With the new InodeWatcher API, the old style of creating a watcher per
inode will no longer work. Therefore the FileWatcher API has been
updated to support multiple watches, and its users have also been
refactored to the new style. At the moment, all operations done on a
(Blocking)FileWatcher return Result objects, however, this may be
changed in the future if it becomes too obnoxious. :^)

(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)
Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.
We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.
This wrapper abstracts the watch_file setup and file handling, and
allows using the watch_file events as part of the event loop via the
Core::Notifier class.
Also renames the existing DirectoryWatcher class to BlockingFileWatcher,
and adds support for the Modified mode in this class.
