This fixes two problems with S3Guard authoritative mode and
the auth directory flags which are stored in DynamoDB.
1. mkdirs was creating dir markers without the auth bit,
forcing needless scans on newly created directories and
files subsequently added; it was only with the first listStatus call
on that directory that the dir would be marked as authoritative -even
though it would be complete already.
2. listStatus(path) would reset the authoritative status bit of all
child directories even if they were already marked as authoritative.
Issue #2 is possibly the most expensive, as any treewalk using listStatus
(e.g globfiles) would clear the auth bit for all child directories before
listing them. And this would happen every single time...
essentially you weren't getting authoritative directory listings.
For the curious, that the major bug was actually found during testing
-we'd all missed it during reviews.
A lesson there: the better the tests the fewer the bugs.
Maybe also: something obvious and significant can get by code reviews.

This is a regression caused by HADOOP-16759.
The test TestHarFileSystem uses introspection to verify that HarFileSystem
Does not implement methods to which there is a suitable implementation in
the base FileSystem class. Because of the way it checks this, refactoring
(protected) FileSystem methods in an IDE do not automatically change
the probes in TestHarFileSystem.
The changes in HADOOP-16759 did exactly that, and somehow managed
to get through the build/test process without this being noticed.
This patch fixes that failure.
Caused by and fixed by Steve Loughran.

This adds a new configuration option fs.s3a.connection.request.timeout
to declare the time out on HTTP requests to the AWS service;
0 means no timeout.
Measured in seconds; the usual time suffixes are all supported
Important: this is the maximum duration of any AWS service call,
including upload and copy operations. If non-zero, it must be larger
than the time to upload multi-megabyte blocks to S3 from the client,
and to rename many-GB files. Use with care.

* Enhanced builder + FS spec
* s3a FS to use this to skip HEAD on open
* and to use version/etag when opening the file
works with S3AFileStatus FS and S3ALocatedFileStatus
Introduces `openssl` as an option for `fs.s3a.ssl.channel.mode`.
The new option is documented and marked as experimental.
For details on how to use this, consult the peformance document
in the s3a documentation.
This patch is the successor to HADOOP-16050 "S3A SSL connections
should use OpenSSL" -which was reverted because of
incompatibilities between the wildfly OpenSSL client and the AWS
HTTPS servers (HADOOP-16347). With the Wildfly release moved up
to 1.0.7.Final (HADOOP-16405) everything should now work.
Related issues:
* HADOOP-15669. ABFS: Improve HTTPS Performance
* HADOOP-16050: S3A SSL connections should use OpenSSL
* HADOOP-16371: Option to disable GCM for SSL connections when running on Java 8
* HADOOP-16405: Upgrade Wildfly Openssl version to 1.0.7.Final

Adds one extra test to the ABFS close logic, to explicitly
verify that the close sequence of FilterOutputStream is
not going to fail.
This is just a due-diligence patch, but it helps ensure
that no regressions creep in in future.
