Remove file watcher code

Now that we refresh upon focus, we can scrap this file watching code.
Stefan says few git UIs use file watching, and I understand why: the
reason this code was problematic in the first place is that watching
files is expensive and if you have too many open file handles that
can cause problems.

Importantly: this code that's being removed was _already_ dead.

-# Contributing
-
-## Issues
-
-* Request features and report bugs using the [GitHub Issue Tracker](https://github.com/fsnotify/fsnotify/issues).
-* Please indicate the platform you are using fsnotify on.
-* A code example to reproduce the problem is appreciated.
-
-## Pull Requests
-
-### Contributor License Agreement
-
-fsnotify is derived from code in the [golang.org/x/exp](https://godoc.org/golang.org/x/exp) package and it may be included [in the standard library](https://github.com/fsnotify/fsnotify/issues/1) in the future. Therefore fsnotify carries the same [LICENSE](https://github.com/fsnotify/fsnotify/blob/master/LICENSE) as Go. Contributors retain their copyright, so you need to fill out a short form before we can accept your contribution: [Google Individual Contributor License Agreement](https://developers.google.com/open-source/cla/individual).
-
-Please indicate that you have signed the CLA in your pull request.
-
-### How fsnotify is Developed
-
-* Development is done on feature branches.
-* Tests are run on BSD, Linux, macOS and Windows.
-* Pull requests are reviewed and [applied to master][am] using [hub][].
-  * Maintainers may modify or squash commits rather than asking contributors to.
-* To issue a new release, the maintainers will:
-  * Update the CHANGELOG
-  * Tag a version, which will become available through gopkg.in.
- 
-### How to Fork
-
-For smooth sailing, always use the original import path. Installing with `go get` makes this easy. 
-
-1. Install from GitHub (`go get -u github.com/fsnotify/fsnotify`)
-2. Create your feature branch (`git checkout -b my-new-feature`)
-3. Ensure everything works and the tests pass (see below)
-4. Commit your changes (`git commit -am 'Add some feature'`)
-
-Contribute upstream:
-
-1. Fork fsnotify on GitHub
-2. Add your remote (`git remote add fork git@github.com:mycompany/repo.git`)
-3. Push to the branch (`git push fork my-new-feature`)
-4. Create a new Pull Request on GitHub
-
-This workflow is [thoroughly explained by Katrina Owen](https://splice.com/blog/contributing-open-source-git-repositories-go/).
-
-### Testing
-
-fsnotify uses build tags to compile different code on Linux, BSD, macOS, and Windows.
-
-Before doing a pull request, please do your best to test your changes on multiple platforms, and list which platforms you were able/unable to test on.
-
-To aid in cross-platform testing there is a Vagrantfile for Linux and BSD.
-
-* Install [Vagrant](http://www.vagrantup.com/) and [VirtualBox](https://www.virtualbox.org/)
-* Setup [Vagrant Gopher](https://github.com/nathany/vagrant-gopher) in your `src` folder.
-* Run `vagrant up` from the project folder. You can also setup just one box with `vagrant up linux` or `vagrant up bsd` (note: the BSD box doesn't support Windows hosts at this time, and NFS may prompt for your host OS password)
-* Once setup, you can run the test suite on a given OS with a single command `vagrant ssh linux -c 'cd fsnotify/fsnotify; go test'`.
-* When you're done, you will want to halt or destroy the Vagrant boxes.
-
-Notice: fsnotify file system events won't trigger in shared folders. The tests get around this limitation by using the /tmp directory.
-
-Right now there is no equivalent solution for Windows and macOS, but there are Windows VMs [freely available from Microsoft](http://www.modern.ie/en-us/virtualization-tools#downloads).
-
-### Maintainers
-
-Help maintaining fsnotify is welcome. To be a maintainer:
-
-* Submit a pull request and sign the CLA as above.
-* You must be able to run the test suite on Mac, Windows, Linux and BSD.
-
-To keep master clean, the fsnotify project uses the "apply mail" workflow outlined in Nathaniel Talbott's post ["Merge pull request" Considered Harmful][am]. This requires installing [hub][].
-
-All code changes should be internal pull requests.
-
-Releases are tagged using [Semantic Versioning](http://semver.org/).
