Fixes a compilation failure caused by HADOOP-19098
Restore original sortRanges() method signature,
FileRange[] sortRanges(List<? extends FileRange>)
This ensures that google GCS connector will compile again.
It has also been marked as Stable so it is left alone
The version returning List<? extends FileRange>
has been renamed sortRangeList()

- Critical: remove the obsolete exclusion list from hadoop-common.
- Diligence: expand the hadoop-project exclusion list to exclude
all ch.qos.logback artifacts

1. The class WrappedIO has been extended with more filesystem operations
- openFile()
- PathCapabilities
- StreamCapabilities
- ByteBufferPositionedReadable
All these static methods raise UncheckedIOExceptions rather than
checked ones.
2. The adjacent class org.apache.hadoop.io.wrappedio.WrappedStatistics
provides similar access to IOStatistics/IOStatisticsContext classes
and operations.
Allows callers to:
* Get a serializable IOStatisticsSnapshot from an IOStatisticsSource or
IOStatistics instance
* Save an IOStatisticsSnapshot to file
* Convert an IOStatisticsSnapshot to JSON
* Given an object which may be an IOStatisticsSource, return an object
whose toString() value is a dynamically generated, human readable summary.
This is for logging.
* Separate getters to the different sections of IOStatistics.
* Mean values are returned as a Map.Pair<Long, Long> of (samples, sum)
from which means may be calculated.
There are examples of the dynamic bindings to these classes in:
org.apache.hadoop.io.wrappedio.impl.DynamicWrappedIO
org.apache.hadoop.io.wrappedio.impl.DynamicWrappedStatistics
These use DynMethods and other classes in the package
org.apache.hadoop.util.dynamic which are based on the
Apache Parquet equivalents.
This makes re-implementing these in that library and others
which their own fork of the classes (example: Apache Iceberg)
3. The openFile() option "fs.option.openfile.read.policy" has
added specific file format policies for the core filetypes
* avro
* columnar
* csv
* hbase
* json
* orc
* parquet
S3A chooses the appropriate sequential/random policy as a
A policy `parquet, columnar, vector, random, adaptive` will use the parquet policy for
any filesystem aware of it, falling back to the first entry in the list which
the specific version of the filesystem recognizes
4. New Path capability fs.capability.virtual.block.locations
Indicates that locations are generated client side
and don't refer to real hosts.

This is a followup to #6543 which ensures all test pass in configurations where
fs.s3a.performance.flags is set to "*" or contains "mkdirs"
Contributed by VJ Jasani
If the flag list in fs.s3a.performance.flags includes "mkdir"
then the safety check of a walk up the tree to look for a parent directory,
-done to verify a directory isn't being created under a file- are skipped.
This saves the cost of multiple list operations.

1. Configuration adds new method `getEnumSet()` to get a set of enum values from
a configuration string.
<E extends Enum<E>> EnumSet<E> getEnumSet(String key, Class<E> enumClass, boolean ignoreUnknown)
Whitespace is ignored, case is ignored and the value "*" is mapped to "all values of the enum".
If "ignoreUnknown" is true then when parsing, unknown values are ignored.
This is recommended for forward compatiblity with later versions.
2. This support is implemented in org.apache.hadoop.fs.s3a.impl.ConfigurationHelper -it can be used
elsewhere in the hadoop codebase.
3. A new private FlagSet class in hadoop common manages a set of enum flags.
It implements StreamCapabilities and can be probed for a specific option being set
(with a prefix)
S3A adds an option fs.s3a.performance.flags which builds a FlagSet with enum
type PerformanceFlagEnum
* which initially contains {Create, Delete, Mkdir, Open}
* the existing fs.s3a.create.performance option sets the flag "Create".
* tests which configure fs.s3a.create.performance MUST clear
fs.s3a.performance.flags in test setup.
Future performance flags are planned, with different levels of safety
and/or backwards compatibility.

The new property fs.s3a.encryption.context allow users to specify the AWS KMS Encryption Context to be used in S3A.
The value of the encryption context is a key/value string that will be Base64 encoded and set in the parameter ssekmsEncryptionContext from the S3 client.

Apache httpclient 4.5.x is the new default implementation of http connections;
this supports a large configurable pool of connections along with
the ability to limit their lifespan.
The networking library can be chosen using the configuration
option fs.azure.networking.library
The supported values are
- APACHE_HTTP_CLIENT : Use Apache HttpClient [Default]
- JDK_HTTP_URL_CONNECTION : Use JDK networking library
Important: unless the networking library is switched back to
the JDK, the apache httpcore and httpclient must be on the classpath
