Chris Dunlap 8c7aa0cfc4 Replace zpool_events_next() "block" parm w/ "flags"

zpool_events_next() can be called in blocking mode by specifying a
non-zero value for the "block" parameter.  However, the design of
the ZFS Event Daemon (zed) requires additional functionality from
zpool_events_next().  Instead of adding additional arguments to the
function, it makes more sense to use flags that can be bitwise-or'd
together.

This commit replaces the zpool_events_next() int "block" parameter with
an unsigned bitwise "flags" parameter.  It also defines ZEVENT_NONE
to specify the default behavior.  Since non-blocking mode can be
specified with the existing ZEVENT_NONBLOCK flag, the default behavior
becomes blocking mode.  This, in effect, inverts the previous use
of the "block" parameter.  Existing callers of zpool_events_next()
have been modified to check for the ZEVENT_NONBLOCK flag.
