Make sure the keys are full prefixes as it is expected to be the case
for rows. At severeal occasions we have seen empty row keys make their
ways into the sstables, despite the fact that they are not allowed by
the CQL frontend. This means that such empty keys are possibly results
of memory corruption or use-after-{free,copy} errors. The source of the
corruption is impossible to pinpoint when the empty key is discovered in
the sstable. So this patch adds checks for such keys to places where
mutations are built: when building or unserializing mutations.
The test row_cache_test/test_reading_of_nonfull_keys needs adjustment to
work with the changes: it has to make the schema use compact storage,
otherwise the non-full changes used by this tests are rejected by the
new checks.

If you can use an existing folder, consider adding your test to it. New folders should be used for new large categories/subsystems, or when the test environment is significantly different from some existing suite, e.g. you plan to start scylladb with different configuration, and you intend to add many tests and would like them to reuse an existing Scylla cluster (clusters can be reused for tests within the same folder).
To add a new folder, create a new directory, and then
copy & edit its suite.ini.
