The f'...' format was introduced in Python 3.6 ( https://www.python.org/dev/peps/pep-0498/ )
and returns an error when systemd is built on a system with an older Python3 version:
<...>
File /home/bluca/git/systemd/tools/make-autosuspend-rules.py, line 15
print(f'pci:v{vendor:08X}d{device:08X}*')

SyntaxError: invalid syntax
[2/388] Generating version.h with a custom command.
ninja: build stopped: subcommand failed.

Python 3.5.6
Use an older format to keep backward compatibility.
Concatenating strings is not a very efficient approach. And in this case fully
unnecessary. We also need some rules to make use of those hwdb entries.
PCI needs to be 8 characters, not 4. And we need to use uppercase hexadecimal
for both. With udev rules this made no difference, but hwdb match is case
sensitive.
Fixes#16119.
When directives-template.xml was created in 282230882c,
this generator started picking it up. Let's filter it out properly again,
and also simply the filter while at it.
I wasn't 100% convinced that this is the right thing to do, hence the separate
commit. But e.g. for paths we index all mentions, so I think it's reasonable to
do the same here.
The hack with getparent().txt is not very pretty, but the whole
thing seems to work well enough. It is useful to figure out whihc
specifiers are supported where.
In the beginning, it was rather short, and reasonable to include inline.
Now it is long and unwieldy, let's split it out.
While at it, let's reindent and wrap using our current standards.
The name of the helper didn't match the name of the meson target, which was
always confusing me. With this change, we consistenly use "update" to
re-generate things which we otherwise keep in vc, and "make" for things
which are generated during each build.
In a few cases, the prefix was originally necessary because a different helper
script was used for automake, and a different one for meson. But now we use
meson exclusively, and the prefix isn't useful. This also synchronizes the
target name, file name, and variable name in meson.build. The targets exposed
by meson didn't have the prefix, so the user interface is unchanged.
(The prefix is retained in the few tools that are used for meson itself,
e.g. meosn-vcs-tag.sh, meson-make-symlink.sh, etc.)
This commit looks for a new "extra-ref" attribute in <variablelist>
If this attribute is specified, its content will be index as pointing to
the current man-page in systemd.directives
So far, make-directive-index would look for
./valistentry/term/varname for elements to add to the directive man page.
This commit allows to specify xpath= in the varlist directive to tell
the generator what to look for.
