Modified Files:
        syssrc/sys/kern [kqueue]: kern_event.c

Log Message:
* update for differences between netbsd & freebsd WRT:
        - header files
        - struct locking
        - pool (& other memory) allocation
        - timeouts
* add kqueue_ioctl(), to support ioctl(2) operations on a kqueue fd.
* change the way that system filters are referenced to support name lookups
  and unimplemented (yet known about) filter types (such as EVFILT_AIO)
* add kfilter_register(9): register filter with given name to map to given
  filterops. filter must not exist
* add kfilter_unregister(9): unregister user filter
* add kfilter_byname(): lookup filter by name, which can be a system filter
  or a user-added filter
* add kfilter_byfilter(): lookup filter by filter number
* in kqueue_register(), use kfilter_byfilter() to determine filterops rather
  than using obscure ~ operation (which was now incorrect due to renumbering)
* cleanup whitespace, improve comments
* check return code of all copyouts()s
