* fix(restore): fix race condition which causes restore command to fail
Fixes a race condition in the restore code path that causes shard data restores
to fail. When the bug occurs, `Error while freeing cold shard resources`
appears in the log files.
fixes issue #15323
SHOW TAG KEYS FROM "foo" where bar="misquoted" is
erroneous, because the tag value must be enclosed
in single, not double, quotes. Although this
correctly returns no tag keys, it is very
inefficient and has cause out-of-memory failures
at a customer. This fix short-circuits the query.

If os.Link fails with syscall.ENOTSUP, then the file
system does not support links, and we must make copies
to snapshot files for backup. We also automatically make
copies instead of link on Windows, because although it
makes links, their semantics are different from Linux.

Dump all active queries to the log when a SIGTERM
is received and the termination-query-log flag is
true in the coordinator section of the config. The
default is false.
On Windows, make copies of files for snapshots, because
Go does not support the FILE_SHARE_DELETE flag which
allows files (and links) to be deleted while open. This
causes temporary directories to be left behind after
backups.

The tsmBatchKeyIterator discards excessive errors to avoid
out-of-memory crashes when compacting very corrupt files.
Any error beyond DefaultMaxSavedErrors (100) will be
discarded instead of appended to the error slice.

executeQuery() iterates over statements until each is
processed or if an error is encountered that causes
the loop to exit pre-maturely. It should return
ErrNotExecuted for each remaining statement in the
query

When the compaction planner runs, if it cannot acquire
a lock on the files it plans to compact, it returns a
nil list of compaction groups. This, in turn, sets the
engine statistics for compactions queues to zero,
which is incorrect. Instead, use the length of pending
files which would have been returned.

This fix ensures that memory-mapped files are not released
before pointers into them are copied into heap memory.
MeasurementNamesByExpr() and MeasurementNamesByPredicate() can
cause panics by copying memory from mmapped files that have been
released. The functions they call use iterators to files which
are closed (releasing the mmapped files) before the memory is
safely copied to the heap.
