The .tix.tar.xz binary package format now stores the contents in the root rather than the data/ subdirectory and the tix metadata now has the same layout as the loose files in /tix, such that a .tix.tar.xz package can simply be directly extracted into the filesystem. The /tix/manifest/ is now included in the binary package rather than being generated on installation. The /tix/collection.conf and /tix/tixinfo metadata files are now in the tix-vars(1) format in the style of port(5). The /tix/installed.list file has been removed since it isn't loose file compatible and one can list the /tix/tixinfo directory instead. The /tix/repository.list file has been removed since the feature is unused and doesn't match the future direction of tix. The kernel support for tix binary packages has been removed since it will simply install by extracting the tar archive into the root filesystem. Add the post-install sha256sum to the port version stamp.
