— Move all macros from OFObject.h to macros.h
This means that OFObject.h imports macros.h now, making it unnecessary
to manually import macros.h in almost every file. And while at it, also
import autorelease.h in OFObject.h, so that this doesn't need to be
manually imported in almost every file as well. (user: js, size: 2697) [annotate] [blame] [check-ins using]
