svn commit: r336457 - head/sys/sys

Log:
  Make the definition of struct kevent in event.h match what the man page for kevent(2) says.
  
  This is a trivial comment-only fix. The man page for kevent(2) gives
  the definition of struct kevent, including a comment on each
  field. The actual definition in sys/event.h omitted the comments on
  some fields. Add the comments in. Not only does this make the man page
  and include file agree, but the comments are useful in and of
  themselves.
