DirectoryWatcher transmits messages from a filesystem server about events happening in the filesystem. Clients can register new watchers using the `Directory.Watch` method, where they can filter which events they want to receive notifications for. The DirectoryWatcher will send messages of the form: ``` struct { uint8 event; uint8 len; char name[]; }; ``` Where names are NOT null-terminated. The name is the relative path to the entry the event is refering to. It will be empty if the event isn't referencing a particular entry (e.g. for the `IDLE` event).
