* Make readv/writev implementations update struct uio
This can simplify partial result handling.
* change the error number on the overflow from EOVERFLOW to EINVAL
to match NetBSD
* add a commented out uio_offset field. I used "#if 0" here as
C comments can't nest.
* add a few helper functions
Note on uio_copyfrom/uio_copyto:
although i'm not quite happy with the "offset" functionality,
it's necessary to simplify the adaptation of some drivers like
drivers/serial/serial.c, which (ab)uses the user-supplied buffer
as a line-buffer.
Add support for watchdog timer notifer chain so that users
can customize the callback function when the watchdog timer
times out which enabled by Auto-monitor

This commit cleans up redundant header file includes throughout the codebase.
The changes include:
- Removing duplicate #include directives that were present in the same file
- Consolidating includes that were split across multiple lines unnecessarily
- Removing unused includes that were no longer needed
- Fixing some formatting issues with includes
The changes improve code organization and maintainability by:
- Reducing unnecessary dependencies
- Making include dependencies more explicit
- Following consistent include patterns
- Removing dead code
No functional changes are made - this is purely a code cleanup commit.

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).
