Summary: This commit doesn't change license of any file. It just makes the license implicit (inherited from LICENSE file in the root directory). We are removing the headers for these reasons: - It wastes space in editors, less code is visible in editor upon opening a file. - It brings noise to diff of the first change of any file every year. - It confuses Git file copy detection when creating small files. - We don't have an explicit license header in other files (JS, CSS, images, documentation). - Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new. This change is approved by Alma Chao (Lead Open Source and IP Counsel at Facebook). Test Plan: Verified that the license survived only in LICENSE file and that it didn't modify externals.
