Add Compression={none,xz} and CompressionLevel=0-9 settings. Defaults
are xz/6.
Compression=filesystem may be added later.
I picked "xz" for the compression "type", since we might want to add
different compressors later on. XZ is fairly memory and CPU intensive, and
embedded users will likely want to use LZO or some other lightweight compression
mechanism.
Unfortunately the core is first written uncompressed, then compressed
by reading from disk and writing to the output file. This is ugly and
slow, but I don't see a way around, if we want to get the backtrace
without keeping everything in memory.
When running in 'quiet' mode, the only message printed from shutdown
binary would be 'Cannot finalize remaining file systems and devices,
giving up.', the only log line at error level before switch back to
initramfs. This is misleading, because in initramfs everything will
be cleaned up properly.
Avoid printing anything at error level before the attempt to switch
back to initramfs. Rework the messages to contain a bit more
information what is still remaining, to help people diagnose shutdown
issues.
Kernel mangles comm information in an irreversible way when comm
constains repeated spaces. Retrieve comm information from /proc, and
only fallback to the information provided on the commandline when
retrieving information from /proc fails.
cryptsetup: don't add unit dependency on /dev/null devices when it is listed as password file
As special magic, don't create device dependencies for /dev/null. Of
course, there might be similar devices we might want to include, but
given that none of them really make sense to specify as password source
there's really no point in checking for anything else here.

build-sys: require elfutils >= 158
The recently added stacktrace support in 8d4e028f uses functions added
in elfutils 158. Check for one of the new functions to avoid attempting
to build against older versions.
shifting from a non fixed number of bits >= to the size of the type
leads to weird results, handle the special case of << 32 to fix it.
This was causing a test failure from test-socket-util:
Assertion 'in_addr_prefix_intersect(f, &ua, apl, &ub, bpl) == result' failed at
/var/tmp/paludis/build/sys-apps-systemd-scm/work/systemd-scm/src/test/test-socket-util.c:147, function

sd-dhcp-server: change default lease time form 1m to 1h
The short lease was useful for testing, but in real-world usage it is pointless to keep leases
this short. That said, the cost of lease renewal is really low, so we keep the lease still
relatively short at one hour to not get into hard-to-hit problems with lease exhaustion etc.
We used to check if e.g. IFLA_BOND_MAX is defined and provide fallback
values in missing.h is it wasn't. But over time, various kernel
versions added IFLA_* defines, so checking for IFLA_BOND_MAX is not
enough if the kernel is new enough to have some of them but too old to
have all. In case we detect that the latest known enum value is
missing, #define most of them.
build-sys: check that python is enabled for "make dist"
Running "make dist" requires Python support since some of the man page sources
(such as man/systemd.index.xml and man/systemd.directives.xml) are generated by
Python scripts, so break "make dist" and give an useful error message when
Python or the Python lxml module is not available.
Tested:
$ ./configure --without-python && make && make dist
*** python and python-lxml module must be installed and enabled in order to make dist
make: *** [dist-check-python] Error 1
build-sys: do not include id128-constants.h in the dist archive
File src/python-systemd/id128-constants.h is auto generated and its generation
does not require special tools, only sed. There is no point in bundling it in
the distribution archive, so let's mark it as nodist_ to have it excluded.
Fixes: https://bugs.freedesktop.org/show_bug.cgi?id=80006
Tested: Successfully ran "make dist" after ./configure --without-python.
There's no need to save the old sigmask, if we are going to die. Let's
simplify this. Also, reset all the signal handlers, so that we don't
leave SIG_IGN set for some of them across reexec.
build-sys: add sysusers.d/systemd.conf to CLEANFILES
The sysusers.d/systemd.conf configuration file was originally introduced in
commit 1b99214789101, but it was not marked for cleanup. This caused distcheck
to complain about the file not being removed by distcleam.
Tested: Successfully ran "make distcheck" with this patchset.

conf-files: include root in returned file paths
This restores the original root handling logic that was present prior to 112cfb18 when path expansion moved to path_strv_canonicalize_absolute.
That behavior partially went away in 12ed81d9.
Alternatively all users of conf_files_list* could be updated to
concatenate the paths themselves as unit_file_query_preset did but since
no user needs the un-concatenated form that is pointless duplication.
Since 12ed81d9 path_strv_canonicalize_absolute leaves the search list
relative to the given root directory instead of resolving paths to their
true location as the name implies. To better reflect this behavior
rename to the less strongly worded path_strv_resolve.
Otherwise the add_symlink() function tries to make directories for
each slash even for the slash after the @ symbol in the final link
name, failing for /dev/3270/tty1.
units/systemd-sysctl.service.in: run after load-modules
Modules might or will register new sysctl options.
[zj: This mechanism of adding modules just to reliably set sysctl
attributes is not ideal. Nevertheless, sysctl for dynamically created
attributes is simply broken, and this is the easiest workaround.]
