We had separate test files test_minmax.py and test_count.py but the
separate was artificial (and test_count.py even had one test using
min()). Now I that want to add another test for sum(), I don't know
where to put it. So in this patch I combine test_minmax.py and
test_count.py into one test file - test_aggregate.py, and we can
later add sum() tests in the same file.

now that Seastar can be built as shared libraries, we can use it for
faster development iteration with less disk usage.
in this change
* configure.py:
- 'build_seastar_shared_libs' is added as yet another mode value,
so different modes have its own setting. 'debug' and 'dev' have
this enabled, while other modes disable it.
- link scylla with rpath specified, so it can find `libseastar.so`
in build directory.
* install.sh: remove the rpath as the rpath in the elf image will
not be available after the relocatable package is installed, also
rpmbuild will error out when it uses check-rpaths to verify
the elf images (executables and shared libraries), as the rpath
encoded in them are not known ones. patchelf() will take care of
the shared libraries linked by the executables. so we don't need
to worry about libseastar.so or libseastar_testing.so.

Closes#12801
Recently, we overhauled the error handling of UNSET_VALUE in various
places where it is not allowed. This patch adds two more regression
tests for this error handling. Both tests pass on Scylla today, pass
on Cassandra, but fail on earlier Scylla (e.g., I tested 5.1.5):
The first test does INSERT into clustering key UNSET_VALUE.
An UNSET_VALUE is designed to skip part of the write - not an entire
write - so this attempt should fail - not silently be skipped.
The write indeed fails with an error on Cassandra, and on recent
Scylla, but silently did nothing in older Scylla which leads this
test to fail there.
The second test does the same thing with LWT (adding an "IF NOT EXISTS")
added to the insert. Scylla's failure here was even more spectacular -
it crashed (as reported in issue #13001) instead of silently skipping
the right. The test passes on Scylla today and on Cassandra, which
both report the failure cleanly.
Refs #13001.

Closes#13007
Cassandra is very strict in the CLUSTERING ORDER BY clause which it
allows when creating a materialized view - if it appears, it must
list all the clustering columns of the view. Scylla is less strict -
a subset of the clustering columns may be specified. But Scylla was
*too* lenient - a user could specify non-clustering columns and even
non-existent columns and Scylla would not fail the MV creation.
This patch fixes that - with it MV creation fails if anything besides
clustering columns are listed on CLUSTERING ORDER BY.
An xfailing test we had for this case no longer fails after this
patch so its xfail mark is removed. We also add a few more corner
cases to the tests.
This patch also fixs one C++ test which had exactly the error that this
patch detects - the test author tried to use the partition key, instead
of the clustering key, in CLUSTERING ORDER BY (this error had no effect
because the specified order, "asc", was the default anyway).

if we pass the key of the wrong type, it should reject.

* we validate the keys before returning the "token()" function.
* drop the "xfail" decorator from two of the tests. they pass
now after this fix.
* change the tests which previously passed the wrong number of

null, so they verify that "token()" should reject these

Node ops has the following procedure:
1 for node in sync_nodes
send prepare cmd to node
2 for node in sync_nodes
send heartbeat cmd to node
If any of the prepare cmd in step 1 takes longer than the heartbeat
watchdog timeout, the heartbeat in step 2 will be too late to update the
watchdog, as a result the watchdog will abort the operation.
To prevent slow prepare cmd kills the node operations, we can start the
heartbeat earlier in the procedure.

It's known that reading large cells in reverse cause large allocations.
Source: https://github.com/scylladb/scylladb/issues/11642
The loading is preliminary work for splitting large partitions into
fragments composing a run and then be able to later read such a run
in an efficiency way using the position metadata.
The splitting is not turned on yet, anywhere. Therefore, we can
temporarily disable the loading, as a way to avoid regressions in
stable versions. Large allocations can cause stalls due to foreground
memory eviction kicking in.
The default values for position metadata say that first and last
position include all clustering rows, but they aren't used anywhere
other than by sstable_run to determine if a run is disjoint at
clustering level, but given that no splitting is done yet, it
does not really matter.
Unit tests relying on position metadata were adjusted to enable
the loading, such that they can still pass.

All major compaction tasks will share some methods like
type or abort. The common part of the tasks should be
inherited from major_compaction_task_impl.
The initial intent was to reduce the fanout of shared_sstable.hh through
v.u.g.hh -> cql_test_env.hh chain, but it also resulted in some shots
around v.u.g.hh -> database.hh inclusion.
By and large:
- v.u.g.hh doesn't need database.hh
- cql_test_env.hh doesn't need v.u.g.hh (and thus -- the
shared_sstable.hh) but needs database.hh instead
- few other .cc files need v.u.g.hh directly as they pulled it via
cql_test_env.hh before
- add forward declarations in few other places

The sstable_directory now combines two activities:
* scans the list of files in /var/lib/data and generates sstable-s object from it
* maintains the found sstable-s throughout necessary processing (populate/reshard/reshape)
The former part is in fact storage-specific. If sstables are on a filesystem, then it should be scanned with listdir, there can be dangling files, like temp-TOC, pending deletion log and comonents not belonging to any TOCs. If sstables are on some other storage, then this part should work some other way.
Said that, the sstable_directory is to be split into two pieces -- lister and "processing state". The latter would (may?) require renaming the sstable_directory into something more relevant, but that's huge and intrusive change. For now, just collect the lister stuff in one place.
