The constants BIG_ENDIAN etc. were not consistently defined. This
bug was not caught by the unit tests, as the preprocessor would
treat undefined macros as being `0` in numeric comparisons, hence
the following test did select the correct implementation:
```C
#if BYTE_ORDER == LITTLE_ENDIAN
/* correct implementation for all currently supported boards */
#endif
```
This adds now an explicit test to the unit tests to ensure that the
magic numbers are consistently the correct values. Hence, this bug
should no longer be able to sneak in.

Reverts the type changes for the array size variables, as `size_t` is needed
in the function calls `fib_get_next_hop` and `fib_get_destination_set`.
Fixes 475a55136a
The CC2538-CC2592-DK is one of the few readily available and
affordable boards featuring a legacy CC2538 MCU. This should make
maintaining RIOT support for that legacy MCU more affordable :-)
- Added helper function to avoid 'format-truncation' warning
- Changed all `size_t` types to `unsigned`
- Changed function names from `_FIB_` to `_fib_`
This adds test coverage for removing ztimers with focus on ensuring that
offsets are correctly updated on subsequent timers (e.g. not having
timers fire too early).
19487: nanocoap: implement extended tokens (RFC 8974) r=benpicco a=benpicco
19808: boards: add ESP32-S3-USB-OTG support r=benpicco a=gschorcht
### Contribution description
This PR provides the support for the [ESP32-S3-USB-OTG](https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32s3/esp32-s3-usb-otg/user_guide.html) board.
The SD card can only be used in SPI mode at the moment. As soon as PR #19786 is merged, the SD/MMC support can be enabled and the SD card can then be used in SD mode with 4-bit data bus width.
The display uses uses the ST7789 driver IC that is compatible with the ST7735. For that purpose the ST7735 driver is extended by a pseudomodule definition `st7789` for the ST7789 which is enabled by the board and enables automatically the `st7789` (e57c48a33ee2a869c15603788e5306ba066f91cf). Vise versa, board's `Makefile.dep` enables automatically the `st7789` pseudomodule if the `st7735` is used. The pseudomodule `st7789` is just used to increase the upper limit for supported lines. This change is also part of PR #19807.
~The PR includes a very small documentation fix for ESP32-S3-DevKit board that was noticed during the development of this board definition (1155b6ac1b8efa39d8a0bd7150e602095159fdc1).~
### Testing procedure
The board has been tested with all basic tests for supported hardware including `tests/driver/st3375`:

19706: boards/olimex-msp430-h2618: add new board r=maribu a=maribu
### Contribution description
This adds support of the Olimex MSP430-H2618 board. This board has plenty of RAM and ROM for an MSP430 board (even more than the z1), but still is easily obtainable.
