core: move enforcement of the start limit into per-unit-type code again
Let's move the enforcement of the per-unit start limit from unit.c into the type-specific files again. For unit types that know a concept of "result" codes this allows us to hook up the start limit condition to it with an explicit result code. Also, this makes sure that the state checks in clal like service_start() may be done before the start limit is checked, as the start limit really should be checked last, right before everything has been verified to be in order. The generic start limit logic is left in unit.c, but the invocation of it is moved into the per-type files, in the various xyz_start() functions, so that they may place the check at the right location. Note that this change drops the enforcement entirely from device, slice, target and scope units, since these unit types generally may not fail activation, or may only be activated a single time. This is also documented now. Note that restores the "start-limit-hit" result code that existed before 6bf0f408e4833152197fb38fb10a9989c89f3a59 already in the service code. However, it's not introduced for all units that have a result code concept. Fixes #3166.
