Make it possible to "finish" with fewer bytes than what was "claimed".
This was possible before on the get side, but the put side was
cummulative wrt finish. The revamp made it cummulative on both sides.
Turns out that existing users rely on the opposite behavior which is
more logical and useful. So make both sides that way.
Adjust documentation, test case and users accordingly.

Replace all get_dev_data()/get_dev_config() accessor utilities with
dev->data and dev->config.

Taking random numbers from hardware may be time consuming thus
it was deferred to a work queue. On the other hand, taking them
from software algorithm is fast. Use xoshiro128++ when enabled,
instead of real random numbers from hardware RNG generator. They
are use for random intervals in the test so no security concerns
here.

Busy simulator is using counter device and entropy device to
generate random cpu load. Counter device cofiguration can be
used to set cpu load interrupt priority and optional pin that
can be set during the load.
