debug.h is a NuttX-specific, non-POSIX header. Placing it in the
top-level include/ directory creates naming conflicts with external
projects that define their own debug.h.
This commit moves the canonical header to include/nuttx/debug.h,
following the NuttX convention for non-POSIX/non-standard headers,
and updates all in-tree references.
A backward-compatibility shim is left at include/debug.h that
emits a deprecation #warning and re-includes <nuttx/debug.h>,
allowing out-of-tree code to continue building while migrating.

Move mutex lock before checking flist to prevent race condition where
events could be lost when occurring simultaneously with service opening.

Nuttx currently has 2 types of sleep interfaces:
1. Signal-scheduled sleep: nxsig_sleep() / nxsig_usleep() / nxsig_nanosleep()
Weaknesses:
a. Signal-dependent: The signal-scheduled sleep method is bound to the signal framework, while some driver sleep operations do not depend on signals.
b. Timespec conversion: Signal-scheduled sleep involves timespec conversion, which has a significant impact on performance.
2. Busy sleep: up_mdelay() / up_udelay()
Weaknesses:
a. Does not actively trigger scheduling, occupy the CPU loading.
3. New interfaces: Scheduled sleep: nxsched_sleep() / nxsched_usleep() / nxsched_msleep() / nxsched_ticksleep()
Strengths:
a. Does not depend on the signal framework.
b. Tick-based, without additional computational overhead.
Currently, the Nuttx driver framework extensively uses nxsig_* interfaces. However, the driver does not need to rely on signals or timespec conversion.
Therefore, a new set of APIs is added to reduce dependencies on other modules.
(This PR also aims to make signals optional, further reducing the code size of Nuttx.)

Most tools used for compliance and SBOM generation use SPDX identifiers
This change brings us a step closer to an easy SBOM generation.

This patch fixed userspace headers conflict. Architecture-related definition and API should not be exposed to users.

all os-api those have post/wait feature will not allowed in pm_callbacks
and pm_handler, until we support by cpu/tcb sched_lock and add
sched_lock/unlock back here. Then should revert this commit.

If sched lock before irq save, and irq handler do post, scheduler will
be delayed after WFI until next sched unlock. which is not acceptable.

pm process should be done by chip specific, but we can provide a standard

critical_section is not compatible with irq disabled, have to delay the

as we always want to take critical_section, and it is not long time job,
take mutex is not necessary, use spinlock_irq_save as a replace is
better, dont't have to take global critial_section in pm.

After change, when CONFIG_PM_NDOMAINS > 1,
the pm_register will not able to get notificaion
from not PM_IDLE_DOMAIN.
Should use pm_domain_register as a replacement.
Isolate domains from global callbacks can decrease
not necessary execution, and reduce the
lock instruction requirements.

only when first time change state can hold WFI for enough time thresh,
allow second time goto target state,
suitable for the case when wakeup from sleep too slow, etc.
