This patch fixes 2 issues at one go:
First, Currently sstables::load clears the sharding metadata
(via open_data()), and so scylla-sstable always prints
an empty array for it.
Second, printing token values would generate invalid json
as they are currently printed as binary bytes, and they
should be printed simply as numbers, as we do elsewhere,
for example, for the first and last keys.

The doc links in scylla-sstable help output are static, so they always
point to the documentation of the latest stable release, not to the
documentation of the release the tool binary is from. On top of that,
the links point to old open-source documentation, which is now EOL.
Fix both problems: point link at the new source-available documentation
pages and make them version aware.

Interval map is very susceptible to quadratic space behavior when it's flooded with many entries overlapping all (or most of) intervals, since each such entry will have presence on all intervals it overlaps with.
A trigger we observed was memtable flush storm, which creates many small "L0" sstables that spans roughly the entire token range.
Since we cannot rely on insertion order, solution will be about storing sstables with such wide ranges in a vector (unleveled).
There should be no consequence for single-key reads, since upper layer applies an additional filtering based on token of key being queried.
And for range scans, there can be an increase in memory usage, but not significant because the sstables span an wide range and would have been selected in the combined reader if the range of scan overlaps with them.
Anyway, this is a protection against storm of memtable flushes and shouldn't be the common scenario.
It works both with tablets and vnodes, by adjusting the token range spanned by compaction group accordingly.
Fixes#23634.
We can backport this into 2024.2, 2025.1, but we should let this cook in master for 1 month or so.

Currently, nodetool repair command repairs both vnode and tablet keyspaces
if no keyspace is specified. We should use this command to repair
only vnode keyspaces, but this isn't easily accessible - we have to
explicitly run repair only on vnode keyspaces.
nodetool repair skips tablet keyspaces unless a tablet keyspace
is explicitely passed as an argument.

optimized_clang.sh trains the compiler using profile-guided optimization
(pgo). However, while doing that, it builds scylladb using its own profile
stored in pgo/profiles and decompressed into build/profile.profdata. Due
to the funky directory structure used for training the compiler, that
path is invalid during the training and the build fails.
The workaround was to build on a cloud machine instead of a workstation -
this worked because the cloud machine didn't have git-lfs installed, and
therefore did not see the stored profile, and the whole mess was averted.
To make this work on a machine that does have access to stored profiles,
disable use of the stored profile even if it exists.

Currently, the base_info may or may not be set in view schemas.
Even when it's set, it may be modified. This necessitates extra
checks when handling view schemas, as well as potentially causing
errors when we forget to set it at some point.
Instead, we want to make the base info an immutable member of view
schemas (inside view_info). The first step towards that is making
sure that all newly created schemas have the base info set.
We achieve that by requiring a base schema when constructing a view
schema. Unfortunately, this adds complexity each time we're making
a view schema - we need to get the base schema as well.
In most cases, the base schema is already available. The most
problematic scenario is when we create a schema from mutations:
- when parsing system tables we can get the schema from the
database, as regular tables are parsed before views
- when loading a view schema using the schema loader tool, we need
to load the base additionally to the view schema, effectively
doubling the work
- when pulling the schema from another node - in this case we can
only get the current version of the base schema from the local
database
Additionally, we need to consider the base schema version - when
we generate view updates the version of the base schema used for
reads should match the version of the base schema in view's base
info.
This is achieved by selecting the correct (old or new) schema in
`db::schema_tables::merge_tables_and_views` and using the stored
base schema in the schema_registry.

Any empty object of the json::json_list type has its internal
_set variable assigned to false which results in such objects
being skipped by the json::json_builder.
Hence, the json returned by the api GET//compaction_manager/compaction_history
does not contain the field `rows_merged` if a cell in the
system.compaction_history table is null or an empty list.
In such cases, executing the command `nodetool compactionhistory`
will result in a crash with the following error message:
`error running operation: rjson::error (JSON assert failed on condition 'false'`
The patch fixes it by checking if the json object contains the
`rows_merged` element before processing. If the element does
not exist, the nodetool will now produce an empty list.

GetInt() was observed to fail when the integer JSON value overflows the
int32_t type, which `GetInt()` uses for storage. When this happens,
rapidjson will assign a distinct 64 bit integer type to the value, and
attempting to access it as 32 bit integer triggers the wrong-type error,
resulting in assert failure. This was hit on the field where invoking
nodetool netstats resulted in nodetool crashing when the streamed bytes
amounts were higher than maxint.
To avoid such bugs in the future, replace all usage of GetInt() in
nodetool of GetInt64(), just to be sure.
A reproducer is added to the nodetool netstats crash.

Said fields in statistics are of type
`disk_array<uint32_t, disk_string<uint16_t>>` and currently are handled
as array of regular strings. However these fields store exploded
clustering keys, so the elements store binary data and converting to
string can yield invalid UTF-8 characters that certain JSON parsers (jq,
or python's json) can choke on. Fix this by treating them as binary and
using `to_hex()` to convert them to string. This requires some massaging
of the json_dumper: passing field offset to all visit() methods and
using a caller-provided disk-string to sstring converter to convert disk
strings to sstring, so in the case of statistics, these fields can be
intercepted and properly handled.
While at it, the type of these fields is also fixed in the
documentation.

We still have a number of issues to be solved for views with tablets.
Until they are fixed, we should prevent users from creating them,
and use the vnode-based views instead.
This patch prepares the feature for enabling views with tablets. The
feature is disabled by default, but currently it has no effect.
After all tests are adjusted to use the feature, we should depend
on the feature for deciding whether we can create materialized views
in tablet-enabled keyspaces.
The unit tests are adjusted to enable this feature explicitly, and it's
also added to the scylla sstable tool config - this tool treats all
tables as if they were tablet-based (surprisingly, with SimpleStrategy),
so for it to work on views, the new feature must be enabled.

Replace usages of `boost::algorithm::join()` with `fmt::join()` to improve
performance and reduce dependency on Boost. `fmt::join()` allows direct
formatting of ranges and tuples with custom separators without creating
intermediate strings.
When formatting comma-separated values into another string, fmt::join()
avoids the overhead of temporary string creation that
`boost::algorithm::join()` requires. This change also helps streamline
our dependencies by leveraging the existing fmt library instead of
Boost.Algorithm.
To avoid the ambiguity, some caller sites were updated to call
`seastar::format()` explicitly.

Artifact tests have been failing since the switch to the native nodetool, because ScyllaDB doesn't leave any IOCBs for tools. On some setups it will consume all of them and then nodetool and any other native app will refuse to start because it will fail to allocate IOCBs.
This PR fixes this by making use of the freshly introduced `--reserve-io-control-blocks` seastar option, to reserve IOCBs for tool applications. Since the `linux-aio` and `epoll` reactor backends require quite a bit of these, we enable the `io_uring` reactor backend and switch tools to use this backend instead. The `io_uring` reactor backend needs just 2 IOCBs to function, so the reserve of 10 IOCBs set up in this PR is good for running 5 tool applications in parallel, which should be more than enough.

With commits ed7d352e7d and bb1867c7c7, we now have input streams for both compressed and uncompressed SSTables that provide seamless checksum and digest checking. The code for these was based on `validate_checksums()`, which implements its own validation logic over raw streams. This has led to some duplicate code.
This PR deduplicates the uncompressed case by modifying `validate_checksums()` to use a checksummed input stream instead of a raw stream. The same cannot be done for compressed SSTables though. The reason is that `validate_checksums()` needs to examine the whole data file, even if an invalid chunk is encountered. In the checksummed case we support that by offloading the error handling logic from the data source via a function parameter. In the compressed data source we cannot do that because it needs to return decompressed data and decompression may fail if the data are invalid.
This PR also enables `validate_checksums()` to partially verify SSTables with just the per-chunk checksums if the digest is missing.
In more detail, this PR consists of:
* Port of some integrity checks from `do_validate_uncompressed()` to the checksummed data source. It should now be able to detect corruption due to truncated or appended chunks (expected number of chunks is retrieved from the CRC component).
* Introduction of `error_handler` parameter in checksummed data source and `data_stream()`.
* Refactoring of `validate_checksums()`. The JSON response of `sstable validate-checksums` was also modified to report a missing digest.
* Tests for `validate_checksums()` against SSTables with truncated data, appended data, invalid digests, or no digest.

This rather large patch series moves storage proxy and some adjacent
services (like migration manager) to use host ids to identify nodes rather
than ips. Messaging service gains a capability to address nodes by host
ids (which allows dropping translations from topology coordinator code
that worked on host ids already) and also makes sure that a node with
incorrect host id will reject a message (can happen during address
changes).
The series gets rid of the raft address map completely and replaces it with
the gossiper address map which is managed by the gossiper since translation
is now done in the layer below raft.

...
now that we are allowed to use C++23. we now have the luxury of using
`std::views::transform`.
in this change, we:
- replace `boost::adaptors::transformed` with `std::views::transform`
- use `fmt::join()` when appropriate where `boost::algorithm::join()`
is not applicable to a range view returned by `std::view::transform`.
- use `std::ranges::fold_left()` to accumulate the range returned by
`std::view::transform`
- use `std::ranges::fold_left()` to get the maximum element in the
range returned by `std::view::transform`
- use `std::ranges::min()` to get the minimal element in the range
returned by `std::view::transform`
- use `std::ranges::equal()` to compare the range views returned
by `std::view::transform`
- remove unused `#include <boost/range/adaptor/transformed.hpp>`
- use `std::ranges::subrange()` instead of `boost::make_iterator_range()`,
to feed `std::views::transform()` a view range.
to reduce the dependency to boost for better maintainability, and
leverage standard library features for better long-term support.
this change is part of our ongoing effort to modernize our codebase
and reduce external dependencies where possible.
limitations:
there are still a couple places where we are still using
`boost::adaptors::transformed` due to the lack of a C++23 alternative
for `boost::join()` and `boost::adaptors::uniqued`.
