During the investigation of scylladb/scylladb#20282, it was discovered that implementations of speculating read executors have undefined behavior when called with an incorrect number of read replicas. This PR introduces two levels of condition checking:
- Condition checking in speculating read executors for the number of replicas.
- Checking the consistency of the Effective Replication Map in filter_for_query(): the map is considered incorrect if the list of replicas contains a node from a data center whose replication factor is 0.
Please note: This PR does not fix the issue found in scylladb/scylladb#20282; it only adds condition checks to prevent undefined behavior in cases of inconsistent inputs.

During split prepare phase, there will be more than 1 compaction group with
overlapping token range for a given replica.
Assume tablet 1 has sstable A containing deleted data, and sstable B containing
a tombstone that shadows data in A.
Then split starts:
1) sstable B is split first, and moved from main (unsplit) group to a
split-ready group
2) now compaction runs in split-ready group before sstable A is split
tombstone GC logic today only looks at underlying group, so compaction is step
2 will discard the deleted data in A, since it belongs to another group (the
unsplit one), and so the tombstone can be purged incorrectly.
To fix it, compaction will now work with all uncompacting sstables that belong
to the same replica, since tombstone GC requires all sstables that possibly
contain shadowed data to be available for correct decision to be made.

A new header provides `constexpr` functions to retrieve build
type information: `get_build_type()`, `is_release_build()`,
and `is_debug_build()`. These functions are useful when adding
changes that should be enabled at compile time only for
specific build types.

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.

It is unsafe to restrict the sync nodes for repair to the source data center if it has too low replication factor in network_topology_replication_strategy, or if other nodes in that DC are ignored.
Also, this change restricts the usage of source_dc to `network_topology` and `everywhere_topology`
strategies, as with simple replication strategy
there is no guarantee that there would be any
more replicas in that data center.

flat_mutation_reader_v2 was introduced in a pair of commits in 2021:
e3309322c3 "Clone flat_mutation_reader related classes into v2 variants"
08b5773c12 "Adapt flat_mutation_reader_v2 to the new version of the API"
as a replacement for flat_mutation_reader, using range_tombstone_change
instead of range_tombstone to represent represent range tombstones. See
those commits for more information.
The transition was incremental; the last use of the original
flat_mutation_reader was removed in 2022 in commit
026f8cc1e7 "db: Use mutation_partition_v2 in mvcc"
In turn, flat_mutation_reader was introduced in 2017 in commit
748205ca75 "Introduce flat_mutation_reader"
To transition from a mutation_reader that nested rows within
a partition in a separate stream, to a flat reader that streamed
partitions and rows in the same stream.
Here, we reclaim the original name and rename the awkward
flat_mutation_reader_v2 to mutation_reader.
Note that mutation_fragment_v2 remains since we still use the original
for compatibilty, sometimes.
Some notes about the transition:
- files were also renamed. In one case (flat_mutation_reader_test.cc), the
rename target already existed, so we rename to
mutation_reader_another_test.cc.
- a namespace 'mutation_reader' with two definitions existed (in
mutation_reader_fwd.hh). Its contents was folded into the mutation_reader
class. As a result, a few #includes had to be adjusted.

before this change, we use runtime format string to format error
messages. but it does not have the compile time format check.
if we pass arguments which are not formattable, {fmt} throws at
runtime, instead of error out at compile-time. this could be very
annoying, because we format error messages at the error handling
path. but if user ends up seeing an exception for {fmt} instead
of a nice error message, it would be far from helpful.
in this change, we
- use compile-time format string
- fix two caller sites, where we pass `std::exception_ptr` to
{fmt}, but `std::exception_ptr` is not formattable by {fmt} at
the time of writing. we do have operator<< based formatter for
it though. so we delegate to `fmt::streamed` to format it.

The schema of the sstable can be interesting, so log it with trace
level. Unfortunately, this is not the nice CQL statement we are used to
(that requires a database object), but the not-nearly-so-nice CFMetadata
printout. Still, it is better then nothing.
When auto-detecting the schema of the sstable, if all other methods
failed, load the schema from the sstable's serialization header. This
schema is incomplete. It is just enough to parse and display the content
of the sstable. Although parsing and displaying the content of the
sstable is all scylla-sstable does, it is more future-compatible to us
the full schema when possible. So the always-available but minimal
schema that each sstable has on itself, is used just as a fallback.
The test which tested the case when all schema load attempts fail,
doesn't work now, because loading the serialization header always
succeeds. So convert this test into two positive tests, testing the
serialization header schema fallback instead.
Allows loading the schema from an sstable's serialization header. This
schema is incomplete, but it is enough to parse and display the content
of the sstable.

This feature corrected how we store the token in secondary indexes. It
was introduced in 7ff72b0ba5 (2020; 4.4) and can now be assumed present
everywhere. Note that we still support indexes created with the old format.
Currently, invoking `nodetool ring` on a tablet keyspace fails with an error, because it doesn't pass the required table parameter to `/storage_service/ownership/{keyspace}`. Further to this, the command will currently always output the vnode ring, regardless of the keyspace and table parameter. This series fixes this, adding tablet support to `/storage_service/tokens_endpoint`, which will now return the tablet ring (tablet token -> tablet primary replica mapping) if the new keyspace and table parameters are provided.
`nodetool status` also gets a touch-up, to provide the tablet ring's token count (the tablet count) when invoked with a tablet keyspace and table.

We move consistent cluster management out of experimental and

In 6.0, the topology upgrade procedure will be manual and

Therefore, we need to continue testing the gossip-based topology.

Add a bin/nodetool and install it to bin/ in install.sh. This script
simply forwards to scylla nodetool and it is the replacement for the
Java nodetool, which is dropped from the java-tools's install.sh, in the
submodule update also included in this patch.
With this change, we now hardwire the usage of the native nodetool, as
*the* nodetool, with the intermediary nodetool wrapper script removed
from the picture.
Bash completion was copied from the java tools repository and it is now
installed by the scylla package, together with nodetool.
The Java nodetool is still available as as a fall-back, in case the
native nodetool has problems, at the path of
/opt/scylladb/share/cassandra/bin/nodetool.
Testing
I tested upgrades on a DEB and RPM distro: Ubuntu and Fedora.
First I installed scylla-5.4, then I installed the packages for this PR.
On Ubuntu, I had to use dpkg -i --auto-deconfigure, otherwise, dpkg would
refuse to install the new packages because they break the old ones. No
extra flags were required on Fedora.
In both cases, /usr/bin/nodetool was changed from a thunk calling the
Java nodetool (from 5.4) to the native launcher script from this PR.
/opt/scylladb/share/cassandra/bin/nodetool remained in place and still
works after the upgrade.
I also verified that --nonroot installs also work. Nodetool works both
when called with an absolute path, or when ~/scylladb/bin is added to
$PATH.
