Avi Kivity 88322086cb Merge "Add fuzzer-type unit test for range scans" from Botond ...

"
This series adds a fuzzer-type unit test for range scans, which
generates a semi-random dataset and executes semi-random range scans
against it, validating the result.
This test aims to cover a wide range of corner cases with the help of
randomness. Data and queries against it are generated in such a way that
various corner cases and their combinations are likely to be covered.

The infrastructure under range-scans have gone under massive changes in
the last year, growing in complexity and scope. The correctness of range
scans is critical for the correct functioning of any Scylla cluster, and
while the current unit tests served well in detecting any major problems
(mostly while developing), they are too simplistic and can only be
relied on to check the correctness of the basic functionality. This test
aims to extend coverage drastically, testing cases that the author of
the range-scan code or that of the existing unit tests didn't even think
exists, by relying on some randomness.

Fixes: #3954 (deprecates really)
