This caused us to lose our gn check certification. :( Turns out gn check was just ignoring all the header paths it didn't understand and so gn check passing for sky wasn't meaning much. I tried to straighten out some of the mess in this CL, but its going to take several more rounds of massaging before gn check passes again. On the bright side (almost) all of our headers are absolute now. Turns out my script (attached to the bug) didn't notice ../ includes but I'll fix that in the next patch.
