Jonas 'Sortie' Termansen d189183900 Third generation Tix.
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.
