Converts the deprecations to `deprecatedAndMaybeLog` to reduce the
number of times we log deprecations, since some of these could be called
at a high frequency (due to unconverted queries, aggs, etc)
This commit introduces a module for Kibana that exposes REST APIs that
will be used by Kibana for access to its system indices. These APIs are wrapped
versions of the existing REST endpoints. A new setting is also introduced since
the Kibana system indices' names are allowed to be changed by a user in case
multiple instances of Kibana use the same instance of Elasticsearch.
Additionally, the ThreadContext has been extended to indicate that the use of
system indices may be allowed in a request. This will be built upon in the future
for the protection of system indices.

With #50871 aggrgations should now be parsed directly by an
`ObjectParser` or `ConstructingObjectParser` without the need for the
ceremonial `parse` method. This removes 10 of those `parse` methods and
parses the aggregation directly from their `ObjectParser`.
Makes the following changes to the `stop` token filter docs:
* Updates description
* Adds a link to the related Lucene filter
* Adds detailed analyze snippet
* Updates custom analyzer and custom filter snippets
* Adds a list of predefined stop words by language

`MinAndMax` encapsulates min and max values for a shard. It uses generics to make sure that the values are of the same type and are also comparable. Though there are warnings whenever this class is currently used, which are addressed with this commit.

This field is a specialization of the `keyword` field for the case when all
documents have the same value. It typically performs more efficiently than
keywords at query time by figuring out whether all or none of the documents
match at rewrite time, like `term` queries on `_index`.
The name is up for discussion. I liked including `keyword` in it, so that we
still have room for a `singleton_numeric` in the future. However I'm unsure
whether to call it `singleton`, `constant` or something else, any opinions?
For this field there is a choice between
1. accepting values in `_source` when they are equal to the value configured
in mappings, but rejecting mapping updates
2. rejecting values in `_source` but then allowing updates to the value that
is configured in the mapping
This commit implements option 1, so that it is possible to reindex from/to an
index that has the field mapped as a keyword with no changes to the source.

Currently _rollup_search requires manage privilege to access. It should really be
a read only operation. This PR changes the requirement to be read indices privilege.
Resolves: #50245
ObjectParser allows you to declare a set of required fields, such that at least one
of the set must appear in an xcontent object for it to be valid. This commit adds
the similar concept of a set of exclusive fields, such that at most one of the set
must be present. It also enables required fields on ConstructingObjectParser, and
re-implements PercolateQueryBuilder.fromXContent() to use object parsing as
an example of how this works.
Backport: #52627
Add watcher to trigger server after index operation has succeeded,
instead of adding a watch to trigger service before
the actual index operation has performed on the shard level.
This logic is simpler to reason about in the case that a failure
does occur during the execution of an index operation on
the shard level.
Relates to #52453, but I think doesn't fix it, but makes it easier
to debug.
When notifying global checkpoint listeners, we have an opportunity to
early return if there are not any registered listeners. This is
important since it saves some allocations, and also saves forking some
empty work to another thread. This commit adds an early return from
notifying listeners if there are not any registered.

Makes the following updates to the EQL search tutorial:
* Adds an API response to the basic tutorial
* Adds an example using the `event_type_field` parm
* Adds an example using the `timestamp_field`parm
* Adds an example using the `query` parm
* Updates example dataset to support more EQL query variety
Makes the following changes to the `trim` token filter docs:
* Updates description
* Adds a link to the related Lucene filter
* Adds tip about removing whitespace using tokenizers
* Adds detailed analyze snippets
* Adds custom analyzer snippet
Adds a warning admonition stating that the `index_options` mapping
parameter is intended only for `text` fields.
Removes an outdated statement regarding default values for numeric
and other datatypes.
Fix NPE when closing a webserver that hasn't started correctly.
This can happen when ssl context isn't initialized. The server instance is then never set,
which causes an NPE that masks the actual failure.
Example stacktrace that would mask an actual failure:
```
java.lang.NullPointerException

Allow AffixSetting as validator dependencies. If a validator
specifies AffixSettings as a dependency, then `validate(T, Map)`
will have the concrete setting in a map.

Fixes: #52933
Adds reporting of memory usage for data frame analytics jobs.
This commit introduces a new index pattern `.ml-stats-*` whose
first concrete index will be `.ml-stats-000001`. This index serves
to store instrumentation information for those jobs.
Backport of #52778 and #52958
Closes#43990. Describe how to change the default GC settings without changing
the default `jvm.options`. Give examples using `jvm.options.d`, and
`ES_JAVA_OPTS` with Docker.
This commit removes a TODO in the IndexNameExpressionResolver that
indicated the API should use a Set instead of a List. However, this
TODO was not completely correct since the ordering of arguments matters
due to negations when evaluating wildcards and since we also allow
a list of patterns like `*,-foo,*`, which would have a different
meaning even when using a Set with insertion ordering.

IDEs can sometimes run annotation processors that leave files in
`src/main/generated/**/*.java`, causing Spotless to complain. Even
though this path ought not to exist, exclude it anyway in order to avoid
spurious failures.
Since version 8.4, `MMapDirectory` has an optimization to read long[]
arrays directly in little endian order, which postings leverage. So it'd
be more efficient to open postings with `MMapDirectory`.
I refactored a bit the existing logic to better explain why every listed
file extension is open with `mmap`.
Add `:qa:os` and `:benchmarks` to the list of automatically formatted
projects, and apply some manual fix-ups to polish it up.
In particular, I noticed that `Files.write(...)` when passed a list will
automaticaly apply a UTF-8 encoding and write a newline after each line,
making it easier to use than FileUtils.append. It's even available from
1.8.
Also, in the Allocators class, a number of methods declared thrown exceptions that IntelliJ reported were never thrown, and as far as I could see this is true, so I removed the exceptions.
* Move In, InPipe and InProcessor out of SQL to the common QL project.
* Move tests classes to the QL project.
* Create SQL dedicated In class to handle SQL specific data types.
* Update SQL classes to use the InPipe and InProcessor QL classes.
* Extract common Foldables methods in QL project.
* Be more explicit when folding and converting a foldable value, by
removing most of the code inside Foldables class.
