cyclopentane 465f6a6284 cryptenroll,cryptsetup,shutdown: only call mlockall if we have CAP_IPC_LOCK 
Calling mlockall in an unprivileged process most notably had the effect
of making systemd-cryptenroll OOM while trying to open a normal-sized
argon2 keyslot due to it hitting RLIMIT_MEMLOCK.

Mike Yuan bbce82dfab core/unit: drop unneeded unit_modify_nft_set() call during coldplug 
We re-realize all unit cgroups upon daemon-reload, and
cgroup_context_apply() would take care of NFT set refreshing.
No need to duplicate that in unit_coldplug().

Yu Watanabe 112cbc3790 journal-file: do not trigger assertion on removed or corrupted journal file 
When a journal file is removed or corrupted, then the value `p`, which is
read from Object.data.entry_offset, may be zero.

Note, journal_file_move_to_object() checks the passed offset and return
-EBADMSG if it is invalid.

Fixes the issue reported at
https://github.com/systemd/systemd/pull/40372#issuecomment-3762907261.

Mike Yuan 12effc32da core/unit: several cleanups for unit_queue_job_check_and_collapse_type() 
* Rename to _mangle_type() - it turned out this one doesn't collapse
  anything, but rather mangles the type if reload_if_possible is set.
  Hence name accordingly.
* Use -ELIBEXEC rather than -EUNATCH to denote dependency only units.
* Add a comment about the JOB_STOP and load state check.

Lennart Poettering c67abc9c43 chase: extend coverage of the root fd shortcut

Lennart Poettering ded2531764 chase: optimize the special case where no root dir specified 
Now that we can recognize the root dir in chaseat() sanely, let's use it
top optimize the very common special case where we have no root dir to
consider, and directly call open_tree().

Lennart Poettering ee79c9d309 fd-util: introduce XAT_FDROOT fd shortcut for the root dir 
This takes inspiration from AT_FDCWD, but always references the root dir
rather than the cwd. This allows various convenience uses, as we can now
reference the root dir without actually allocating an fd for chaseat(),
fd_get_path() and various others.

The value of XAT_FDROOT is chosen so that it is not a valid fd (essential,
because we do not intend to hook this up everywhere, just where we need
it, just like AT_FCWD only works in some syscalls), and we want uses at
the wrong places to fail cleanly. It also uses a valud outside of the
range where we usually return negative errnos, i.e. < -ERRNO_MAX.

Lennart Poettering e09b5366e5 string-util: accept ":" when stripping ANSI color sequences 
Since 6eabe9f2ff we generate sequences
with ":", hence we better also know how to strip them.

(Without this patch we'd strip simple ANSI colors, but not RGB ones that
use ":" syntax).

(While we are at it, also drop a duplicate "0" in the list of valid
chars)

Lennart Poettering 24c315e911 ansi-color: convert one more ANSI sequence from ";" to ":" separators 
This is a follow-up for 6eabe9f2ff where
one sequence was forgotten.
