Require new libuEV API: uev_init1() to enforce a small event cache

In cases where you have multiple events pending in the cache and some
event may cause later ones, already sent by the kernel to userspace,
to be deleted the pointer returned to the event loop for this later
event may be deleted.

There are two ways around this (accessing deleted memory); 1) use this
function to initialize your event loop and set maxevents to 1, 2) use a
free list in you application that you garbage collect at intervals
relevant to your application.
