Subject: [PATCH 2/5] manager: fix a crash in isolating
HASHMAP_FOREACH is safe against the removal of the current entry, but
not against the removal of other entries. job_finish_and_invalidate()
can recursively remove other entries.
It triggered an assertion failure:
Assertion 'j->installed' failed at src/manager.c:1218, function
transaction_apply(). Aborting.
Fix the crash by iterating from the beginning when there is a
possibility that the iterator could be invalid.
It is O(n^2) in the worst case, but that's better than a crash.

Subject: [PATCH 5/5] systemctl-completion: always invoke with --no-legend
In the case of completion for the 'restart' verb, passing the invalid
unit name (the colums header) causes completion to cease functioning
entirely, with the error:
Failed to issue method call: Unit name UNIT is not valid.
This adds a small wrapper function for systemctl which can have common
options added to it.
