91e0ee5f16 pid1: drop unit caches only based on mtime 
v2:
- do not watch mtime of transient and generated dirs

  We'd reload the map after every transient unit we created, which we don't
  need to do, since we create those units ourselves and know their fragment
  path.

e67cd21d7d analyze: add "unit-files" to dump the unit fragment map 
I'm not convinced that this is useful enough to be included... But it is
certainly nice when debugging.

e8630e6952 pid1: use a cache for all unit aliases 
This reworks how we load units from disk. Instead of chasing symlinks every
time we are asked to load a unit by name, we slurp all symlinks from disk
and build two hashmaps:
1. from unit name to either alias target, or fragment on disk
   (if an alias, we put just the target name in the hashmap, if a fragment
    we put an absolute path, so we can distinguish both).
2. from a unit name to all aliases

Reading all this data can be pretty costly (40 ms) on my machine, so we keep it
around for reuse.

The advantage is that we can reliably know what all the aliases of a given unit
are. This means we can reliably load dropins under all names. This fixes #11972.

7d1e91d1a9 shared/unit-file: add a function to validate unit alias symlinks 
It turns out most possible symlinks are invalid, because the type has to match,
and template units can only be linked to template units.

I'm not sure if the existing code made the same checks consistently. At least
I don't see the same rules expressed in a single place.

54f4403485 TEST-15-DROPIN: add test for details of unit aliasing 
I adjusted the tests to pass. I don't think the behaviour makes much sense,
even if we ignore the issue with "lazy loading" of aliases. E.g. in the
last section, the fact that dropins for yup@.service and yup@3.service are
not loaded seems to be a plain old bug.

976ed3b621 test: use "ln -fs" 
Without this, repeated runs of "make -C TEST/... setup" fail when trying
to create the symlink.

37109b856a pid1: use LOG_DEBUG/INFO/NOTICE for unit resource consumption message 
We now log at LOG_INFO for any unit. Let's vary the log level
a bit, so that for normal short lived-units (less than 1 sec CPU),
we only log if debugging is enabled.

148ffa2e4d systemctl: do print all statuses/signals received from pid1

right place to do value filtering for exit codes. If pid1 accepted it,
let's just print it with no fuss.
