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.

19106: core/lib: Add macros/utils.h header r=aabadie a=maribu
### Contribution description
The macros CONCAT(), MIN(), and MAX() are defined over and over again in RIOT's code base. This de-duplicates the code by moving the macros to a common place.
### Testing procedure
Generated binaries don't change, as this only a de-duplication of macros that doesn't change their definition.

This commits add documentation to the HDC1000 params and adds generic
exclude patters to the doc check, so that when boards provide custom
HDC1000 params they do not need to document them again. The reasoning
is that the documentation in the central place is sufficient.
This commits add documentation to the FXOS8700 params and adds generic
exclude patters to the doc check, so that when boards provide custom
FXOS8700 params they do not need to document them again. The reasoning
is that the documentation in the central place is sufficient.
In addition, a generic exclude patter is added to match FXOS8700_REG_*,
as the register names are relatively self-explaining and an
implementation detail of the driver that doesn't need public
documentation.
This commits add documentation to the AT86RF2xx params and adds generic

18756: drivers/usbdev_synopsys_dwc2: add EFM32 support r=chrysn a=gschorcht
### Contribution description
This PR provides the changes for the Synopsys USB OTG IP core DWC2 driver for EFM32 MCUs. It also provides the changes of the board definition for `stk3600` and `stk3700` for testing.
### Testing procedure
`tests/usbus_hid` should work on the EFM32 boards `stk3600` (EFM32LG family) and `stk3700` (EFM32GG family).
It is already tested for a `sltb009a` board (EFM32GG12 family).

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.

According to the data sheet, typical times are recommended for calculating energy consumption, while maximum values should be used for calculating waiting times in communication. Therefore, the typical time values are replaced by maximum time values for sleep.
The code did not take into account that valid bus numbers are
0...(COUNT-1).
This patch corrects this. It also makes use of the newly introduced
SOFT_SPI_NUMOF define.
