Both the scantool and dzcomm library were repacked from the upstream ZIP

files. When unpacking dzcomm, the "-a" unzip flags was used to fix text EOL

markers, since there are several shell scripts that would not run without

this change and providing a quilt patch to fix EOL markings would be crazy.

When repacking scantool, the "listports.{c,h}" files were removed since they

are non-free and not needed for the POSIX build.

The Allegro .dat files are just archives, like Tar.

The "scantool" data file contains resources for running the UI:

$ dat -l scantool.dat

The "codes" data file contains ODB-II scan codes, which are single-line,

tab-separate text fields:

$ dat -l codes.dat
