[Intel-gfx] [PATCH i-g-t v3 00/19] tests/core_hotunplug: Fixes and enhancements

[Janusz Krzysztofik]

Clean up the test code, add some new basic subtests, then unblock
unbind test variants.

One patch has been renamed, three new patches added to the series, and
one more patch form a formerly submitted series with new subtests
included.

@Michał: Since most v2/v3 updates are trivial, I've preserved your
v1/v2 Reviewd-by: except for a few patches with non-trivial changes,
where I marked your R-b as v1/v2 applicable.  Please have a look and
confirm if you are still OK with them.

@Tvrtko: Please support my attempt to remove the unbind test variants
from the blocklist.

@Petri, @Martin: Please give me your green lite for merging this
series if you have no objections.

Thanks,
Janusz
