Eric Seidel e0fd75b5ab Make absolute and sort all Sky headers
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.
