This looks reasonable. However, eloop_win.c and eloop_none.c will also
need to be modified to define the new eloop function to avoid breaking
the Windows build and template eloop implementation. I did not test
this, but I would assume that eloop_is_timeout_registered() can simply
be copied as-is to the other eloop implementations since all of them
share very similar data structure for timeouts.
