17086: usbdev: Add dedicated stall functions r=benpicco a=bergzand
### Contribution description
This PR adds dedicated stall functions for usbdev peripherals. Two
functions are added. The first function (usbdev_ep_stall) to enable and
disable the stall condition on generic endpoints. The second function is
a dedicated function to set the stall condition on endpoint zero in both
directions. This status can only be set and should automatically be
cleared by the usbdev implementation (or hardware) after a new setup
request is received from the host.
### Testing procedure
- examples/usbus_minimal should still enumerate correctly on the host side.
- #17085 can be used to demonstrate the ep0_stall function with the `tests/usbus_cdc_acm_stdio/` test

18392: drivers/servo: reimplement with high level interface r=benpicco a=maribu
### Contribution description
The previous servo driver didn't provide any benefit over using PWM directly, as users controlled the servo in terms of PWM duty cycles. This changes the interface to provide a high level interface that abstracts the gory PWM details.
In addition, a SAUL layer and auto-initialization is provided.
### Testing procedure
The test application provides access to the servo driver via the `saul` shell command.

```
should work

The function `read_page` was missing which lead to (from a user perspective) undefined behavior on the MTD layer.
### Testing procedure
Any application using MTD in conjunction with a board with an at24cxxx.
19271: core/xfa: disable asan on llvm r=benpicco a=Teufelchen1
### Contribution description
Hi! 🦎
When using llvm and address sanitation, the XFA trip the sanitizer.
This PR attempts to fix this by adding the `no_sanitize` attribute to the XFA macros. Sadly, this attribute is not known by gnu, a guard is hence needed. I'm open for alternatives as I dislike this solution but it is the best I could come up with.
### Testing procedure
Before this patch:
Go to `examples/gnrc_minimal` and run `TOOLCHAIN=llvm make all-asan` and then `make term`.
You should see an error similar to this:
```
==3374719==ERROR: AddressSanitizer: global-buffer-overflow on address 0x080774e0 at pc 0x0804af5e bp 0x0808eb88 sp 0x0808eb78

```
After applying this PR, the example can be build and run with llvm or gcc, with or without asan.

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

18903: pkg/tinyusb: add tinyUSB netdev driver r=dylad a=gschorcht
### Contribution description
This PR adds the tinyUSB netdev driver.
The tinyUSB netdev driver is part of the tinyUSB package and is enabled by module `tinyusb_netdev`. It is available for boards that provide the `tinyusb_device` feature.
**Please note** Since the tinyUSB package is distinct from (and incompatible with) the USB stack provided around USBUS in RIOT (see USB), the tinyUSB netdev driver cannot be used together with with any USBUS device class.
The tinyUSB netdev driver uses Ethernet over USB and supports the following protocols:
- CDC ECM (Ethernet Control Model)
- CDC NCM (Network Control Model)
- RNDIS (Microsoft Remote NDIS)
While Linux and macOS support all these protocols, Microsoft Windows only supports the RNDIS protocol and since Windows version 11 also the CDC NCM protocol. macOS supports the RNDIS protocol since version 10.15 (Catalina).
Which protocol is used is selected by the corresponding pseudomodules `tinyusb_class_net_cdc_ecm`, `tinyusb_class_net_cdc_ncm` and `tinyusb_class_net_rndis`.
The CDC ECM protocol (`tinyusb_class_net_cdc_ecm`) and the RNDIS protocol (`tinyusb_class_net_rndis`) can be used simultaneously to support all operating systems, for example :
```
USEMODULE='tinyusb_netdev tinyusb_class_net_rndis tinyusb_class_net_cdc_ecm' \
BOARD=... make -C ... flash
```
In this case, the CDC ECM protocol is the default protocol and the RNDIS protocol the alternative protocol defined as second device configuration. The CDC NCM protocol cannot be used together with the CDC ECM or the RNDIS protocol.
This PR includes PR #18983 for now to be compilable.
Comparison with USBUS CDC ECM (`nucleo-f767zi` board):
```

65916 596 18728 85240 14cf8 tests_pkg_tinyusb_netdev.elf
```
```
text data bss dec hex filename
63120 544 15444 79108 13504 tests_usbus_cdc_ecm.elf
```
### Testing procedure
Use a board that is supported by tinyUSB. Compile and flash the test application for each protocol:
1. RNDIS
```
BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash
```
2. CDC ECM
```
CLASS=tinyusb_class_net_cdc_ecm BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash
```
3. CDC NCM
```
CLASS=tinyusb_class_net_cdc_ncm BOARD=... make -j8 -C tests/pkg_tinyusb_netdev flash
```
For each test, a network interface should be added on the host. Use command `ifconfig` on USB device and on the host and check that both have a link local address. In syslog there should be an output like the following:

17810: drivers/slipdev: implement sleep states r=benpicco a=benpicco
18348: sys/net/gnrc/pktbuf_static: make use of alignas() r=maribu a=maribu
### Contribution description
Since we are now using C11, we can make use of `alignas()` provided by `<stdalign.h>` to make the alignment code easier to read.
### Testing procedure
I didn't expect this to change binaries, but is safes 4 bytes. `elf_diff` shows that the compiler (at least GCC 11.3.0) was not able to detect that `gnrc_pktbuf_static_buf` was just an alias for `_pktbuf_buf`. That makes sense since it would be hard without LTO to rule out external writes to `gnrc_pktbuf_static_buf`, unless one would have added a `const` (to the pointer, not to the data the pointer points to).
The [output of `elf_diff`](https://mari-bu.de/pr_18348_gnrc_pktbuf_static_elf_diff.html) looks otherwise quite unscary.
Also:

19048: drivers/sht2x: some small improvements r=benpicco a=gschorcht
### Contribution description
This PR provides the following improvements for the SHT2x driver:
- migration to `ztimer` 8a605517f5 and 367549940de3bd8910052334c34af028d4992741
- floating point arithmetics replaced by integer arithmetics f424caebbfec9f2be56aa2337c6cc09dba5b97d6
- fix of sleep times (typical times replaced by maximum times as recommended by the datasheet) 13615c72094b8541ee62c3e8ed5a36dc4d725fd0
- release of the I2C bus during sleep 9415c216cfab734520ef98dd00b350c22f342c60
- Kconfig configuration of sensor parameters added dadbbcb4c328350893db53ba6743d03cb34ecc1c
- no-hold mode is now the default mode instead of the hold mode
Regarding the sleep times: The typical measurement times were used as sleep times. According to the datasheet, typical measurements are only recommended for calculating energy consumption, while maximum values should be used for calculating waiting times in communication. Therefore, the typical time values were replaced by maximum time values for the sleep in no-hold mode.
Regarding the hold mode: In hold mode, the sensor uses clock stretching until the measurement results can be read by the MCU. This blocks both the I2C bus and the MCU during the entire measurement, which can take up to 85 ms if I2C is not interrupt-driven. Therefore, the no-hold mode is now used by default, where the calling thread sleeps during the measurement, but the MCU is not completely blocked. Furthermore, the hold mode requires that the MCU supports clock stretching. Even if the MCU supports clock stretching, the hold mode with clock stretching doesn't seem to work with different MCUs. I couldn't get it working for STM32 and ESP32.
Regarding the I2C bus during sleep: If the no-hold mode is used and the calling thread sleeps up to 85 ms, it makes sense to release the I2C bus until the measurement results are available.
### Testing procedure
`tests/driver_sht2x` should still work.
