The evtimer_msg test is expanded to also delete entries. Furthermore the messages that are printed should now show numbers that are very close (if not equal). Something like this: At 740 ms received msg 0: "#2 supposed to be 740" At 1081 ms received msg 1: "#0 supposed to be 1081" At 1581 ms received msg 2: "#1 supposed to be 1581" At 4035 ms received msg 3: "#3 supposed to be 4035" The function evtimer_print is also called to show the intermediate status of evtimer entries.

The test randomly fails on `native` due to timers being not accurate but
it cannot be otherwise. So better disable it than raising fake errors.
main(): This is RIOT! (Version: buildtest)
Testing generic evtimer
This should list 2 items
ev #1 offset=1000
ev #2 offset=500
This should list 4 items
ev #1 offset=659
ev #2 offset=341
ev #3 offset=500
ev #4 offset=2454
Are the reception times of all 4 msgs close to the supposed values?
At 662 ms received msg 0: "#2 supposed to be 659"
At 1009 ms received msg 1: "#0 supposed to be 1000"
At 1511 ms received msg 2: "#1 supposed to be 1500"

19270: drivers/at24cxxx: implement _mtd_at24cxxx_read_page r=benpicco a=HendrikVE
### Contribution description
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
READ of size 4 at 0x080774e0 thread T0
#0 0x804af5d in _auto_init_module /RIOT/sys/auto_init/auto_init.c:40
#1 0x804af5d in auto_init /RIOT/sys/auto_init/auto_init.c:339
#2 0x804b375 in main_trampoline /RIOT/core/lib/init.c:56
#3 0xf76bc7b8 in makecontext (/lib32/libc.so.6+0x4a7b8)
...
```
After applying this PR, the example can be build and run with llvm or gcc, with or without asan.

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. ``` > saul 2022-08-02 22:12:31,826 # saul 2022-08-02 22:12:31,827 # ID Class Name 2022-08-02 22:12:31,830 # #0 ACT_SWITCH LD1(green) 2022-08-02 22:12:31,832 # #1 ACT_SWITCH LD2(blue) 2022-08-02 22:12:31,834 # #2 ACT_SWITCH LD3(red) 2022-08-02 22:12:31,837 # #3 SENSE_BTN B1(User button) 2022-08-02 22:12:31,838 # #4 ACT_SERVO servo > saul write 4 0 2022-08-02 22:12:41,443 # saul write 4 0 2022-08-02 22:12:41,445 # Writing to device #4 - servo 2022-08-02 22:12:41,447 # Data: 0 2022-08-02 22:12:41,450 # [servo] setting 0 to 2949 (0 / 255) 2022-08-02 22:12:41,453 # data successfully written to device #4 > saul write 4 256 2022-08-02 22:12:45,343 # saul write 4 256 2022-08-02 22:12:45,346 # Writing to device #4 - servo 2022-08-02 22:12:45,347 # Data: 256 2022-08-02 22:12:45,351 # [servo] setting 0 to 6865 (255 / 255) 2022-08-02 22:12:45,354 # data successfully written to device #4 ``` Each write resulted in the MG90S servo that I connected to move to the corresponding position. ### Issues/PRs references Co-authored-by: Marian Buschsieweke <marian.buschsieweke@ovgu.de>
