fsnotify contains code from https://github.com/golang/exp

Previously there was plans to incorporate fsnotify into the standard library and use it for tools such as the go command and godoc. #1

The LICENSE and CLA requirement in CONTRIBUTING are based on this.

However, I haven't been enforcing the CLA requirement on recent pull requests. A tool like CLAHub would help but its future is unknown. More importantly, I don't think fsnotify belongs in the standard library any longer. Using an internal/ package would allow the go command to use fsnotify (or an alternative) without exposing an API that must be locked down.

So I think it's time to make fsnotify its own project:

• The license is currently the same three clause BSD as Go with mention of Google. This could be changed to a simplified BSD license (2 clause).
• The license should continue to have the copyright to fsnotify authors.
• The header comments on .go files could be updated to fsnotify authors or simply removed.
• There should still a mention somewhere that fsnotify is derived from code that is Copyright (c) 2012 The Go Authors. All rights reserved.
• The CLA requirement could be dropped.
