8da6413860 mountpoint-util: add public helper for comparing file handles 
We already have the code, let's move it to a function of its own and
export it.

a89690f719 mountpoint-util: make is_name_to_handle_at_fatal_error() an exported API 
And while we are at it, make it use ERRNO_IS_xyz() where appropriate.

And move it up a bit, so we can use in the whole of mountpoint-util.c
(which we want to later).

afb1fe36b8 introduce hashmap_ensure_replace() 
Similar to hashmap_ensure_put(), but replace existing items in the map,
as hashmap_replace().

36e48f22af mountpoint-util: do not assume symlinks are not mountpoints 
They very much can be with the new mount API.

016e9d8d08 core/exec-invoke: use sched_setattr instead of sched_setscheduler 
The kernel's sched_setattr interface allows for more control over a processes
scheduling attributes as the previously used sched_setscheduler interface.

Using sched_setattr is also the prerequisite for support of utilization
clamping (UCLAMP [1], see #26705) and allows to set sched_runtime. The latter,
sched_runtime, will probably become a relevant scheduling parameter of the
EEVDF scheduler [2, 3], and therefore will not only apply to processes
scheduled via SCHED_DEADLINE, but also for processes scheduled via
SCHED_OTHER/SCHED_BATCH (i.e., most processes).

ba694646ea iovec-util: make "struct iovec" and some helpers also available in EFI mode 
The construct is a POSIX invention, but it's just so useful, let's also
define it in EFI mode, so that we can use similar constructs in EFI mode
and userspace.

0cced2948f basic/linux: update kernel headers from v6.10-rc3 
This also
- merges basic/linux and shared/linux,
- moves BPF_JUMP_A() to basic/missing_bpf.h,
- copies from usrspace kernel headers directory generated by 'make headers',
  rather than copying from kernel tree,
- copies const.h into our tree to reduce change in ethtool.h,
- copies auto_fs.h into our tree to reduce change in auto_dev-ioctl.h.

uniquifying can be faster.

15930d5d9f pidref: record pidfd inode number in PidRef struct 
Besides internal comparisons, the inode number of pidfds
might be interesting directly to users, too. In the future
this field should also be exposed, so that it can serve as
a unique identifier of a process (but only for display,
as there's no method to map this back to a pid or pidfd).
