18620: core: add core_mutex_debug to aid debugging deadlocks r=maribu a=maribu
### Contribution description
Adding `USEMODULE += core_mutex_debug` to your `Makefile` results in
on log messages such as
[mutex] waiting for thread 1 (pc = 0x800024d)
being added whenever `mutex_lock()` blocks. This makes tracing down
deadlocks easier.
### Testing procedure
Run e.g.
```sh
USEMODULE=core_mutex_debug BOARD=nucleo-f767zi make -C tests/mutex_cancel flash test
```
which should provide output such as
```
Welcome to pyterm!
Type '/exit' to exit.
READY
s
[mutex] waiting for thread 1 (pc = 0x8000f35)
START
main(): This is RIOT! (Version: 2022.10-devel-841-g5cc02-core/mutex/debug)
Test Application for mutex_cancel / mutex_lock_cancelable
=========================================================
Test without cancellation: OK
Test early cancellation: OK
Verify no side effects on subsequent calls: [mutex] waiting for thread 1 (pc = 0x800024d)
OK
Test late cancellation: [mutex] waiting for thread 1 (pc = 0x0)
OK
TEST PASSED
```
```sh
$ arm-none-eabi-addr2line -a 0x800024d -e tests/mutex_cancel/bin/nucleo-f767zi/tests_mutex_cancel.elf

19504: cpu/cc26xx_cc13xx: Fix bogus array-bound warning r=maribu a=maribu
### Contribution description
GCC 12 create a bogus array out of bounds warning as it assumes that because there is special handling for `uart == 0` and `uart == 1`, `uart` can indeed be `1`. There is an `assert(uart < UART_NUMOF)` above that would blow up prior to any out of bounds access.
In any case, optimizing out the special handling of `uart == 1` for when `UART_NUMOF == 1` likely improves the generated code and fixes the warning.

### Testing procedure
The actual change is a pretty obvious one-liner, so that code review and a green CI should be sufficient. If not, running any UART example app without regression should do.

19506: tools/openocd: Fix handling of OPENOCD_CMD_RESET_HALT r=maribu a=maribu
### Contribution description
The OPENOCD_CMD_RESET_HALT was not longer correctly passed to the script. This fixes the issue.
### Testing procedure
Flashing of e.g. the `cc2650-launchpad` with upstream OpenOCD should work again.
### Issues/PRs references
The change was added to https://github.com/RIOT-OS/RIOT/pull/19050 after testing the PR and before merging. I'm not sure if the fix never worked because of this, or if behavior of `target-export-variables` or GNU Make changed.

19485: sys/shell: Fix missing dependency r=aabadie a=maribu
### Contribution description
The shell commands depend on the shell module being use. This was already the case in KConfig, but was overlooked in the shell's `Makefile.dep`.
In addition, this uncovered that `tests/memarray` had a bogus dependency on shell commands without every using the shell.
### Testing procedure
Ideally binaries should not differ (except for debug section).

### Testing procedure
Use any GD32V board with a JTAG adapter and flash the bootloader:
```python
PROGRAMMER=openocd BOARD=sipeed-longan-nano make -C bootloaders/riotboot flash
```
Flash slot 0 and set `RIOT_VERSION` to 1
```python
USEMODULE=stdio_uart FEATURES_REQUIRED=riotboot RIOT_VERSION=1 \
PROGRAMMER=openocd BOARD=sipeed-longan-nano make -C tests/shell riotboot/flash-slot0
...
### Flashing Target ###

Flashing with IMAGE_OFFSET: 0x08001000
```
```python

test_shell.
```
Flash slot 1 and set `RIOT_VERSION` to 2
```python
USEMODULE=stdio_uart FEATURES_REQUIRED=riotboot RIOT_VERSION=2 \
PROGRAMMER=openocd BOARD=sipeed-longan-nano make -C tests/shell riotboot/flash-slot1
...
### Flashing Target ###

The shell_cmds module depends on the shell module. This was correctly
added to KConfig, but the Makefile dependencies missed this one. This
commit adds the missing dep.
To be able to reconfigure the PLL multiplier in clock configuration, the existing value has to be reset first. This becomes necessary when changing the core clock, e.g. when booting with riotboot an application that uses USB.
To allow CPU specific definitions in `cpu.h`, `riscv_common/cpu.h` is renamed to ``riscv_common/cpu_common.h` and included in new `cpu.h` files for FE310 and GD32V.
19450: cpu/esp32: fix compilation issues with GCC 12.2 r=benpicco a=gschorcht
### Contribution description
This PR provides the changes in `cpu/esp32` and `cpu/esp_common` to fix the compilation issues with GCC v12.2. It is required as the first step in the preparation of the upgrade to ESP-IDF version 5.1.
**Please note**: Insead of fixing the ESP-IDF 4.4 code itself by a big bunch of patches to fix the compilation problems with GCC v12.2, it temporarily disables some warnings. The reason is that the ESP-IDF 5.1 requires GCC v12.2 and should be fixed for this compiler version by the vendor.
### Testing procedure
Green CI
The change were already tested with all ESP-specific modules like `esp_now`, `esp_wifi`, `esp_spi` and `esp_ble` for all supported ESP platforms.

19476: native/syscalls: rename real_clock_gettime to clock_gettime r=benpicco a=Teufelchen1
### Contribution description
When compiling RIOT for native using a recent LLVM and enabling ASAN, one might encounter "Duplicated symbol".
This is due to a name clash with `real_clock_gettime()` in compiler-rt from [LLVM](f50246da65), I renamed RIOTs `real_clock_gettime` and just default to the posix function `clock_gettime`. The wrapper existed, most likely, for consistency only.
(The best solution would probably to convince the LLVM folks to declare their symbol as `static` and refactor a bit)
### Testing procedure
Passing CI should be enough.

after reviewing #19369 i found that there is a conversion to nanoseconds just to convert it to microseconds some instrunctions later for ztimer64_usec to handle it this removes one of the conversions (convert once direct to microseconds)

19447: boards/nucleo-f429zi: Provide 2nd timer r=benpicco a=maribu
### Contribution description
- Add a common timer config with two (instead of only one) timer using TIM2 + TIM5
- Mostly copy-pasting the cfg_timer_tim2.h and cfg_timer_tim5.h together
- Make use of that for the `nucleo-f429zi`
### Testing procedure
E.g. `tests/periph_timer`, but also grepping for TIM2 and TIM5 in `boards/nucleo-f429zi/include/periph_conf.h` to detect any conflict e.g. between PWM and timer config.
