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.
