Subject: unit: Move UnitType definitions from core/unit.c to shared/unit-name.c
X-Git-Tag: v187~147
X-Git-Url: http://www.chiark.greenend.org.uk/ucgi/~ianmdlvl/git?p=elogind.git;a=commitdiff_plain;h=0a9f8ed00c8f323d5bf24a9a11149a9342c0e1aa

unit: Move UnitType definitions from core/unit.c to shared/unit-name.c

This makes it possible to use them from systemctl without linking
against the core. A string->enum lookup table is added.
