19645: sys/isrpipe: Replace xtimer with ztimer_usec r=benpicco a=MrKevinWeiss
### Contribution description
Getting ready for the xtimer dep.
### Testing procedure
Green murdock, there is no explicit test for isrpipe but since it runs xtimer compat it should operate the same.

19693: sys/color: extend unittest and fix module r=maribu a=kfessel
### Contribution description
this extends the unittest for sys_color testing more colors
### Testing procedure
```
RIOT_tree/tests/unittests$ make tests-color test
```
will fail since our `rgb2hsv` implementation is wrong (or is using an other colorspace than hsv2rgb (without documenting))
the new `hsv2rgb` test will succeed
### Issues/PRs references
#19614 was the reason i had a look at this
#1315 added the rgb2hsv and hsv2rgb function
#9940 added the test for black special case
https://www.vagrearg.org/content/hsvrgb << some optimization for that function (avoiding float)

19687: tests/unittests: remove old workaround for SAML1X and gcc9.X bug r=maribu a=dylad
### Contribution description
This reverts #13462, this workaround is no longer needed with newer GCC version.
### Testing procedure
Try to compile tests/unittests for `saml11-xpro` or `saml10-xpro`
### Issues/PRs references
This is a revert of #13462.

19610: drivers/periph/rtc: improve doc on rtc_set_alarm r=maribu a=maribu
### Contribution description
- point out behavior on denormalized time stamps
- use errno codes to indicate errors (and adapt the few instances of actual error handling to use them)
19670: cpu/stm32: stm32f4 BRR from BSRR r=maribu a=kfessel
### Contribution description
sometimes one wants to save one instruction :)
just write the bits we need to write.
### Testing procedure
tests/periph/gpio_ll tests this
### Issues/PRs references
`@maribu` might know some reference
maybe #19407

19601: SUIT: Prepared manifests r=chrysn a=chrysn
### Contribution description
While SUIT can generally be used already with manifests that are "dropped into memory" (by any mechanism), the convenient SUIT worker thread mechanism so far could not be used with it.
This adds the suit_worker_try_prepare / suit_worker_trigger_prepared
pair for using the SUIT worker, and breaks suit_handle_manifest_buf out
of suit_handle_url (where the latter now calls the former).
#### By-catch
As part of factoring out reaping of the zombie worker thread, a locking
error that deadlocks the SUIT worker in case the race between the mutex
being unlocked and the thread being reaped hits the necessary handling
code is fixed (and mutex_unlock is called in the error path).
### Testing procedure
SUIT tests should pass.
https://github.com/RIOT-OS/RIOT/pull/19659 provides a demo of how the new API is used.
### Issues/PRs references
I think that the currently employed mechanism of having a resource to which a URL with the manifest gets posted is contrary to the design goals of SUIT -- the signed manifest should be what justifies the device to spend resources (eg. get data from a server), not a URI that is just *not* signed.
This PR makes it easier to implement a resource to which the manifest can be POSTed, rather than a CoAP URI that represents the manifest, as is proposed (but not mature) in
https://github.com/RIOT-OS/RIOT/pull/19659.
