It offers a quickfix action for certain errors, includes a number of bug fixes and it
introduces a new warning by default (https://github.com/scala/scala/pull/10462).
In addition to the scala version bump, we also fix the new compiler warnings and
bump the scalafmt version (the previous version failed with the new scala version).

This includes TASTy Reader support for Scala 3.0.0. This makes it easier
for Kafka libraries to be used in Scala 3.0 projects
Release notes: https://github.com/scala/scala/releases/tag/v2.13.6
Reviewers: Ismael Juma <ismael@juma.me.uk>
Scala 2.13.4 restores default global `ExecutionContext` to 2.12 behavior
(to fix a perf regression in some use cases) and improves pattern matching
(especially exhaustiveness checking). Most of the changes are related
to the latter as I have enabled the newly introduced `-Xlint:strict-unsealed-patmat`.
More details on the code changes:
* Don't swallow exception in `ReassignPartitionsCommand.topicDescriptionFutureToState`.
* `RequestChannel.Response` should be `sealed`.
* Introduce sealed ClientQuotaManager.BaseUserEntity to avoid false positive
exhaustiveness warning.
* Handle a number of cases where pattern matches were not exhaustive:
either by marking them with @unchecked or by adding a catch-all clause.
* Workaround scalac bug related to exhaustiveness warnings in ZooKeeperClient
* Remove warning suppression annotations related to the optimizer that are no
longer needed in ConsumerGroupCommand and AclAuthorizer.
* Use `forKeyValue` in `AclAuthorizer.acls` as the scala bug preventing us from
using it seems to be fixed.
* Also update scalaCollectionCompat to 2.3.0, which includes minor improvements.

I had to fix several compiler errors due to deprecation of auto application of `()`. A related
Xlint config (`-Xlint:nullary-override`) is no longer valid in 2.13, so we now only enable it
for 2.12. The compiler flagged two new inliner warnings that required suppression and
the semantics of `&` in `@nowarn` annotations changed, requiring a small change in
one of the warning suppressions.
I also removed the deprecation of a number of methods in `KafkaZkClient` as
they should not have been deprecated in the first place since `KafkaZkClient` is an
internal class and we still use these methods in the Controller and so on. This
became visible because the Scala compiler now respects Java's `@Deprecated`
annotation.
Finally, I included a few minor clean-ups (eg using `toBuffer` instead `toList`) when fixing
the compilation warnings.
Noteworthy bug fixes in Scala 2.13.3:
* Fix 2.13-only bug in Java collection converters that caused some operations to perform an extra pass
* Fix 2.13.2 performance regression in Vector: restore special cases for small operands in appendedAll and prependedAll
* Increase laziness of #:: for LazyList
* Fixes related to annotation parsing of @Deprecated from Java sources in mixed compilation

Scala 2.13.2 introduces support for suppressing warnings,
which makes it possible to enable fatal warnings. This is
useful enough from a development perspective to justify
this change.
In addition, Scala 2.13.2 also has a Vector implementation
with significant performance improvements and encoding
of String matches to switches.
Reviewers: Manikumar Reddy <manikumar.reddy@gmail.com>
Highlights:
* Performance improvements in the ollections
library: algorithmic improvements and
changes to avoid unnecessary allocations.
* Performance improvements in the compiler.
* ASM was upgraded to 7.3.1, allowing the
optimizer to run on JDK 13+.

Removed quotes from LogDir variable generation as there are additional quotes in Line 127.
This caused problems when those batch files are invoked from a path that contains space characters.
Scala 2.12 has better support for newer Java versions and includes additional
compiler warnings that are helpful during development. In addition, Scala 2.11
hasn't been supported by the Scala community for a long time, the soon to be
released Spark 2.4.0 will finally support Scala 2.12 (this was the main reason
preventing many from upgrading to Scala 2.12) and Scala 2.13 is at the RC stage.
It's time to start recommending the Scala 2.12 build as we prepare support for
Scala 2.13 and start thinking about removing support for Scala 2.11.
In the meantime, Jenkins will continue to build all supported Scala versions (including
Scala 2.11) so the PR and trunk jobs will fail if people accidentally use methods
introduced in Scala 2.12.

It seems a tipo was made on a avariable for the log dir with commit 81e789ae3d. Then Windows tries to access by default the /log directory which of cause not exists.
klesta490 Is it ok so? Or was the tilde ~ intentional?
To test:
On Windows with the a fresh downloaded Kafka, adapt the properties:
* dataDir in config/zookeeper.properties with what you want, windows-compatible
* log.dirs in config/server.properties with what you want, windows-compatible
and executes:
bin\windows\zookeeper-server-start.bat config\zookeeper.properties

This is important because Bits.reserveMemory calls System.gc() hoping to free native
memory in order to avoid throwing an OutOfMemoryException. This call is currently
a no-op due to -XX:+DisableExplicitGC.
It's worth mentioning that -XX:MaxDirectMemorySize can be used to increase the
amount of native memory available for allocation of direct byte buffers.

Some of the recent changes to `kafka-run-class.sh` have not been applied to `kafka-run-class.bat`.
These recent changes include setting proper streams or connect classpaths. So any streams or connect use case that leverages `kafka-run-class.bat` would fail with an error like
```
Error: Could not find or load main class org.apache.kafka.streams.???

On Windows, the following output is seen when starting Zookeeper and Kafka servers:
```
'#' is not recognized as an internal or external command,
operable program or batch file.

This pull request makes a minor correction to the Windows `kafka-run-class.bat` script to replace the use of `#` with `rem`.

A few minor fixes to reconcile differences between the windows and unix versions of the kafka/zookeeper start scripts that were causing cross-platform inconsistencies during deployment.
- Resolve differences in CLASSPATH setup between .bat and .sh start scripts
- .bat start scripts honor externally provided KAFKA_HEAP_OPTS and KAFKA_LOG4J_OPTS consistent with .sh
- .bat start scripts configure log4j similar to .sh
