This addresses two CVEs triggered by malformed archives
Important: Denial of Service CVE-2024-25710
Moderate: Denial of Service CVE-2024-26308

Clarifies behaviour of VectorIO methods with contract tests as well as
specification.
* Add precondition range checks to all implementations
* Identify and fix bug where direct buffer reads was broken
(HADOOP-19101; this surfaced in ABFS contract tests)
* Logging in VectoredReadUtils.
* TestVectoredReadUtils verifies validation logic.
* FileRangeImpl toString() improvements
* CombinedFileRange tracks bytes in range which are wanted;
toString() output logs this.
HDFS
* Add test TestHDFSContractVectoredRead
ABFS
* Add test ITestAbfsFileSystemContractVectoredRead
S3A
* checks for vector IO being stopped in all iterative
vector operations, including draining
* maps read() returning -1 to failure
* passes in file length to validation
* Error reporting to only completeExceptionally() those ranges
which had not yet read data in.
* Improved logging.
readVectored()
* made synchronized. This is only for the invocation;
the actual async retrieves are unsynchronized.
* closes input stream on invocation
* switches to random IO, so avoids keeping any long-lived connection around.
+ AbstractSTestS3AHugeFiles enhancements.
+ ADDENDUM: test fix in ITestS3AContractVectoredRead
Contains: HADOOP-19101. Vectored Read into off-heap buffer broken in fallback
implementation

If the option fs.s3a.committer.magic.track.commits.in.memory.enabled
is set to true, then rather than save data about in-progress uploads
to S3, this information is cached in memory.
If the number of files being committed is low, this will save network IO
in both the generation of .pending and marker files, and in the scanning
of task attempt directory trees during task commit.

This is a followup to #6406:
HADOOP-18980. S3A credential provider remapping: make extensible
It adds extra validation of key-value pairs in a configuration
option, with tests.

This reverts most of
HADOOP-18869: [ABFS] Fix behavior of a File System APIs on root path (#6003).
Calling getXAttr("/") or setXAttr("/") on an abfs container will fail with
`Operation failed: "The request URI is invalid.", HTTP 400 Bad Request`
This change is to ensure:
* Consistency across ADLS clients
* Consistency across authentication mechanisms.

Spotbugs is mistaken here as it doesn't observer the read/write locks used
to manage exclusive access to the maps.
* cache the value between checks
* tag as @VisibleForTesting
