Fix incorrection assumption about the Debian patch being buggy and
actually making TEST-73-LOCALE fail on Debian.
```
# localectl set-locale LANG=C.UTF-8
# cat /etc/default/locale
LANG=C.UTF-8

Similary, this also renames context_free_x11() -> context_clear_x11(),
to make it clear that these functions do not free Context.
Also, this makes context_clear() support to be called more than once.
- add missing assertions,
- rename arguments for storing results,
- always initialize results on success,
- use _cleanup_ attribute at more places, etc.
We would set .path in all cases except INSTALL_CHANGE_AUXILIARY_FAILED, where
we would just just .source. This special case is just not worth it, because
we can't easily assert that .path is set. Let's remove this special case to
help the compiler know that .path is actually set.
Avoids a warning with gcc-13.0.1-0.1.fc38.x86_64.
Whether we use a newline at the beginning of <programlisting> or not doesn't
seem to have any effect. So let's use the newline in multi-line examples; it is
easier to get the indentation right this way.
Let's make sure the timestamp file's mtime is guaranteed to change for
each boot, so that it is a useful indicator of time. Or in other words
this gurantees that systemd-timesyncd.service acts as a new kind of
milestone: that time definitely progressed on this boot even the machine
died abnormally imediately after.
It's useful being able to easily detect if a disk-based clock bump was
done, let's make it a structure message, the same way as acquiring an
NTP fix already is.
Also, set the clock to 1 µs further than the timestamp from the disk,
after all we know that that timestamp was current when it was written,
hence it can't be the right one right now anymore.
If output fields are specified, let's store this in a Set right-away,
instead of converting between strv and Set again and again for each
line.
This is not only faster, but also simpler and shorter.
libefi.a just provided the c helper API that was slowly removed. As we
do not depend on anything provided by it anymore, it is safe to drop
now.
Since the ST/BS/RT pointers are very convenient and needed everywhere,
they are retained and initialized by us.
This stops using global GUID variables provided by gnu-efi. The globals
presumably exist to make EFI calls easier. But these GUIDs are just
128bits, so it's cheap to just put them on the stack when needed. C99
compound literals makes this even easier.
This also adds a convenience macro to create GUID pointers and uses it
everywhere. Not forcing a GUID definition to be a compound literal makes
them easier to use when assigning them to variables:
EFI_GUID before = *SOME_CONST_GUID;
EFI_GUID after = SOME_GUID;
And MAKE_GUID_PTR() makes it more explicit what is happening. It was
easy to confuse the old code as a cast:
before(&(EFI_GUID) SOME_GUID);
after(MAKE_GUID_PTR(SOME));
grub (at least on fedora) nowadays implements the boot loader spec, but
not the boot loader interface. Hence let's split out the commands
specific to each in two groups in the --help text. This way the first
group just covers boot lodaer spec stuff (i.e. stuff on disk in the
ESP/XBOOTLDR partition). And the other covers talking to the boot loader
via EFI var.
