Provide a new interface for the user of aio_read() and aio_write() to request
a kevent upon completion of the I/O.  Specifically, introduce a new type
of sigevent notification, SIGEV_EVENT.  If sigev_notify is SIGEV_EVENT,
then sigev_notify_kqueue names the kqueue that should receive the event
and sigev_value contains the "void *" is copied into the kevent's udata
field.

In contrast to the existing interface, this one: 1) works on
the Alpha 2) avoids the extra copyin() call for the kevent because all
of the information needed is in the sigevent and 3) could be
applied to request a single kevent upon completion of an entire lio_listio().
