I decided to make an attempt and it turned out making a new
function called curl_multi_poll() that does exactly this requried a *minimal*
change:

   https://github.com/curl/curl/pull/2415

There's no docs and no tests or anything but I'm interested in thoughts and
feedback. It basically acts exactly like curl_multi_wait, *but* if there's
nothing to wait for it will wait for the timeout period (or shorter if the
multi handle as a timeout set that expires before the given timeout).

If we are to add a new function, we might as well make sure that we correct
all the problems we can think of while at it!

An alternative design could be to add a curl_multi_setopt() option that
changes how curl_multi_wait() behaves, but I figure that is slightly more
subtle...
