libmount: Fix atime remount for new API
All atime settings are mutually exclusive, and the attr_set mask for
the mount_setattr() syscall cannot contain multiple MOUNT_ATTR_ atime
related options.
Unfortunately, during a remount, the list of options is composed of
both old and new options. In this case, libmount sets more atime
options to the mask. The correct behavior is to use the last atime
related option from the list.

The syscall numbers should not be hardcoded in the header file. If we
really need them, there is UL_CHECK_SYSCALL() to define the numbers
for different architectures. I doubt it's really necessary. Just
update your kernel header files to get the latest kernel updates ...

meson: Correctly require the Python.h header for the python dependency
The current solution to require the Python.h header works around a bug
in Meson that has been fixed for version 1.4.1 of Meson.
Refer to https://github.com/mesonbuild/meson/issues/12862.
This change uses an explicit check for the Python.h include.
This verifies the required header exists.
This check is only necessary prior to version 1.4.1 of Meson.

Only the python executable is required for tests.
Version 1.4.1 of Meson will require the Python.h for find_installation.
This will result in the tests requiring Python.h unnecessarily.

All the existing tests are also done with --fcntl in effect, and then
we add one more test, namely that a flock(2) lock can be be obtained
even while a fcntl(2) lock is held - not that anyone should ever need
that, but it does show that the lock types are completely independent.

get_ns_ino() returns three inode numbers. The code for the two of three,
inodes for PARENT and USERNS, is moved to the new functions.
So we can reuse the code in other places in lsns.

lsfd: include linux/fcntl.h
asm/-headers are implementation details and not meant to be included
directly. Instead use the linux/ header which will always include the
correct asm/-headers.
flock: add support for using fcntl() with open file description locks
Currently, there is no way for shell scripts to safely access
resources protected by POSIX locking (fcntl with the F_SETLK/F_SETLKW
commands). For example, the glibc function lckpwdf(), used to
protect access to the /etc/shadow database, works by taking a
F_SETLKW on /etc/.pwd.lock .
Due to the odd semantics of POSIX locking (e.g. released when any file
descriptor associated to the inode is closed), we cannot usefully
directly expose the POSIX F_SETLK/F_SETLKW commands. However, linux
3.15 introduced F_OFD_SETLK[W], with semantics wrt. ownership and
release better matching those of flock(2), and crucially they do
conflict with locks obtained via F_SETLK[W]. With this, a shell script
can do
exec 4> /etc/.pwd.lock
flock --fcntl 4
<access/modify /etc/shadow ...>
flock --fcntl --unlock 4 # or just exit
without conflicting with passwd(1) or other utilities that
access/modify /etc/shadow.
No single-letter shorthand is defined for the option, because this is
somewhat low-level and the user really needs to know what he is doing.
Also, this leaves the door open for teaching --fcntl to accept an
optional argument: "ofd", the default, and "posix", should anyone find
a use for flock(1) taking a F_SETLK[W] lock.
tests: (lsns::ioctl_ns) record stdout/stderr for debugging the case
When the test case runs successfully, we expect the case test prints
nothing to stderr. If something is printed to stderr, it helps us
debug lsns command and the test case.
