To reduce test executable size and speed up compilation time, compile unit
tests into a single executable.
Here is a file size comparison of the unit test executable:
- Before applying the patch
$ du -h --exclude='*.o' --exclude='*.o.d' build/release/test/boost/ build/debug/test/boost/
11G build/release/test/boost/
29G build/debug/test/boost/
- After applying the patch
du -h --exclude='*.o' --exclude='*.o.d' build/release/test/boost/ build/debug/test/boost/
5.5G build/release/test/boost/
19G build/debug/test/boost/
It reduces executable sizes 5.5GB on release, and 10GB on debug.

Currently, `get_network_topology_options()` is using gossip data
and iterates over topology using IPs and not host IDs, which may
result in operating on inconsistent data.
This method's implemenations has been changed to instead use
`get_datacenters()`, which should always return consistent data.

Where the grammar supports IN, we add NOT IN. This includes the WHERE
clause and LWT IF clause.
Evaluation of NOT IN follows from IN.
In statement_restrictions analysis, they are different, as NOT IN
doesn't enable any clever query plan and must filter.
Some tests are added. An error message was changed ('in' changed to 'IN'),
so some tests are adjusted.

During the consolidation of per-suite pytest.ini files (commit 8bf62a086f),
the 'repair' marker was inadvertently dropped. This led to pytest warnings

PytestUnknownMarkWarning:
```

Currently, when finishing db::view::calculate_affected_clustering_ranges
we deoverlap, transform and copy all ranges prepared before. This
is all done within a single continuation and can cause stalls.
We fix this by adding yields after each transform and moving elements
to the final vector one by one instead of copying them all at the end.
After this change, the longest continuation in this code will be
deoverlapping the initial ranges (and one transform). While it has
a relatively high computational complexity (we sort all ranges), it
should execute quickly because we're operating on views there and
we don't need to copy the actual bytes. If we encounter a stall there,
we'll need to implement an asynchronous `deoverlap` method.

Enables abortable interface and propagates abort_source to all s3 objects used for reading the restore data.
Note: because restore is done on each shard, we have to maintain a per-shard abort source proxy for each, and do a background per-shard abort on abort call. This is synced at the end of "run()".
Abort source is added as an optional parameter to s3 storage and the s3 path in distributed loader.
There is no attempt to "clean up" an aborted restore. As we read on a mutation level from remote sstables, we should not cause incomplete sstables as such, even though we might end up of course with partial data restored.

When running clang-include-cleaner, the tool performs static analysis by
"compiling" specified source files. Previously, non-existent included headers
caused the tool to skip source files, reducing the effectiveness of unused
include detection.
Problem:
- Header files like 'rust/wasmtime_bindings.hh' were not pre-generated
- Compilation errors led to skipping source file analysis
```
/__w/scylladb/scylladb/lang/wasm.hh:15:10: fatal error: 'rust/wasmtime_bindings.hh' file not found
15 | #include "rust/wasmtime_bindings.hh"
| ^~~~~~~~~~~~~~~~~~~~~~~~~~~
Skipping file /__w/scylladb/scylladb/lang/wasm.hh due to compiler errors. clang-include-cleaner expects to work on compilable source code.
1 error generated.
```
- This significantly reduced clang-include-cleaner's coverage
Solution:
- Build the `wasmtime_bindings` target to generate required header files
- Ensure all necessary headers are created before running static analysis
- Enable full source file checking for unused includes
By generating headers before analysis, we prevent skipping of source files
and improve the comprehensiveness of our include cleaner workflow.

This test was added in PR #19789 but was disabled with xfail because of
the bug with way truncate saved the commit log replay positions. More
specifically, the replay positions for shards that had no mutations were
saved to system.truncated with shard_id == 0, regardless for which shard
it was actually saved for (see #21719).
The bug was fixed in #21722, so this change removes the xfail tag from
the test.

The data resolved has to apply all mutations from all replica to a
single mutation. In the extreme case, when all rows are dead, the
mutations can have around 10K rows in them. This is not a huge amount,
but it is enough to cause moderate stalls of <20ms.
To avoid this, use the gentle variant of apply(), which can yield in the
middle.

This patch includes more tests (in Python) that I wrote while implementing the Alternator UpdateTable feature for adding a GSI to an existing table (https://github.com/scylladb/scylladb/issues/11567).
I explain each of these tests in the separate patches below, but basically they fall into two types:
1. Tests which pass with today's materialized views and Alternator GSI/LSI, and serve to ensure that whatever changes I do to the view update implementation, doesn't break corner cases that already worked.
2. Tests for the UpdateTable feature in Alternator which doesn't work today so xfail - and will need to work for #11567. We already had a few tests for this, but here I add more and improve coverage of various corner cases I discovered while implementing the featue.
I already have a working prototype for #11567 which passes all these tests. Many of these tests helped exposed various bugs in earlier versions of my code.

When sending by ID we should check that we do not translate our old
address to our ID and sending locally. mark_alive should not be called
with node's old ip anyway.
This series attempts to get read of flakiness in `cache_algorithm_test` by solving two problems.
Problem 1:
The test needs to create some arbitrary partition keys of a given size. It intends to create keys of the form:
0x0000000000000000000000000000000000000000...
0x0100000000000000000000000000000000000000...
0x0200000000000000000000000000000000000000...
But instead, unintentionally, it creates partially initialized keys of the form: 0x0000000000000000garbagegarbagegarbagegar...
0x0100000000000000garbagegarbagegarbagegar...
0x0200000000000000garbagegarbagegarbagegar...
Each of these keys is created several times and -- for the test to pass -- the result must be the same each time.
By coincidence, this is usually the case, since the same allocator slots are used. But if some background task happens to overwrite the allocator slot during a preemption, the keys used during "SELECT" will be different than the keys used during "INSERT", and the test will fail due to extra cache misses.
Problem 2:
Cache stats are global, so there's no good way to reliably
verify that e.g. a given read causes 0 cache misses,
because something done by Scylla in a background can trigger a cache miss.
This can cause the test to fail spuriously.
With how the test framework and the cache are designed, there's probably
no good way to test this properly. It would require ensuring that cache
stats are per-read, or at least per-table, and that Scylla's background
activity doesn't cause enough memory pressure to evict the tested rows.
This patch tries to deal with the flakiness without deleting the test
altogether by letting it retry after a failure if it notices that it
can be explained by a read which wasn't done by the test.
(Though, if the test can't be written well, maybe it just shouldn't be written...)
