a3d3bf559c fuzz: don't panic without a C++ compiler
meson's `cpp_args` option is defined only if it detects a C++ compiler,
otherwise we get an error:

../test/fuzz/meson.build:56:28: ERROR: Tried to access unknown option 'cpp_args'.

17ee59c9c9 fuzz: pass -Dc_args=/-Dcpp_args= to fuzzer targets
Prompted by #29972, because right now it's practically impossible to pass
-fno-sanitize=function to the fuzzer targets without some extensive
sed'ing.

This splits both c_args and cpp_args to separate arguments for
tools/meson-build.sh, because the other way would be to use `eval`, so
the space-separated but quoted strings passed to these options are not
split where they shouldn't, and I'd rather avoid using `eval` if
possible.

Also, this switches the positional arguments we pass to `meson setup`,
as they were in incorrect order (docs say it should be buildir followed
by sourcedir); meson is apparently clever enough to figure this out and
switch the arguments around if necessary, so it didn't complain.

725e646854 meson: generate proper version tag when git fails on permission errors
When building with mkosi I would get the following:

    [1/477] Generating version.h with a custom command
    fatal: detected dubious ownership in repository at '/work/src'
    To add an exception for this directory, call:

            git config --global --add safe.directory /work/src

and then the tag would be generated as 'v254-'. This is obviously some problem
with the setup, but we should handle this gracefully. Let's fall back to 'v254'
instead.

In the case where we have a repo but no tags, use --dirty=^ too, as in the case
with tags.

I tested four cases:
- normal checkout
- checkout with .git removed
- checkout with .git chowned to root
- checkout wiht all tags removed

3c1f396f69 man: support multiple versions of the documentation on the website
This changes the doc-sync meson target from a simple rsync command to a
script that:

* puts the documentation in a subdirectory according to the version
* injects a bit of javascript to add a drop-down to switch between versions
* updates an index.json file with the newly uploaded version
* keeps the latest/ directory up to date with the latest version
* supports a --no-latest switch to be used when uploading older versions

3691e7fce7 man: add checks for missing version information
This adds a new script tools/check-version-history.py and a corresponding
test when building in developer mode. It checks manpages (except dbus
documentation which is handled by update-dbus-docs) for missing version
history information.

It also adds ignore lists based on version 183 (the version that our version
annotations go back to). These can be augmented if we want to ignore other
elements if it doesn't make sense for them to have version annotations.

898e9edc46 elf2efi: Add --copy-sections option
This makes the special PE sections available again in our output EFI
images.

Since the compiler provides no way to mark a section as not allocated,
we use GNU assembler syntax to emit the sections instead. This ensures
the section data isn't emitted twice as load segments will only contain
allocating input sections.

142f0c61a3 elf2efi: Rework ELF section conversion
The main reason we need to apply a whole lot of logic to the section
conversion logic is because PE sections have to be aligned to the page
size (although, currently not even EDK2 enforces this). The process of
achieving this with a linker script is fraught with errors, they are a
pain to set up correctly and suck in general. They are also not
supported by mold, which requires us to forcibly use bfd, which also
means that linker feature detection is easily at odds as meson has a
differnt idea of what linker is in use.

Instead of forcing a manual ELF segment layout with a linker script we
just let the linker do its thing. We then simply copy/concatenate the
sections while observing proper page boundaries.
Note that we could just copy the ELF load *segments* directly and
achieve the same result. Doing this manually allows us to strip sections
we don't need at runtime like the dynamic linking information (the
elf2efi conversion is effectively the dynamic loader).

Important sections like .sbat that we emit directly from code will
currently *not* be exposed as individual PE sections as they are
contained within the ELF segments. A future commit will fix this.

1a71ac07ad meson: restore tools/meson-vcs-tag.sh
This conceptually reverts e95acdfe1d,
but the actual contents of the script are taken from the command invocation
in meson with all the updates that happened in the meantime.

One small change is that I replaced () by {}: this avoids one subprocess spawn.
People were worried about the cost of vcs_tag(), and this microoptimization may
help a bit. I measured the speed on machine, and noop rebuilds are still about
100–120 ms.

The logic is entirely moved to the script. This makes the meson config simpler
and also makes it easier to use it externally.

The script is needed for in-place rpm builds, see README.build-in-place.md [1],
where it is invoked from the spec file to determine the project version.

7f9a0d6d74 meson: Drop skip-deps option
Now that we use meson feature options for our dependencies, we can just
rely on '--auto-features=disabled' to do the same. One benefit of this
is that specific features can still be force-enabled by overriding it
with the appropriate '-Dfeature=enabled' flag.

The two remaining uses for skip-deps can simply rely on their default
logic that sets the value to 'no' when the dependency is disabled.

bd2f6a568d tools: update-hwdb-autosuspend.sh: Point at HEAD, not master branch
Many Chromium projects have moved from 'master' to 'main', where
'master' is no longer updated. Point at HEAD instead, which should
always represent the default branch.

I don't actually rerun/regenerate the database, since I don't really run
systemd environments to test that update on.

9289e093ae meson: use install_emptydir() and drop meson-make-symlink.sh
