When purging regular tombstone consult the min_live_timestamp, if available.
This is safe since we don't need to protect dead data from resurrection, as it is already dead.
For shadowable_tombstones, consult the min_memtable_live_row_marker_timestamp,
if available, otherwise fallback to the min_live_timestamp.
If we see in a view table a shadowable tombstone with time T, then in any row where the row marker's timestamp is higher than T the shadowable tombstone is completely ignored and it doesn't hide any data in any column, so the shadowable tombstone can be safely purged without any effect or risk resurrecting any deleted data.
In other words, rows which might cause problems for purging a shadowable tombstone with time T are rows with row markers older or equal T. So to know if a whole sstable can cause problems for shadowable tombstone of time T, we need to check if the sstable's oldest row marker (and not oldest column) is older or equal T. And the same check applies similarly to the memtable.
If both extended timestamp statistics are missing, fallback to the legacy (and inaccurate) min_timestamp.

When we introduced optimized clang at 6e487a4, we dropped multiarch build on frozen toolchain, because building clang on QEMU emulation is too heavy.
Actually, even after the patch merged, there are two mode which does not build clang, --clang-build-mode INSTALL_FROM and --clang-build-mode SKIP.
So we should restore multiarch build only these mode, and keep skipping on INSTALL mode since it builds clang.
Since we apply multiarch on INSTALL_FROM mode, --clang-archive replaced
to --clang-archive-x86_64 and --clang-archive-aarch64.
Note that this breaks compatibility of existing clang archive, since it
changes clang root directory name from llvm-project to llvm-project-$ARCH.
Closes#20442Closesscylladb/scylladb#20444
before this change, we rely on `using namespace seastar` to use
`seastar::format()` without qualifying the `format()` with its
namespace. this works fine until we changed the parameter type
of format string `seastar::format()` from `const char*` to
`fmt::format_string<...>`. this change practically invited
`seastar::format()` to the club of `std::format()` and `fmt::format()`,
where all members accept a templated parameter as its `fmt`
parameter. and `seastar::format()` is not the best candidate anymore.
despite that argument-dependent lookup (ADT for short) favors the
function which is in the same namespace as its parameter, but
`using namespace` makes `seastar::format()` more competitive,
so both `std::format()` and `seastar::format()` are considered
as the condidates.
that is what is happening scylladb in quite a few caller sites of
`format()`, hence ADT is not able to tell which function the winner
in the name lookup:
```
/__w/scylladb/scylladb/mutation/mutation_fragment_stream_validator.cc:265:12: error: call to 'format' is ambiguous

143 | format(fmt::format_string<A...> fmt, A&&... a) {

```
in this change, we
change all `format()` to either `fmt::format()` or `seastar::format()`
with following rules:
- if the caller expects an `sstring` or `std::string_view`, change to
`seastar::format()`
- if the caller expects an `std::string`, change to `fmt::format()`.
because, `sstring::operator std::basic_string` would incur a deep
copy.
we will need another change to enable scylladb to compile with the
latest seastar. namely, to pass the format string as a templated
parameter down to helper functions which format their parameters.
to miminize the scope of this change, let's include that change when
bumping up the seastar submodule. as that change will depend on
the seastar change.

This PR introduces a new file data source implementation for uncompressed SSTables that will be validating the checksum of each chunk that is being read. Unlike for compressed SSTables, checksum validation for uncompressed SSTables will be active for scrub/validate reads but not for normal user reads to ensure we will not have any performance regression.
It consists of:
* A new file data source for uncompressed SSTables.
* Integration of checksums into SSTable's shareable components. The validation code loads the component on demand and manages its lifecycle with shared pointers.
* A new `integrity_check` flag to enable the new file data source for uncompressed SSTables. The flag is currently enabled only through the validation path, i.e., it does not affect normal user reads.
* New scrub tests for both compressed and uncompressed SSTables, as well as improvements in the existing ones.
* A change in JSON response of `scylla validate-checksums` to report if an uncompressed SSTable cannot be validated due to lack of checksums (no `CRC.db` in `TOC.txt`).

Change the return type of `sstable::validate_checksums()` from binary

status represents uncompressed SSTables without a CRC component (no
entry for CRC.db in the TOC).
Also, change the JSON response of `sstable validate-checksums` to expose
the new status. Replace the boolean value for valid/invalid checksums
with an object that contains two boolean keys: one that indicates if the
SSTable has checksums, and one that indicates if the checksums are valid

checksums.

Bind variables in CQL have two formats: positional (`?`) where a variable is referred to by its relative position in the statement, and named (`:var`), where the user is expected to supply a name->value mapping.
In 19a6e69001 we identified the case where a named bind variable appears twice in a query, and collapsed it to a single entry in the statement metadata. Without this, a driver using the named variable syntax cannot disambiguate which variable is referred to.
However, it turns out that users can use the positional call form even with the named variable syntax, by using the positional API of the driver. To support this use case, we add a configuration variable to disable the same-variable detection.
Because the detection has to happen when the entire statement is visible, we have to supply the configuration to the parser. We call it the `dialect` and pass it from all callers. The alternative would be to add a pre-prepare call similar to fill_prepare_context that rewrites all expressions in a statement to deduplicate variables.
A unit test is added.

under the hood, std::map::count() and std::map::contains() are nearly
identical. both operations search for the given key witin the map.
however, the former finds a equal range with the given
key, and gets the distance between the disntance between the begin
and the end of the range; while the later just searches with the given
key.
since scylla-nodetool is not a performance-critical application, the
minor difference in efficiency between these two operations is unlikely
to have a significant impact on its overall performance.
while std::map::count() is generally suitable for our need, it might be
beneficial to use a more appropriate API.
in this change, we use std::map::contains() in the place of
std::map::count() when checking for the existence of a paramter with

A dialect is a different way to interpret the same CQL statement.
Examples:
- how duplicate bind variable names are handled (later in this series)
- whether `column = NULL` in LWT can return true (as is now) or
whether it always returns NULL (as in SQL)
Currently, dialect is an empty structure and will be filled in later.
It is passed to query_processor methods that also accept a CQL string,
and from there to the parser. It is part of the prepared statement cache
key, so that if the dialect is changed online, previous parses of the
statement are ignored and the statement is prepared again.
The patch is careful to pick up the dialect at the entry point (e.g.
CQL protocol server) so that the dialect doesn't change while a statement
is parsed, prepared, and cached.

This adds minimal implementation of the start-restore API call.
The method starts a task that runs load-and-stream functionality against sstables from S3 bucket. Arguments are:
```
endpoint -- the ID in object_store.yaml config file
bucket -- the target bucket to get objects from
keyspace -- the keyspace to work on
table -- the table to work on
snapshot -- the name of the snapshot from which the backup was taken
```
The task runs in the background, its task_id is returned from the method once it's spawned and it should be used via /task_manager API to track the task execution and completion.
Remote sstables components are scanned as if they were placed in local upload/ directory. Then colelcted sstables are fed into load-and-stream.

before this change, `scylla sstable shard-of` didn't support tablets,
because:
- with tablets enabled, data distribution uses the scheduler
- this replaces the previous method of mapping based on vnodes and shard numbers
- as a result, we can no longer deduce sstable mapping from token ranges
in this change, we:
- read `system.tablets` table to retrieve tablet information
- print the tablet's replica set (list of <host, shard> pairs)
- this helps users determine where a given sstable is hosted

Some code, namely tests and schema-loader, don't have table at hand and
construct directory out of schema, sharder, path-to-sstables, etc. This
code doesn't work with any storage options other than local ones, so
there's no need (yet) to carry this argument over.

The command has a singl check for the missing keyspace and/or table
parameters and if the check fails, there is a combined error message.
Apparently this is confusing, so split the check so that missing
keyspace and missing table args have its own check and error message.

assert() is traditionally disabled in release builds, but not in
scylladb. This hasn't caused problems so far, but the latest abseil
release includes a commit [1] that causes a 1000 insn/op regression when
NDEBUG is not defined.
Clearly, we must move towards a build system where NDEBUG is defined in
release builds. But we can't just define it blindly without vetting
all the assert() calls, as some were written with the expectation that
they are enabled in release mode.
To solve the conundrum, change all assert() calls to a new SCYLLA_ASSERT()
macro in utils/assert.hh. This macro is always defined and is not conditional
on NDEBUG, so we can later (after vetting Seastar) enable NDEBUG in release
mode.
