The new idle watcher was temporarily disabled in 073a48d due to some semantic
incompatibilities with the previous implementation. This commit resolves those
issues and reactivates the new implementation.
One outstanding bug is that idle watchers can run in a different order
(relative to other handle types) than the old implementation, e.g. (timer, idle)
instead of the expected (idle, timer). This will be fixed in an upcoming commit.
