bcd8e6d1bd local: fix memory leak when putting together locale settings
Also, we need to use proper strv_env_xyz() calls when putting together
the environment array, since otherwise settings won't be properly
overriden.

And let's get rid of strv_appendf(), is overkill and there was only one
user.

a6fde35332 systemd-run: properly escape arguments
Spaces, quotes, and such, were not properly escaped. We should
write them like we read them.

e21fea24ae rework systemd's own process environment handling/passing
Stop importing non-sensical kernel-exported variables. All
parameters in the kernel command line are exported to the
initial environment of PID1, but suppressed if they are
recognized by kernel built-in code. The EFI booted kernel
will add further kernel-internal things which do not belong
into userspace.

The passed original environ data of the process is not touched
and preserved across re-execution, to allow external reading of
/proc/self/environ for process properties like container*=.

44a6b1b680 Add __attribute__((const, pure, format)) in various places
I'm assuming that it's fine if a _const_ or _pure_ function
calls assert. It is assumed that the assert won't trigger,
and even if it does, it can only trigger on the first call
with a given set of parameters, and we don't care if the
compiler moves the order of calls.

b231b54780 Remove erroneous attribute((malloc)) annotations
According to gcc documentation, returned pointer "cannot alias any
other pointer valid when the function returns" and "the memory has
undefined content". This second part is (hopefully) untrue for all
those functions.

dfb33a9737 macro: rework how we define cleanup macros
There's now a generic _cleanup_ macro with an argument. The macros for
specific types are now defined using this macro, and in the header files
where they belong.

All cleanup handlers are now inline functions.

4468addca6 journalctl: give a nice hint about group membership based on ACLs of /var/log/journal
If we notice that we unprivileged and not in any of the groups which
have access to /var/log/journal, print a nice message about which groups
do.

This checks and prints all groups that are in the default ACL for
/var/log/journal, which is not necessarily correct for all journal
files, but pretty close.

26d04f86a3 unit: rework resource management API
This introduces a new static list of known attributes and their special
semantics. This means that cgroup attribute values can now be
automatically translated from user to kernel notation for command line
set settings, too.

This also adds proper support for multi-line attributes.

fabe5c0e5f binfmt,tmpfiles,modules-load,sysctl: rework the various early-boot services that work on .d/ directories
This unifies much of the logic behind them:

- All four will now ofllow the rule that the earlier file and earlier
  assignment in the .d/ directories wins. Before, sysctl was the only
  outlier, where the later setting always won.

- All four now support getopt() and --help on the command line.

- All four can now handle specification of configuration file names on
  the command line to apply. The tools will automatically find them, and
  apply them. Previously only tmpfiles could do that. This is useful for
  %post scripts in RPMs and suchlike.

- This fixes various error path issues in conf_files_list()

4d1a690438 env: considerably beef up environment cleaning logic
Now, actually check if the environment variable names and values used
are valid, before accepting them. With this in place are at some places
more rigid than POSIX, and less rigid at others. For example, this code
allows lower-case environment variables (which POSIX suggests not to
use), but it will not allow non-UTF8 variable values.

All in all this should be a good middle ground of what to allow and what
not to allow as environment variables.

(This also splits out all environment related calls into env-util.[ch])

6d0274f115 timedatectl: introduce new command line client for timedated
Much like logind has a client in loginctl, and journald in journalctl
introduce timedatectl, to change the system time (incl. RTC), timezones
and related settings.

c2f1db8f83 use #pragma once instead of foo*foo #define guards
#pragma once has been "un-deprecated" in gcc since 3.3, and is widely supported
in other compilers.

I've been using and maintaining (rebasing) this patch for a while now, as
it annoyed me to see #ifndef fooblahfoo, etc all over the place,
almost arrogant about the annoyance of having to define all these names to
perform a commen but neccicary functionality, when a completely superior
alternative exists.

I havn't sent it till now, cause its kindof a style change, and it is bad
voodoo to mess with style that has been established by more established
editors. So feel free to lambast me as a crazy bafoon.

v2 - preserve externally used headers

07719a21b6 manager: rework generator logic
Previously generated units were always placed at the end of the search
path. With this change there will be three unit dirs instead of one, to
place generated entries at the beginning, in the middle and at the end
of the search path:

beginning: for units that need to override all configuration, regardless
of user or vendor. Example use: system-update-generator uses this to
temporarily redirect default.target.

middle: for units that need to override vendor configuration, but not
vendor configuration. Example use: /etc/fstab should override vendor
supplied configuration (think /tmp), but should not override native user
configuration.

end: does not override anything but is available as well. Possible usage
might be to convert D-Bus bus service files to native units but allowing
vendor supplied native units to win.

5430f7f2bc relicense to LGPLv2.1 (with exceptions)
We finally got the OK from all contributors with non-trivial commits to
relicense systemd from GPL2+ to LGPL2.1+.

Some udev bits continue to be GPL2+ for now, but we are looking into
relicensing them too, to allow free copy/paste of all code within
systemd.

The bits that used to be MIT continue to be MIT.

The big benefit of the relicensing is that closed source code may now
link against libsystemd-login.so and friends.
