This patch does several things: - restores DEPTH and relativesrcdir in browser/components/safebrowsing, as they were reverted during the backout of bug 778608 - use @relativesrcdir@ in dom/devicestorage/test/Makefile.in, where the value was dom/devicestorage/test/ (@relativesrcdir@ would be the same value, without the last slash) - use @DEPTH@ in a newly added file (bug 749257) - fix relativesrcdir by using @relativesrcdir@ in various mobile branding directories - use @DEPTH@ under xpfe/components/autocomplete, now that c-c has a port of bug 774032. The Makefiles are generated by c-c configure and the depth is relative to the c-c topsrcdir, which is why it wasn't possible to change them before. Using @DEPTH@ now also means that nothing will have to change when c-c switches to building under the mozilla topsrcdir.
