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)

Value Collection

GLib provides a set of macros for the varargs parsing support needed in variadic GObject functions such as [ctor@GObject.Object.new] or [method@GObject.Object.set]

They currently support the collection of integral types, floating point types and pointers.

Macros

G_VALUE_COLLECT_INIT(value, _value_type, var_args, flags, __error)

Collects a variable argument value from a va_list.

We have to implement the varargs collection as a macro, because on some systems va_list variables cannot be passed by reference.

Since: 2.24

G_VALUE_COLLECT_INIT2(value, g_vci_vtab, _value_type, var_args, flags, __error)

A variant of G_VALUE_COLLECT_INIT that provides the [struct@GObject.TypeValueTable] to the caller.

Since: 2.74

G_VALUE_COLLECT(value, var_args, flags, __error)

Collects a variable argument value from a va_list.

We have to implement the varargs collection as a macro, because on some systems va_list variables cannot be passed by reference.

Note: If you are creating the value argument just before calling this macro, you should use the G_VALUE_COLLECT_INIT variant and pass the uninitialized GValue. That variant is faster than G_VALUE_COLLECT.

G_VALUE_COLLECT_SKIP(_value_type, var_args)

Skip an argument of type _value_type from var_args.

G_VALUE_LCOPY(value, var_args, flags, __error)

Stores a values value into one or more argument locations from a va_list.

This is the inverse of G_VALUE_COLLECT().

G_VALUE_COLLECT_FORMAT_MAX_LENGTH

The maximal number of [type@GObject.TypeCValue]s which can be collected for a single GValue.
