Allow CPUSchedulingPolicy to be set to "ext". SCHED_EXT is a new
scheduling policy in Linux v6.12 that allows processes to be scheduled
using custom BPF schedulers instead of the default in-kernel ones.
Selectively setting the SCHED_EXT policy is useful for systems running
in "partial mode" where not all processes are run using a custom
scheduler.
Fallback to SCHED_OTHER and print an error message for systems where
SCHED_EXT isn't available.
musl's getopt_long() behaves something different in handling optional arguments:
```
$ journalctl _PID=1 _COMM=systemd --since 19:19:01 -n all --follow
Failed to add match 'all': Invalid argument
```
This introduces getopt_long_fix() that reorders the passed arguments to make
getopt_long() provided by musl works as what we expect.
Also, musl's getopt() always behaves POSIXLY_CORRECT mode, and stops parsing
arguments when a non-option string found. Let's always use getopt_long().
This reverts commit 3ae7d8fd87.
Now utmp support is always disabled when building with musl,
and all definitions are unused in that case. Let's remove it.
musl neither support GLOB_ALTDIRFUNC nor GLOB_BRACE.
Let's make safe_glob() work even when GLOB_ALTDIRFUNC is not supported.
Currently, GLOB_BRACE is simply ignored when it is not supported.
musl provides XSI compliant strerror_r(), and it is slightly different
from the one by glibc.
Let's introduce a tiny wrapper to convert XSI strerror_r() to GNU one.
The wrapper also patches musl's spurious catchall error message.
glibc's sys/stat.h includes linux/stat.h, and we have copy of it from
the latest kernel, hence all new flags are always defined.
However, musl's sys/stat.h does not include linux/stat.h, and moreover,
they conflict with each other, hence we cannot include both header
simultaneously. Let's define missing macros to support musl.
This is to avoid build failures like below for musl.

Even 'gshadow' meson option is disabled, src/shared/userdb.c and
src/shared/user-record-nss.c include gshadow.h unconditionally.
Let's introduce dummy header to make them compiled gracefully.
Those were added before 0.61 which is our minimum version.
Dots were dropped from the end of some messages. Most messages did not have the
trailing dot.
0.63 added support for multi-line f-strings. We can't use those yet.
We went back and forth between 'prog.sh', files('prog.sh'), and
find_program('prog.sh'). We want to use files() or find_program() so that we
get a good error message if the file is missing. Behaviour of meson changed
over time, and in the past not all forms could be used in all places. For
example 0f4c4f3824 added find_program() in many
places to avoid repeated messages. But it seems that all recent meson versions
work fine with files().
find_program prints silly messages:
Program tools/make-man-index.py found: YES
(/home/zbyszek/src/systemd/tools/make-man-index.py)
Program tools/meson-render-jinja2.py found: YES
(/home/zbyszek/src/systemd/tools/meson-render-jinja2.py)
...
We know that those files will be found, they are part of the git checkout.
With files() this is gone and the meson output is easier to read.
All those files are standalone programs that can be executed directly.
Some .py files were marked executable, others weren't, probably accidentally.
Mark them all as executable in preparation for subsequent changes.
The header provides _MIPS_SIM_ABI32 and friends. Glibc indirectly includes
the header through sys/syscall.h or unistd.h, but let's explicitly include
the header where we use _MIPS_SIM_ABI32 and friends.
Then, move syscall definitions to the wrapper, and prototypes are moved
to relevant headers.
This also adds checks for add_key() and request_key(), as one day
glibc may be going to add some of them separatedly.
The check for fspick in meson.build is dropped, as it is currently
unused in our code.
This also moves
- basic/missing_bpf.h -> include/override/linux/bpf.h,
- basic/missing_keyctl.h -> include/override/linux/keyctl.h.
This also moves syscall tables and generators to the same directory.
Note, inclusion of asm/sgidefs.h is dropped, as it is already included
by unistd.h and sys/syscall.h.
- pass our system include directories to make generators use our libc
wrappers and latest kernel headers,
- include relevant headers in generated gperf file,
- use files() rather than find_program(), as the result of
find_program() cannot be passed to 'input' of custom_target(),
- move generate-bpf-delegate-configs.py to src/core/, as it is only used
by libcore.
