Subject: package.bbclass: Split into two tasks, one which prepares the
 packages and then package_write which actually generates the packages. The
 two stage approach allows us to avoid circular dependency issues from classes
 like debian.bbclass. As the data being emitted into pkgdata/ changed, you
 need to either wipe tmp or rerun the do_package tasks (wipe the do_package
 stamps). Everything will repackage anyway due to the new task.
