19513: boards/nrf52840dongle/doc: Update nrfutil pointers r=benpicco a=chrysn
### Contribution description
Nordic changed its nrfutil; this change adjust to it.
I'm not fully happy with recommending that tool at all due to its bad quality (see rambling in https://github.com/RIOT-OS/RIOT/issues/19511), but short of soldering on a debug header or touch-probing it with wires it's the only way in to the device. I may later add follow-up recommendations to switch to riotboot, but this now at least fixes the immediate issue.
### Testing procedure
* Look at the updated documentation.

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)

main(): This is RIOT! (Version: 2022.10-devel-841-g5cc02-core/mutex/debug)

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.

18763: sys/tiny_strerror: add missing error codes r=benpicco a=maribu
### Contribution description
When double-checking the error codes provided by newlib by default (without magic defines, such as `__LINUX_ERRNO_EXTENSIONS__` or `__CYGWIN__`), some where still missing in `tiny_strerror()`. This adds the missing ones.
This in turn showed that three errno codes were missing in the avr-libc compat `errno.h`, which are added as well.
### Testing procedure
Murdock should double check that the added errno codes indeed are defined by default.
### Issues/PRs references
