This moves off use of the purged s3a://landsat-pds bucket, so fixing tests
which had started failing.
* Adds a new class, PublicDatasetTestUtils to manage the use of public datasets.
* The new test bucket s3a://usgs-landsat/ is requester pays, so depends upon
HADOOP-14661.
Consult the updated test documentation when running against other S3 stores.

S3A input stream support for the few fs.option.openfile settings.
As well as supporting the read policy option and values,
if the file length is declared in fs.option.openfile.length
then no HEAD request will be issued when opening a file.
This can cut a few tens of milliseconds off the operation.
The patch adds a new openfile parameter/FS configuration option
fs.s3a.input.async.drain.threshold (default: 16000).
It declares the number of bytes remaining in the http input stream
above which any operation to read and discard the rest of the stream,
"draining", is executed asynchronously.
This asynchronous draining offers some performance benefit on seek-heavy
file IO.

These changes ensure that sequential files are opened with the
right read policy, and split start/end is passed in.
As well as offering opportunities for filesystem clients to
choose fetch/cache/seek policies, the settings ensure that
processing text files on an s3 bucket where the default policy
is "random" will still be processed efficiently.
This commit depends on the associated hadoop-common patch,
which must be committed first.

The option fs.s3a.object.content.encoding declares the content encoding to be set on files when they are written; this is served up in the "Content-Encoding" HTTP header when reading objects back in.
This is useful for people loading the data into other tools in the AWS ecosystem which don't use file extensions to infer compression type (e.g. serving compressed files from S3 or importing into RDS)

Multi object delete of size more than 1000 is not supported by S3 and
fails with MalformedXML error. So implementing paging of requests to
reduce the number of keys in a single request. Page size can be configured
using "fs.s3a.bulk.delete.page.size"

Adds a new map type WeakReferenceMap, which stores weak
references to values, and a WeakReferenceThreadMap subclass
to more closely resemble a thread local type, as it is a
map of threadId to value.
Construct it with a factory method and optional callback
for notification on loss and regeneration.
WeakReferenceThreadMap<WrappingAuditSpan> activeSpan =
new WeakReferenceThreadMap<>(
(k) -> getUnbondedSpan(),
this::noteSpanReferenceLost);
This is used in ActiveAuditManagerS3A for span tracking.
Relates to
* HADOOP-17511. Add an Audit plugin point for S3A
* HADOOP-18094. Disable S3A auditing by default.

Part of HADOOP-17198. Support S3 Access Points.
HADOOP-18068. "upgrade AWS SDK to 1.12.132" broke the access point endpoint
translation.
Correct endpoints should start with "s3-accesspoint.", after SDK upgrade they start with
"s3.accesspoint-" which messes up tests + region detection by the SDK.

Add support for S3 Access Points. This provides extra security as it
ensures applications are not working with buckets belong to third parties.
To bind a bucket to an access point, set the access point (ap) ARN,
which must be done for each specific bucket, using the pattern
fs.s3a.bucket.$BUCKET.accesspoint.arn = ARN
* The global/bucket option `fs.s3a.accesspoint.required` to
mandate that buckets must declare their access point.
* This is not compatible with S3Guard.
Consult the documentation for further details.

See HADOOP-18091. S3A auditing leaks memory through ThreadLocal references
* Adds a new option fs.s3a.audit.enabled to controls whether or not auditing
is enabled. This is false by default.
* When false, the S3A auditing manager is NoopAuditManagerS3A,
which was formerly only used for unit tests and
during filsystem initialization.
* When true, ActiveAuditManagerS3A is used for managing auditing,
allowing auditing events to be reported.
* updates documentation and tests.
This patch does not fix the underlying leak. When auditing is enabled,
long-lived threads will retain references to the audit managers
of S3A filesystem instances which have already been closed.

Completely removes S3Guard support from the S3A codebase.
If the connector is configured to use any metastore other than
the null and local stores (i.e. DynamoDB is selected) the s3a client
will raise an exception and refuse to initialize.
This is to ensure that there is no mix of S3Guard enabled and disabled
deployments with the same configuration but different hadoop releases
-it must be turned off completely.
The "hadoop s3guard" command has been retained -but the supported
subcommands have been reduced to those which are not purely S3Guard
related: "bucket-info" and "uploads".
This is major change in terms of the number of files
changed; before cherry picking subsequent s3a patches into
older releases, this patch will probably need backporting
first.
Goodbye S3Guard, your work is done. Time to die.
Contributed by Steve Loughran.
With this update, the versions of key shaded dependencies are
jackson 2.12.3
httpclient 4.5.13
This backport patch does not include the TestArn changes needed
for the test to work with this version of the SDK; it is only
to be applied to branches without HADOOP-17198. "Support S3 Access Points".
If that patch is backported later, that test suite MUST be
updated to the latest version.

Cut modtime-based rename recovery as object modification time
is not updated during rename operation.
Applications will have to use etag API of HADOOP-17979
and implement it themselves.
Why not do the HEAD and etag recovery in ABFS client?
Cuts the IO capacity in half so kills job commit performance.
The manifest committer of MAPREDUCE-7341 will do this recovery
and act as the reference implementation of the algorithm.

Addresses transient failures in the following test classes:
* ITestAbfsStreamStatistics: Uses a filesystem level static instance to record read/write statistics, which also tracks these operations in other tests running in parallel. Marked for sequential-only run to avoid transient failure
* ITestAbfsRestOperationException: The use of a static member to track retry count causes transient failures when two tests of this class happen to run together. Switch to non-static variable for assertions on retry count

This switches the default behavior of S3A output streams
to warning that Syncable.hsync() or hflush() have been
called; it's not considered an error unless the defaults
are overridden.
This avoids breaking applications which call the APIs,
at the risk of people trying to use S3 as a safe store
of streamed data (HBase WALs, audit logs etc).
