e5d5edc3ff nss-mymachines: initialize logging 
No logging is done directly by nss-mymachines.c code, but we call into sd-bus,
which will log.

55679e291c nss-resolve: initialize logging, log json errors 
When the .so module is loaded, it gets a separate copy of stuff in src/basic,
including the log level variables. So any logging settings are unaffected by
the loading program calling log_parse_environment() or such. Let's also parse
the environment here so that we can have nice logging.

Initialization is done from each exported function, and pthread_once_t is used
to avoid duplicate initialization. I didn't merge PROTECT_ERRNO into
NSS_ENTRYPOINT_BEGIN because UNPROTECT_ERRNO is called in a bunch of places
and it would feel strange to have PROTECT_ERRNO hidden, but not UNPROTECT_ERRNO.

The most interesting stuff in this module is the varlink messages, and any
potential errors in json. So let's enable json logging when debug messages are
enabled.

With those changes, figuring out the issue in
https://github.com/systemd/systemd/pull/17823 is trivial:

d401a5e411 json: log location also when there is no file 
E.g. in nss-resolve it is still useful to print the location of the error:
src/test/test-nss.c:231: dlsym(0x0x1dc6fb0, _nss_resolve_gethostbyname2_r) → 0x0x7fdbfc53f626
(string):1:40: JSON field ifindex is out of bounds for an interface index.

I opted to use a partially duplicated if condition to avoid nesting. It's nice
to have the log calls vertically aligned. The compiler will optimize this nicely.

ee2812da8f mkosi: Enable --qemu-headless option for all distros 
--qemu-headless configures the generated image and mkosi's qemu
command to connect to the VM via the serial port. This allows
spawning a qemu VM within the user's terminal instead of spawning
a graphical GTK GUI. --qemu-headless sets TERM, COLUMNS and LINES
in serial-getty@ttyS0.service in the container which makes the
terminal in the VM behave almost equivalent to the one on the host.

This change makes testing changes to systemd using mkosi + QEMU a
lot easier compared to before as commands can be executed in the VM
from the comfort of one's terminal compared to the Linux console
available when running via the GTK GUI.

88fc9c9bad systemd-nspawn: Allow setting ambient capability set 
The old code was only able to pass the value 0 for the inheritable
and ambient capability set when a non-root user was specified.

However, sometimes it is useful to run a program in its own container
with a user specification and some capabilities set. This is needed
when the capabilities cannot be provided by file capabilities (because
the file system is mounted with MS_NOSUID for additional security).

This commit introduces the option --ambient-capability and the config
file option AmbientCapability=. Both are used in a similar way to the
existing Capability= setting. It changes the inheritable and ambient
set (which is 0 by default). The code also checks that the settings
for the bounding set (as defined by Capability= and DropCapability=)
and the setting for the ambient set (as defined by AmbientCapability=)
are compatible. Otherwise, the operation would fail in any way.

Due to the current use of -1 to indicate no support for ambient
capability set the special value "all" cannot be supported.

Also, the setting of ambient capability is restricted to running a
single program in the container payload.

7e0079f95f Make support for nscd flushing optional 
Fedora will deprecate support for nscd in the upcoming release [1] and plans to
drop it in the next one [2]. At that point we might as well build systemd
without that support too, since there'll be nothing to talk too.
