Because rpmsg_virtio_lite is a better name to inform user that the
rpmsg virtio (original name) is a lite implementation of rpmsg virtio.

When CONFIG_LIBC_ARCH_ATOMIC is defined, the atomic_fetch_x
interface conflicts with the atomic_fetch_x interface in libcxx.
Therefore, it has been changed to a inline function.

The fake audio driver aims to easily simulate the functions of audio driver through reading and writing files.
With it, you can conveniently customize and define various capture or playback audio drivers for debugging or automated testing.

The `struct sensor_gnss_satellite.cf` may be parsed from `GSV.signal_id`(e.g. NMEA 0183 v4.11) and `struct sensor_gnss_satellite.constellation`

This patch adds support for velocity measurement sensors.
I plan to use it as a generic velocity type to be used for
Renesas FS3000 (Air Velocity Flow).

The temporary mappings via addrenv_select() and addrenv_restore() simply
do not work from interrupt, so remove its usage and replace with kmap
which is safe.
This allows mapping pages from others than the running task. Obiously
this can only be done with proper preparations (the task in question
cannot exit before the mapping is released).
If the current platform does not require a large PATH_MAX size support and toolchain supports alloca(),
we could turn off this option to improve performance.

S32C1I instructions may target cached, cache-bypass,
and data RAM memory locations. S32C1I instructions
are not permitted to access memory addresses in data ROM,
instruction memory or the address region allocated to
the XLMI port. Attempts to direct the S32C1I at these
addresses will cause an exception.

Modify the kernel to use only atomic_xx and atomic64_xx interfaces,
avoiding the use of sizeof or typeof to determine the type of
atomic operations, thereby simplifying the kernel's atomic
interface operations.

right now it is only possible to change the delivered power on the fly
by
1. selecting PDO2 slot
2. write to POO2
3. renegotiate power delivery by sw reset command
reason:
Due to incomplete handling of spinlock_t in arch/spinlock.h,
it should not be used directly by external code.
Furthermore, because pthread.h and nuttx/spinlock.h have a circular
dependency, pthread.h cannot successfully include nuttx/spinlock.h.
Therefore, we have split spinlock_type.h from spinlock.h.

reason:
1 There is a similar PR, https://github.com/apache/nuttx/pull/14079,
2 Currently, no one is using recursive locks with write_lock_irqsave/read_lock_irqsave.
3 Nested spinlock is harmful, prone to abuse and leading to a decline in code quality and performance
4 Nested spinlock is also not available in Linux.
5 In our future plans, nested usage of enter_critical_section and spin_lock_irqsave will also be removed.

reason:
1: spin_lock_init and spin_initialize have similar functionalities.
2: spin_lock and spin_unlock should be called in matching pairs.
