The modernize documentation used to suggest -test flag but it's not
needed as it is enabled by default. Drop it.

Since we use modernize@latest, it may require latest Go as well (and now it does),
so use "go-version: stable" explicitly (which resolves to latest Go).
This fixes the issue with CI:
> go: golang.org/x/tools/gopls/internal/analysis/modernize/cmd/modernize@latest: golang.org/x/tools/gopls@v0.21.0 requires go >= 1.25 (running go 1.24.11; GOTOOLCHAIN=local)

Alas, these new constants are already in v1.4.0 release so we can't
remove those right away, but we can mark them as deprecated now
and target removal for v1.5.0.
So,
- mark them as deprecated;
- redefine via unix.MPOL_* counterparts;
- fix the validator code to use unix.MPOL_* directly.
This amends commit a0e809a8.

It appears that when we import github.com/coreos/go-systemd/activation,
it brings in the whole crypto/tls package (which is not used by runc
directly or indirectly), making the runc binary size larger and
potentially creating issues with FIPS compliance.
Let's copy the code of function we use from go-systemd/activation
to avoid that.
The space savings are:
$ size runc.before runc.after
text data bss dec hex filename
7101084 5049593 271560 12422237 bd8c5d runc.before

This function calls Init what normally never returns, so the defer only
works if there is an error and we can safely use it to close those fds
we opened. This was done for most but not all fds.
Reported in issue 5008.

Because we add the runc-$version/ prefix to the archive we generate,
including the version in the name makes it easier for some tools to
operate on as it matches most other projects (for openSUSE we rename the
archive file to this format in order for the automated RPM scripts to
work properly).
Also, when doing several releases at the same time, being able to
double-check that the correct artefact versions were uploaded for each
release can be quite handy.

Now that runc 1.4.0 has been released, there is no need to single out
1.1.x and earlier as no longer being supported, as latest-2 is now 1.2.x
and thus 1.1.x would no longer be supported even with the new support
model.

We have used this release policy for a year and it seems to work well
for everyone and we haven't received much feedback, so it seems
reasonable to say that we are committed to this policy now.

We intentionally broke this in commit d40b3439a9 ("rootfs: switch to
fd-based handling of mountpoint targets") under the assumption that most
users do not need this feature. Sadly it turns out they do, and so
commit 3f925525b4 ("rootfs: re-allow dangling symlinks in mount
targets") added a hotfix to re-add this functionality.
This patch adds some much-needed tests for this behaviour, since it
seems we are going to need to keep this for compatibility reasons (at
least until runc v2...).

While CreateInRoot supports hallucinating the target path, we do not use
it directly when constructing device inode targets because we need to
have different handling for mknod and bind-mounts.
The solution is to simply have a more generic MkdirAllParentInRoot
helper that MkdirAll's the parent directory of the target path and then
allows the caller to create the trailing component however they like.
(This can be used by CreateInRoot internally as well!)

In order to maintain compatibility with previous releases of runc (which
permitted dangling symlinks as path components by permitting
non-existent path components to be treated like real directories) we
have to first do SecureJoin to construct a target path that is
compatible with the old behaviour but has all dangling symlinks (or
other invalid paths like ".." components after non-existent directories)
removed.
This is effectively a more generic verison of commit 3f925525b4
("rootfs: re-allow dangling symlinks in mount targets") and will let us
remove the need for open-coding SecureJoin workarounds.

Now that MkdirAllInRoot has been removed, we can make MkdirAllInRootOpen
less wordy by renaming it to MkdirAllInRoot. This is a non-functional
change.

This probably should've been done as part of commit d40b3439a9
("rootfs: switch to fd-based handling of mountpoint targets") but it
seems I missed them when doing the rest of the conversions.
This also lets us remove utils.WithProcfd entirely, as well as
pathrs.MkdirAllInRoot. Unfortunately, WithProcfd was exposed in the
externally-importable "libcontainer/utils" package and so we need to
have a deprecation notice to remove it in runc 1.5.

These helpers will be needed for the compatibility code added in future
patches in this series, but because "internal/pathrs" is imported by
"libcontainer/utils" we need to move them so that we can avoid circular
dependencies.
Because the old functions were in a non-internal package it is possible
some downstreams use them, so add some wrappers but mark them as
deprecated.
