Part of HADOOP-18469 and the hardening of XML/XSL parsers.
Followup to the main HADOOP-18575 patch, to improve performance when
working with xml/xsl engines which don't support the relevant attributes.
Include this change when backporting.

The kerberos RPC does not declare any restriction on
characters used in kerberos names, though
implementations MAY be more restrictive.
If the kerberos controller supports use non-conventional
principal names *and the kerberos admin chooses to use them*
this can confuse some of the parsing.
The obvious solution is for the enterprise admins to "not do that"
as a lot of things break, bits of hadoop included.
Harden the hadoop code slightly so at least we fail more gracefully,
so people can then get in touch with their sysadmin and tell them
to stop it.
This has triggered an OOM in a process which was churning through s3a fs
instances; the increased memory footprint of IOStatistics amplified what
must have been a long-standing issue with FS instances being created
and not closed()
* Makes sure instrumentation is closed when the FS is closed.
* Uses a weak reference from metrics to instrumentation, so even
if the FS wasn't closed (see HADOOP-18478), this back reference
would not cause the S3AInstrumentation reference to be retained.
* If S3AFileSystem is configured to log at TRACE it will log the
calling stack of initialize(), so help identify where the
instance is being created. This should help track down
the cause of instance leakage.

This addresses HADOOP-18521, "ABFS ReadBufferManager buffer sharing
across concurrent HTTP requests" by not trying to cancel
in progress reads.
It supercedes HADOOP-18528, which disables the prefetching.
If that patch is applied *after* this one, prefetching
will be disabled.
As well as changing the default value in the code,
core-default.xml is updated to set
fs.azure.enable.readahead = true
As a result, if Configuration.get("fs.azure.enable.readahead")
returns a non-null value, then it can be inferred that
it was set in or core-default.xml (the fix is present)
or in core-site.xml (someone asked for it).

* Exactly 1 sending thread per an RPC connection.
* If the calling thread is interrupted before the socket write, it will be skipped instead of sending it anyways.
* If the calling thread is interrupted during the socket write, the write will finish.
* RPC requests will be written to the socket in the order received.
* Sending thread is only started by the receiving thread.
* The sending thread periodically checks the shouldCloseConnection flag.
Disables block prefetching on ABFS InputStreams, by setting
fs.azure.enable.readahead to false in core-default.xml and
the matching java constant.
This prevents
HADOOP-18521. ABFS ReadBufferManager buffer sharing across concurrent HTTP requests.
Once a fix for that is committed, this change can be reverted.

Updates okhttp3 and okio so their transitive dependency on Kotlin
stdlib is free from recent CVEs.
okhttp3:okhttp => 4.10.0
okio:okio => 3.2.0
kotlin stdlib => 1.6.20
kotlin CVEs fixed:
CVE-2022-24329
CVE-2020-29582

Move construction of XML parsers in YARN
modules to using the locked-down parser factory
of HADOOP-18469.
One exception: GpuDeviceInformationParser still supports DTD resolution;
all other features are disabled.

Add to XMLUtils a set of methods to create secure XML Parsers/transformers, locking down DTD, schema, XXE exposure.
Use these wherever XML parsers are created.

Make S3APrefetchingInputStream.seek() completely lazy. Calls to seek() will not affect the current buffer nor interfere with prefetching, until read() is called.
This change allows various usage patterns to benefit from prefetching, e.g. when calling readFully(position, buffer) in a loop for contiguous positions the intermediate internal calls to seek() will be noops and prefetching will have the same performance as in a sequential read.

part of HADOOP-18103.
Also introducing a config fs.s3a.vectored.active.ranged.reads
to configure the maximum number of number of range reads a
single input stream can have active (downloading, or queued)
to the central FileSystem instance's pool of queued operations.
This stops a single stream overloading the shared thread pool.
