* feat: Modify optimized compaction to cover edge cases
This PR changes the algorithm for compaction to account for the following
cases that were not previously accounted for:
- Many generations with a groupsize over 2 GB
- Single generation with many files and a groupsize under 2 GB
- Where groupsize is the total size of the TSM files in said shard directory.
- shards that may have over a 2 GB group size but
many fragmented files (under 2 GB and under aggressive
point per block count)

* feat: This PR adds -tsm file flag to export
Adds the ability to use influx_inspect export to export data from a single tsm file, for example influx_inspect export -out - -tsmfile 000000006-000000002.tsm.bad -database thermo -retention autogen.
There are a number of code paths in Compactor.write which
on error can lead to leaked file handles to temporary files.
This, in turn, prevents the removal of the temporary files until
InfluxDB is rebooted, releasing the file handles.

This PR adds an additional statistic "fluxQueryRespBytes" to the output of /debug/vars, in turn making it available to Telegraf and other monitoring tools.

* fix(influxd): update xxhash, avoid stringtoslicebyte in cache (#578)
* fix(influxd): update xxhash, avoid stringtoslicebyte in cache
This commit does 3 things:
* it updates xxhash from v1 to v2; v2 includes a assembly arm version of
Sum64
* it changes the cache storer to write with a string key instead of a
byte slice. The cache only reads the key which WriteMulti already has
as a string so we can avoid a host of allocations when converting back
and forth from immutable strings to mutable byte slices. This includes
updating the cache ring and ring partition to write with a string key
* it updates the xxhash for finding the cache ring partition to use
Sum64String which uses unsafe pointers to directly use a string as a
byte slice since it only reads the string. Note: this now uses an
assembly version because of the v2 xxhash update. Go 1.22 included new
compiler ability to recognize calls of Method([]byte(myString)) and not
make a copy but from looking at the call sites, I'm not sure the
compiler would recognize it as the conversion to a byte slice was
happening several calls earlier.
That's what this change set does. If we are uncomfortable with any of
these, we can do fewer of them (for example, not upgrade xxhash; and/or
not use the specialized Sum64String, etc).
For the performance issue in maz-rr, I see converting string keys to
byte slices taking between 3-5% of cpu usage on both the primary and
secondary. So while this pr doesn't address directly the increased cpu
usage on the secondary, it makes cpu usage less on both which still
feels like a win. I believe these changes are easier to review that
switching to a byte slice pool that is likely needed in other places as
the compiler provides nearly all of the correctness checks we need (we
are relying also on xxhash v2 being correct).
* helps #550
* chore: fix tests/lint
* chore: don't use assembly version; should inline
This 2 line change causes xxhash to use a purego Sum64 implementation
which allows the compiler to see that Sum64 only read the byte slice
input which them means is can skip the string to byte slice allocation
and since it can skip that, it should inline all the calls to
getPartitionStringKey and Sum64 avoiding 1 call to Sum64String which
isn't inlined.

This PR adds test and new method to clear out the bad shards list
the method will return the values of the shards that it cleared out
along with the errors. This is the first part in the feature
for adding a load-shards command to influxd-ctl.

This PR is like influxdata/influxdb#24613 but solves it with a setter
method for MaxLogFileSize which allows unexporting that value and
MaxLogFileAge. There are actually two places locks were needed in test
code. The behavior of production code is unchanged.

* fix: prevent retention service from hanging
Fix issue that can cause the retention service to hang waiting on a
`Shard.Close` call. When this occurs, no other shards will be deleted
by the retention service. This is usually noticed as an increase in
disk usage because old shards are not cleaned up.
The fix adds to new methods to `Store`, `SetShardNewReadersBlocked`
and `InUse`. `InUse` can be used to poll if a shard has active readers,
which the retention service uses to skip over in-use shards to prevent
the service from hanging. `SetShardNewReadersBlocked` determines if
new read access may be granted to a shard. This is required to prevent
race conditions around the use of `InUse` and the deletion of shards.
If the retention service skips over a shard because it is in-use, the
shard will be checked again the next time the retention service is run.
It can be deleted on subsequent checks if it is no longer in-use. If
the shards is stuck in-use, the retention service will not be able to
delete the shards, which can be observed in the logs for manual
intervention. Other shards can still be deleted by the retention service
even if a shard is stuck with readers.

ArrayCursors were ignoring errors, which led to panics when nil
cursors were operated on. This fix passes errors back up the stack
and uses them to enforce healthy cursor creation.
