vasilito cee25393d8 fix: boot process improvements — dependency cycle, INIT_NOTIFY, probing loop, and log spam fixes 
- Fix P15-8-init-cycle-detection.patch: replace visiting+error with seen+silent-skip
  to eliminate 11 false-positive 'dependency cycle detected' errors on shared deps
- Fix P0-daemon-fix-init-notify-unwrap.patch: remove eprintln! for missing
  INIT_NOTIFY (expected for oneshot_async services, ~7 daemons affected)
- Fix driver-manager hotplug loop: add PERMANENTLY_SKIPPED static set shared
  between hotplug handler and DriverConfig::probe() to stop infinite re-probing
  of Fatal/NotSupported/deferred-exhausted device+driver pairs (e.g. ided)
- Fix driver-manager log_timeline: suppress repeated EPIPE/ENOENT errors with
  AtomicI32 dedup and AtomicBool one-shot guards for boot timeline JSON
- Add driver-manager SIGTERM handler, ACPI bus registration, --status mode,
  driver reap loop, graceful shutdown, and reduced deferred retries (30→3)

Suppress extern inline with HP-UX cc, as it appears to be broken; see
<https://lists.gnu.org/r/bug-texinfo/2013-02/msg00030.html>.
Suppress extern inline with Sun C in standards-conformance mode, as it
mishandles inline functions that call each other. E.g., for 'inline void f
(void) { } inline void g (void) { f (); }', c99 incorrectly complains
'reference to static identifier "f" in extern inline function'.
This bug was observed with Oracle Developer Studio 12.6
(Sun C 5.15 SunOS_sparc 2017/05/30).
Suppress extern inline (with or without __attribute__ ((__gnu_inline__)))
on configurations that mistakenly use 'static inline' to implement
functions or macros in standard C headers like <ctype.h>. For example,
if isdigit is mistakenly implemented via a static inline function,
a program containing an extern inline function that calls isdigit
may not work since C99 through C23 prohibit extern inline functions
from calling static functions (ISO C 23 § 6.7.5 ¶ 3)).
Although a future C standard will likely relax this restriction
<https://www.open-std.org/jtc1/sc22/wg14/www/docs/n3622.txt>,
respect it for now. This bug is known to occur on:
OS X 10.8 and earlier; see:
https://lists.gnu.org/r/bug-gnulib/2012-12/msg00023.html
DragonFly; see
http://muscles.dragonflybsd.org/bulk/clang-master-potential/20141111_102002/logs/ah-tty-0.3.12.log
FreeBSD; see:
https://lists.gnu.org/r/bug-gnulib/2014-07/msg00104.html
OS X 10.9 has a macro __header_inline indicating the bug is fixed for C and
for clang but remains for g++; see <https://trac.macports.org/ticket/41033>.
Assume DragonFly and FreeBSD will be similar.
GCC 4.3 and above with -std=c99 or -std=gnu99 implements ISO C99
inline semantics, unless -fgnu89-inline is used. It defines a macro
__GNUC_STDC_INLINE__ to indicate this situation or a macro
__GNUC_GNU_INLINE__ to indicate the opposite situation.
GCC 4.2 with -std=c99 or -std=gnu99 implements the GNU C inline
semantics but warns, unless -fgnu89-inline is used:
warning: C99 inline functions are not supported; using GNU89
warning: to disable this warning use -fgnu89-inline or the gnu_inline function attribute
It defines a macro __GNUC_GNU_INLINE__ to indicate this situation.

So, if we insist on using the 'extern' keyword ('extern CC' idiom):
* If _GL_ATTRIBUTE_* expands to bracket syntax [[...]]
in both C and C++, there is one available position:
- between the function name and the parameter list.
* If _GL_ATTRIBUTE_* expands to __attribute__((...)) syntax
in both C and C++, there are several available positions:
- before the return type,
- between return type and function name,
- at the end of the declaration.
* If _GL_ATTRIBUTE_* expands to bracket syntax [[...]] in C and to
__attribute__((...)) syntax in C++, there is no available position:
it would need to come before 'extern' in C but after 'extern "C"'
in C++.
* If _GL_ATTRIBUTE_* expands to __attribute__((...)) syntax in C and
to bracket syntax [[...]] in C++, there is one available position:
- before the return type.
Whereas, if we use the 'EXTERN_C_FUNC' idiom, which conditionally
omits the 'extern' keyword:
* If _GL_ATTRIBUTE_* expands to bracket syntax [[...]]
in both C and C++, there are two available positions:
- before the return type,
- between the function name and the parameter list.
* If _GL_ATTRIBUTE_* expands to __attribute__((...)) syntax
in both C and C++, there are several available positions:
- before the return type,
- between return type and function name,
- at the end of the declaration.
* If _GL_ATTRIBUTE_* expands to bracket syntax [[...]] in C and to
__attribute__((...)) syntax in C++, there is one available position:
- before the return type.
* If _GL_ATTRIBUTE_* expands to __attribute__((...)) syntax in C and
to bracket syntax [[...]] in C++, there is one available position:
- before the return type.
The best choice is therefore to use the 'EXTERN_C_FUNC' idiom and
put the attributes before the return type. This works regardless
to what the _GL_ATTRIBUTE_* macros expand.

that is intended to inspect a variable set from within a signal handler
while (!signal_occurred)

dnl On OpenBSD >= 6.2, the locale_t type and the uselocale(), newlocale(),
dnl duplocale(), freelocale() functions exist but are effectively useless,
dnl because the locale_t value depends only on the LC_CTYPE category of the
dnl locale and furthermore contains only one bit of information (it
dnl distinguishes the "C" locale from the *.UTF-8 locales). See
dnl <https://cvsweb.openbsd.org/src/lib/libc/locale/newlocale.c?rev=1.1&content-type=text/x-cvsweb-markup>.
dnl In the setlocale() implementation they have thought about the programs
dnl that use the API ("Even though only LC_CTYPE has any effect in the
dnl OpenBSD base system, store complete information about the global locale,
dnl such that third-party software can access it"), but for uselocale()
dnl they did not think about the programs.
dnl In this situation, even the HAVE_NAMELESS_LOCALES support cannot make
dnl uselocale() work.
dnl Similarly on Android. See
dnl <https://android.googlesource.com/platform/bionic/+/refs/heads/main/libc/bionic/locale.cpp>.
dnl So, define HAVE_FAKE_LOCALES and disable all per-thread locale support.

/* alignof (TYPE), also known as _Alignof (TYPE), yields the alignment
requirement of a structure member (i.e., slot or field) that is of
type TYPE, as an integer constant expression.
This differs from GCC's and clang's __alignof__ operator, which can
yield a better-performing alignment for an object of that type. For
example, on x86 with GCC and on Linux/x86 with clang,
__alignof__ (double) and __alignof__ (long long) are 8, whereas
alignof (double) and alignof (long long) are 4 unless the option
'-malign-double' is used.
The result cannot be used as a value for an 'enum' constant, if you
want to be portable to HP-UX 10.20 cc and AIX 3.2.5 xlc. */
/* GCC releases before GCC 4.9 had a bug in _Alignof. See GCC bug 52023

to the alignment A, where A is an integer constant expression. For
example:
int alignas (8) foo;

aligns the address of FOO and the offset of BAR to be multiples of 8.
A should be a power of two that is at least the type's alignment
and at most the implementation's alignment limit. This limit is
2**28 on typical GNUish hosts, and 2**13 on MSVC. To be portable
to MSVC through at least version 10.0, A should be an integer
constant, as MSVC does not support expressions such as 1 << 3.
To be portable to Sun C 5.11, do not align auto variables to
anything stricter than their default alignment.
The following C23 requirements are not supported here:
- If A is zero, alignas has no effect.
- alignas can be used multiple times; the strictest one wins.
- alignas (TYPE) is equivalent to alignas (alignof (TYPE)).
