The names of drop-in files can be anything as long as they are suffixed in ".conf", hence don't be stricter than necessary when validating the names used in symlink chains of such drop-in files. Also, drop-in files should not be ale to change the type of unit file itself, i.e. not affect whether it is considered masked or an alias as a whole. This adds a flag SEARCH_DROPIN that is passed whenever we load a drop-in rather the main unit file, and in that case loosen checks and behaviour we otherwise enforce for the unit file itself. Specifically: 1. If SEARCH_DROPIN is passed we won't change the unit's info->type field anymore, as that field (which can be REGULAR, MASKED, SYMLINK) should not be affected by drop-ins, but only by the unit file itself. 2. If SEARCH_DROPIN is passed we will shortcut following of symlink chains, and not validate the naming of each element in the chain, since that's irrelevant for drop-ins, and only matters for the unit file itself. Or in other words, without this: 1. A symlink /etc/systemd/system/foobar.service.d/20-quux.conf → /dev/null might have caused the whole of foobar.service to be considered "masked". 2. A symlink /etc/systemd/system/foobar.service.d/20-quux.conf → /tmp/miepf might have caused the whole loading of foobar.service to fail as EINVAL, as "miepf" is not a valid unit name.
