19294: sys/shell: don't include suit command by default r=benpicco a=benpicco
19295: gcoap: Finish the gcoap_get_resource_list_tl -> gcoap_get_resource_list renaming r=benpicco a=chrysn
### Contribution description
In #16688, an argument was added to the `gcoap_get_resource_list` function by creating a new function `gcoap_get_resource_list_tl` with a deprecation and roll-over plan.
This plan has not been acted on so far.
This PR shortens the original plan by just adding the argument to `gcoap_get_resource_list` and removing `gcoap_get_resource_list_tl` in a single go. The rationale for this deviation is that while it's a public API, its only two practical consumers are the (built-in) well-known/core implementation, and the (built-in) CoRE Resource Directory (cord) endpoint. Moreover, a further change to this API (switching over to `coap_block_slicer_t`) is expected to happen within this release cycle, which would take something like 4 total releases to get through otherwise, which is unrealistic for an API that there are no known external users of.
A second commit clean up ToDo items (in the changed function's documentation) that referred to a IETF draft that has long been abandoned by the CoRE WG.
### Testing procedure
Plain inspection and CI passing should suffice.
### AOB
There is a second analogous pair left over from #16688, `gcoap_req_send` / `gcoap_req_send_tl`. As that *is* expected to be used widely, I prefer not to mix these two concerns, and get the present one through without unnecessary hold-up.

This is an API change in the latter, which would typically now take an
extra argument GCOAP_SOCKET_TYPE_UNDEF.

19243: cpu/gd32v: add periph_gpio_ll and periph_gpio_ll_irq support r=benpicco a=gschorcht
### Contribution description
This PR provides the `periph_gpio_ll` and `periph_gpio_ll_irq` support for GD32VF103. Level triggered interrupts are emulated.
`periph_gpio_ll_irq` could be split off from this PR as a separate PR if necessary.
### Testing procedure
Use any GD32V board and connect PA0 -> PB0 and PA1 -> PB1 where PA is the output port and PB the input port. With these connections `tests/periph_gpio_ll` should work.
```
BOARD=sipeed-longan-nano make -j8 -C tests/periph_gpio_ll flash term
```
If necessary, change the input and output pins by setting the environment variables and connect the corresponding pins, for example for `seeedstudio-gd32` PA1 -> PB8 and PA8 -> PB9:
```
PIN_OUT_0=1 PIN_OUT_1=8 PIN_IN_0=8 PIN_IN_1=9 BOARD=seedstudio-gd32 make -j8 -C tests/periph_gpio_ll flash term
```

This implements the XOR based error-correction code described by
Jürgen Fitschen (@jue89) at the RIOT Summit.
A parity byte is generated for each 3 payload bytes, then the payload array
is transposed by interpreting it as a 2D matrix with height of 3.
This is to reduce the chance of consecutive bytes ending up in the same
packet.
This allows to recover one in 3 lost data packets (if parity packets are received).

When the `tests/periph_spi` program succeeds the output can be interpreted as an error happened.
This PR makes it clearer when it does succeed.
### Contribution description
In `tests/periph_spi`:
- Explicitely say that the init operation was successful
- Rephrase the note to avoid misinterpretations
### Testing procedure
Run the `tests/periph_spi` program.
There is not much to test, just to verify the output, should be like this:
```

This reverts commit 5447203921.
### Contribution description
Compiling `examples/gnrc_networking_mac` using `TOOLCHAIN=llvm` yields the following error:
```
RIOT/sys/pm_layered/pm.c:77:16: error: unknown attribute 'optimize' ignored [-Werror,-Wunknown-attributes]
__attribute__((optimize(3)))
```
As indicated, this is because the attribute `optimize` is GCC only and not present in LLVM.
Compare the manpages of [GCC](https://gcc.gnu.org/onlinedocs/gcc/Common-Function-Attributes.html) and [LLVM](https://clang.llvm.org/docs/AttributeReference.html).
### Testing procedure
Since this should only affect performance and not behavior, no special testing is needed. I am not aware of any tests in RIOT which could verify that assumption.
### Issues/PRs references

19057: fuzzing: Add uri_parser setup r=benpicco a=Teufelchen1
Hello!
### Contribution description
This PR is a replacement for PR #18802
In this contribution:
* The variable `AFL_FLAGS` is renamed to `FLAGS_FOR_AFL` because AFL is always complaining that `AFL_FLAGS` is not a valid env var for it. While this is not a bug nor an issue, I found it to be annoying.
* A generic input reader is added to simplify building a test harness
* The usage of this reader is demonstrated by adding a harness for fuzzing the uri_parser
(needs squashing after review)
### Testing procedure
Go to `fuzzing/uri_parser` and run `make all-asan` and `make fuzz` to get some action going.
Also mildly interesting: `./dist/tools/compile_test/compile_like_murdock.py -b native -a fuzzing/uri_parser`
### Issues/PRs references
The original PR #18802 is replaced because the generic input reader is present in both PRs but this PoC harness is much simpler.

17066: sys/irq: Add C++ wrapper using RAII r=maribu a=jenswet
### Contribution description
This adds a C++ wrapper around the `irq.h` API. The wrapper uses RAII to accomplish a convenient and bug resistent use.
A little background: I'm currently writing my master thesis on using C++ for embedded development, at the working group that `@maribu` is part of. For that I will try to add better C++ support to several parts of RIOT and then do some benchmarking and metrics to compare it with the C implementation. For example, I also plan to add a wrapper around i2c, a std::cout drop-in replacement and probably some more about networks or threads.
### Testing procedure
I've added a unit test to verify that the IRQ wrapper calls the original `irq` functions as expected. As C++ and wrapper testing isn't done much so far in this project, I've added two additional headers to ease testing:
1. #17076 - fake functions framework, already merged
2. As there is no framework for C++ unit tests yet, I've added something for this too. Unfortunately the existing frameworks like GoogleTest, CppUTest or CppUnit don't easily compile for embedded or are difficult to integrate in to the RIOT build process. That's why I wrote some (simple) helper functions and macros inspired by the above frameworks. That allows to create C++ tests based on a fixture class with set up and tear down methods. It also allows some simple assertions and is easily extendable for other use cases. It wraps some of the fff functionality too.
Both of this is obviously not required for the initial reason of this PR. But I'd like to provide unit tests for the features that I suggest to introduce where possible. So I'd appreciate some feedback on that too. If you'd prefer a PR without or different tests please let me know.
You can run the test `irq_cpp` locally or on the CI to test the implementation.
Please feel free to give feedback or suggest improvements!

19100: cpu/esp_common: allow configuration of UART0 r=benpicco a=gschorcht
### Contribution description
This PR
- fixes the issue for ESP32 SoCs that UART0 signals can't be routed to arbitrary GPIOs and
- allows the configuration of the UART device used by the bootloader.
The UART interface and its configuration used by the STDIO are defined in RIOT using the define `STDIO_UART_DEV` and the configuration of the corresponding UART device in `periph_conf.h`.
However, the bootloader compiled directly in ESP-IDF uses its own definitions `CONFIG_ESP_CONSOLE_UART_*` for the UART configuration. To be able to use a consistent UART configuration in RIOT and the bootloader, e.g. to see the output of the 2nd stage bootloader, these `CONFIG_ESP_CONSOLE_UART_*` can be defined via a set of KConfig variables in RIOT (not yet implemented in Kconfig):
- `CONSOLE_CONFIG_UART_NUM` defines the UART device to be used by the bootloader and by `STDIO_UART_DEV`
- `CONSOLE_CONFIG_UART_RX` and `CONSOLE_CONFIG_UART_TX` define the GPIOs to be used by the bootloader and should be the GPIOs as defined in `periph_conf.h` for the corresponding UART device.
### Testing procedure
Any ESP32 node should still work with `stdio_uart` and the default configuration. To test an alternative configuration, use
```
CFLAGS='-DUART1_TXD=5 -DUART1_RXD=4 -DCONFIG_CONSOLE_UART_NUM=1 -DCONFIG_CONSOLE_UART_TX=5 -DCONFIG_CONSOLE_UART_RX=4' USEMODULE=esp_log_startup BOARD=esp32-wroom-32 make -C tests/shell flash
```
The bootloader output and the STDIO should be routed to UART1 at GPIO4 and GPIO5.

Having to cast a password provided as `const char *` to
`const uint8_t *` is a needless pain in the ass when using the API.
Hence, fix it by accepting passwords and salts as `const void *`
instead.
The previous implementation used creative construct for impedance
mismatching between the core list API (which returns a ptr to the
removed element if found) and the GNRC pkt list API (which returns a
ptr to the new list head) that creates a temporary list head on the
stack.
I'm not entirely sure if the previous implementation is containing
undefined behavior that is used against us with GCC >= 12.x, or if this
is a compiler bug. In either case, not reusing the core list API here
and just having a textbook linked list delete function here is not much
less readable and fixes the issue for our users.
This eliminates race conditions around unregistering netdevs.
gnrc_netreg_lookup-style functions perform a DEVELHELP check on whether
that lock is held.
Add USE_MODULE += "stdio_uart_onlcr" to enable it.
This is named after the "onlcr" stty flag, which does the same thing.

This header-only module provides a `string_utils.h` that currently
only provides the non-standard function `explicit_bzero()` to securely
wipe memory. It may be extended with other utility functions in the
future.
`tiny_strerror()` is a drop-in replacement for `strerror()`, but
instead of a long help message it returns the much shorter macro name
matching the given number.
The (pseudo-)module `tiny_strerror_as_strerror` can be used to
replace all calls to `strerror()` with calls to `tiny_strerror()`.
This adds support for netdevs implementing the new API that provides
`netdev_driver_t::confirm_send()`. This allows implementing netdevs
in an event based non-blocking fashion, making live of driver
developers a bit easier. In addition, `gnrc_tx_sync` will now throttle
users of `sock_udp_send()` so that they can only send datagrams as
fast as the network stack and hardware is able to send out.
Finally, this lays the groundwork to fetch TX statistics (such as
TX timestamps, reception of layer 2 ACKs/NACKs, etc.) from the network
devices.
