Makefiles so that we can make changes to it centrally as needed and have
less mess. Fixes the sun2 build that needs rumpvfs after librump after
the latest changes.
This enables us to remove custom Atffiles whose only purpose was to avoid
using the helpers as tests.
XXX src/tests/dev/dm/ is not (yet) linked into the build!
- The use.fs property is gone.
- Mark the tests/fs/t_create:attrs test as broken when using the default
unprivileged-user:_atf setting. This probably deserves a fix somehow
but I'm not sure at this point.
and dm_targets_list ioctl to test if dm driver inside rump works.
It will be disable for now, because I need to find out why if I run this
test by atf-run it fails while running h_dm by hand works.
XXX. component.c in rump/libdm calls devsw_attach before dm_modcmd can do
that therefore unmodified modcmd returns error.
