Tests are modified to check behaviour with relax and without relax.
New tests are added for hostname_cleanup().
Tests are moved a new file (test-hostname-util) because there's
now a bunch of them.
New parameter is not used anywhere, except in tests, so there should
be no observable change.
free() cannot be used with const pointers. However, our _cleanup_free_
handler features cast logic that hides that qualifier, so we don't get a
warning.
This adds a "char *extra" parameter to tempfn_xxxxxx(), tempfn_random(),
tempfn_ranomd_child(). If non-NULL this string is included in the middle
of the newly created file name. This is useful for being able to
distuingish the kind of temporary file when we see one.
This also adds tests for the three call.
For now, we don't make use of this at all, but port all users over.
This also adds "machinectl import-raw" and "machinectl import-tar" to
wrap these new bus calls.
THe commands basically do for local files that "machinectl pull-raw" and
friends do for remote files.
