Emilio Cobos Álvarez 791917d8af Bug 1976665 - Sort headers in dom/. r=dom-core,media-playback-reviewers,webrtc-reviewers,dom-storage-reviewers,padenot,janv,smaug,jesup,jib
Most changes are automated. Relevant bit is dom/.clang-format. I had to
manually disable clang-format in a few places where importing external
files and so on that aren't self-contained, and fix a couple includes /
forward declarations.
