* Windows doesn't want the
macro _JNI_IMPORT_OR_EXPORT_
to be defined in the function
definition. It fails to compile with
the following error -
"definition of dllimport function
not allowed".
* However, Linux needs it. Hence,
we're going to add this macro
based on the OS.
* Also, we'll be compiling the `hdfs`
target as an object library so that
we can avoid linking to `jvm`
library for `get_jni_test` target.

ChecksumFileSystem creates the chunked ranges based on the checksum chunk size and then calls
readVectored on Raw Local which may lead to overlapping ranges in some cases.

This sets a different timeout for data upload PUT/POST calls to all
other requests, so that slow block uploads do not trigger timeouts
as rapidly as normal requests. This was always the behavior
in the V1 AWS SDK; for V2 we have to explicitly set it on the operations
we want to give extended timeouts.
Option: fs.s3a.connection.part.upload.timeout
Default: 15m

* HttpReferrerAuditHeader is thread safe, copying the lists/maps passed
in and using synchronized methods when necessary.
* All exceptions raised when building referrer header are caught
and swallowed.
* The first such error is logged at warn,
* all errors plus stack are logged at debug

Adds new option
s3a.cross.region.access.enabled
Which is true by default
This enables cross region access as a separate config and enable/disables it irrespective of region/endpoint is set.

This moves Hadoop to Apache commons-collections4.
Apache commons-collections has been removed and is completely banned from the source code.

As part of work done under HADOOP-19120 [ABFS]: ApacheHttpClient adaptation as network library - ASF JIRA
Apache HTTP Client was introduced as an alternative Network Library that can be used with ABFS Driver. Earlier JDK Http Client was the only supported network library.
Apache HTTP Client was found to be more helpful in terms of controls and knobs it provides to manage the Network aspects of the driver better. Hence, the default Network Client was made to be used with the ABFS Driver.
Recently while running scale workloads, we observed a regression where some unexpected wait time was observed while establishing connections. A possible fix has been identified and we are working on getting it fixed.
There was also a possible NPE scenario was identified on the new network client code.
Until we are done with the code fixes and revalidated the whole Apache client flow, we would like to make JDK Client as default client again. The support will still be there, but it will be disabled behind a config.

Disables all logging below error in the AWS SDK Transfer Manager.
This is done in ClientManagerImpl construction so is automatically done
during S3A FS initialization.
ITests verify that
* It is possible to restore the warning log. This verifies the validity of
the test suite, and will identify when an SDK update fixes this regression.
* Constructing an S3A FS instance will disable the logging.
The log manipulation code is lifted from Cloudstore, where it was used to
dynamically enable logging. It uses reflection to load the Log4J binding;
all uses of the API catch and swallow exceptions.
This is needed to avoid failures when running against different log backends
This is an emergency fix -we could come up with a better design for
the reflection based code using the new DynMethods classes.
But this is based on working code, which is always good.
