a simpler and more
efficient version of read_avail_input, which uses a much smaller
input_event buffer (8 instead of 4096 elements) when read_socket_hook
is used, and just a single input_event otherwise.

My own subjective feeling is that emacs is now more responsive, especially
when resizing the frame or dragging a mode line with the mouse.
