Legacy Cassandra 3.x sstables use an old bloom filter format that is
incompatible with zero-copy streaming in Cassandra 5.0+. This patch
automatically detects sstables with the old bloom filter format
(pre-4.0) and disables zero-copy streaming for them, allowing legacy
sstables to be loaded via sstableloader without requiring manual flags.
The fix adds a version check in CassandraOutgoingFile.computeShouldStreamEntireSSTables()
that calls descriptor.version.hasOldBfFormat() to detect legacy sstables.

This commit adds a new configuration, data_disk_usage_keyspace_wide_protection_enabled, which ensures that if any node which replicates a given keyspace is full, all writes to that keyspace are blocked.

Closes#4547
add more flushing stats: partitions/rows, bytes rate, CPU and heap allocation for the flushing thread
avoid columns filtering overheads for unfilteredIterator
do not re-map colums in serializeRowBody if they haven't changed
reduce allocations during serialization of NativeClustering
add fast return for BTreeRow.hasComplexDeletion, avoid column.name.bytes.hashCode if not needed, avoid capturing lambda allocation in UnfilteredSerializer.serializeRowBody
check if Guardrails enabled at the beginning of writing, avoid hidden auto-boxing for logging of primitive parameters
split call sites for in Cell serialize logic, make isCounterCell cheaper (avoid megamorphic call + cache isCounterColumn)
invoke metadataCollector.updateClusteringValues only for first and last clustering key in a partition
enforce inlining for MinMaxIntTracker/MinMaxLongTracker

Based on the official documentation here (1), AsyncProfiler works best with these kernel parameters.
Not all CI environments have them set. That would fail the tests which run the startup check
if kernel parameters are not like that.
It might be empirically observed that some AsyncProfiler functionality works even without these
kernel parameters, it might be investigated in follow-up work if we should not relax these conditions a bit.

It is also possible to override them via nodetool if necessary.
This patch also fixes the computation of sampling ratio to not lose the precision.

Adds a compaction implementation utilizing new fixed allocation SSTable reader/writer implementations, and other purpose built code, leading to improved efficiencies.

By default the expiry time is calculated on each peer independently. It can be
made to converge by disabling gossip quarantine using the configuration setting
gossip_quarantine_disabled or via a hotprop on GossiperMBean.

Fix CQLSSTableWriter serialization of vector of date and time patch by Lukasz Antoniak; reviewed by Andres de la Pena, Yifan Cai for CASSANDRA-20979
Also Fix Cassandra:
- In memory size calculation for CommandsForKey include Unmanaged
- Accord load out-of-band cleanup should use SafeRedundantBefore
ALso Improve Cassandra:
- Report replay information on begin replay
- Improve AccordService shutdown
- Log command store RedundantBefore on shutdown
- Segment compaction should wait for readOrder barrier to replace segments, for additional safety
- Journal segments should share readOrder with sstables
Also Improve Accord:
- Iterate LocalListeners in order, so can query more effectively on node
- Refine AbstractReplay.minReplay/shouldReplay

Use a plain loop to check if it is ASCII symbol before going into more complicated UTF8 parsing.
Avoid ValueAccessor to get extra boost for the ASCII check, especially in non-monomorphic cases.
