This API change refactors the usbdev API to supply buffers via the
usbdev_ep_xmit function. This changes from the usbdev_ep_ready call to allow
separate buffers per call. An usbdev_ep_buf_t pseudotype is available and must
be used when defining buffers used for endpoints to adhere to the DMA alignment
restrictions often required with usb peripherals.
Main advantage is that the usbdev peripherals no longer have to allocate
oversized buffers for the endpoint data, potentially saving multiple KiB
of unused buffer space. These allocations are now the responsibility of
the individual USB interfaces in the firmware

If we
-include Makefile.ci
and `Makefile.ci` does not exist, but we provide `make` with a way
on how to do so, it will try to create `Makefile.ci`.
This is not what we want, but I don't know how to disable this automagic.
So rename the target to `create-Makefile.ci` to avoid the conflict.
This adds a check to the usbus control stack to ensure that the amount
of data received with a setup request does not exceed the amount
indicated within the setup request
This adds a sanity check to the line coding request of the CDC ACM code
to chcek the length parameter in the setup request with the size of the
expected payload struct
This truncates the incomming frames to ETHERNET_FRAME_LEN and silently
discards the rest of the frame until the end of the frame. This should
be modified to an endpoint halt condition after #17090 is merged, but
for now this should be good enough.
Stalling the endpoint with the current stall implementation could cause
a ping of death scenario, so for now the data is truncated until the
above solution can be implemented.
Previously the test script relied on the exact sequence of numbers
returned by the used PRNG. This resulting e.g. in
```
$ USEMODULE=prng_musl_lcg make -C tests/pthread_barrier flash test
```
to fail, only because the order in which the children completed is
slightly different due to different sleep durations. This fixes the
issue.
