sd-bus for compat with old C expects "int" for booleans. Internally we
prefer to use C99 "bool" however. When pointing a pointer to it, we need
to handle the fact that they are typically differently sized, hence use
te right accessors for it.
The value is used as a boolean, but stored in an unsigned. It's exposed
with sd-bus default boolean handling which however expects a (signed)
int. Let's clear this up, and use "bool" for this everywhere in
non-local scope, and make sure that when we pass it to sd-bus we
properly pass an "int".
This reverts commit 0ad4efb14b.

Fixes regression introduced in 599be274c1
Moving the Xen check before the CPUID check, in order to handle the case where
a Xen domain is nested within a hypervisor which can be detected by via the
CPUID check, had an unintended consequence of causing Dom0 to report as a Xen
VM when it is not nested.
This patch stops further checks once it has been determined that Dom0 is not
nested within another hypervisor, meaning that the non-nested case matches its
previous logic (where it does not report as a VM).
Also, tidy the conditionals for the Xen and UML checks by removing handling of
a VIRTUALIZATION_VM_OTHER result, which has no code path.
Fixes#22511
We would print "Setting NUMA policy to bind, with nodes .".
This is not very clear, change it to "… with nodes {}.".
Also use range formatting for masks to make output shorter.
It should make it easier to figure out what exactly services do there.
For example, with SYSTEMD_LOG_LEVEL=debug userdbd (v249) prints
```
varlink-5: New incoming message: {"method":"io.systemd.UserDatabase.GetUserRecord","parameters":{}}
```
before it crashes and systemd-resolved prints
```
varlink-21: New incoming message: {"method":"io.systemd.Resolve.ResolveAddress","parameters":{"address":[127,0,0,1],"flags":0,"ifindex":1000000,"family":0}}
```
and those messages are helpful (especially when scripts causing them
aren't clever enough to keep track of random stuff they send to systemd
:-))
If we assign our own test runner, passing arguments stops working
as unittest won't instantiate its own test runner after it parses
the arguments from sys.argv.
Consequence is that the tests will write to stderr now instead of
stdout since it doesn't seem possible to configure the stream that
unittest.main() will instantiate its test runner with so it'll
default to sys.stderr.
