We have a fair number of files that have a particular stale version of the MPL boilerplate. (It was probably originally correct, and then the official boilerplate changed, and the stale MPL boilerplate continued to propagate via copypasting from neighboring files into newly-added files.) This patch updates this stale MPL text (and *only* the MPL text) to the latest version, which can be found at https://www.mozilla.org/en-US/MPL/headers/ and https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line MozReview-Commit-ID: 8WeBb8b0uRo
