Remove the eventqueue list and the ev_next pointers.
Those pointers were once used to maintain a complete list of
inserted IO and signal events. But such a list is now available by
walking over ev_io_map and ev_signal_map! So all they did was
require extra pointer operations to maintain, and extra 8-16 bytes
of storage in each struct event.
To be cowardly and keep the option of going back to having this
redundancy, I'm wrapping the removed code in a set of ifdefs.
This is a first cut; it needs cleanups and stress-testing!! In
particular, it just plain disables a couple of functions that could
probably be saved.
There seems to be a need for an evmap_{io,signal}_foreach() or something.
