Overhaul ClassLoaderWeavingAdaptor to use statically initialised Unsafe
instances and method handles pointing to their 'defineClass' methods.
Those now work universally on JDKs 8-21. In older JDKs, the method used
to be in sun.misc.Unsafe, in more recent ones on jdk.internal.misc.Unsafe.
It is challenging to fetch instances, especially as reflection
protection and module boundaries have been increased in the JDK
progressively. But finally, a solution was adapted from Byte Buddy (BB).
Kudos to BB author Rafael Winterhalter. The previous solution to use
ClassLoader::defineClass and require '--add-opens' is no longer
necessary for the first time since it became necessary in AspectJ 1.9.7
with Java 16 support.
Add org.ow2.asm:asm-common as a dependency everywhere org.ow2.asm:asm
was used before. Maybe that is too many places, but no worse than before.
Add missing dependency on loadtime to aspectjweaver. This kept a build
like "mvn install -am -pl aspectjweaver" from picking up changed
loadtime classes.
Fixes #117.

Currently, the situation looks more like a Java 21 maintenance release
than directly a Java 22 release.

Document build profiles and properties in docs/developer/BUILD.md
In doing so, I also noticed a few things in need of improvement. So,
documenting the build also drive those enhancements, such as
- the new 'fast-build' profile skipping test compilation and execution
as well as documentation generation,
- an option to skip generating source assemblies,
- to skip unzipping source assemblies if javadoc generation for them
is to be skipped too,
- activating the 'create-docs' profile by property which is
true by default instead of using 'activeByDefault=true', because the
latter does not work reliably if other profiles are activated
manually according to a Maven bug that was closed as "won't fix",
- no longer generating separate javadocs for the 'runtime' module,
because that module is not deployed and the main artifacts recreate
Javadocs from scratch for all of their constituent sources anyway.

This is a bugfix release, reverting the essential parts of commit
f70aeb5e, because it causes AspectJ Maven integration tests using
javadoc to fail on JDK 8.

Fix Javadoc generation by also unpacking relocated ASM sources
Suddenly, for AspectJ Weaver + Tools Javadoc generation started to fail.
This might be due to switching from ASM-renamed to dynamically shaded
ASM. Either way, the Javadoc tool complains about the missing source
files. Therefore, we also unpack them from the source uber JAR now via
TrueZIP before generating Javadoc.

Upgrade Maven Shade Plugin to 3.2.4.MSHADE-252-391
Unfortunately, the issues fixed in the aspectj.dev fork are still not
available upstream (MSHADE-252 is merged, but unreleased, MSHADE-391 is
in review).
Also use Maven Javadoc Plugin version from parent POM.

Before, we used 1.9.7.BUILD-SNAPSHOT, which according to Andy Clement
was originally an intent across a group of Spring projects he was
involved in, to ensure that SNAPSHOTS were sorted alphabetically ahead
of MILESTONEs and ahead of RCs.

This involves replacing references in weaver application code as well as
a few tests.
In order to make AspectJ weaver + tools contain a relocated ASM version,
I added a Maven Shade relocation step after Maven Assembly created the
uber JARs. Relocation works for both binaries and sources and also
encompasses Class::forName calls like in class AsmDetector.

Other than Maven Deploy, Nexus Staging plugin cannot just be added to
the 'build/plugins' section of the parent POM once and (de-)activated
with a simple property like 'maven.deploy.skip' on a per-module basis.
See also https://issues.sonatype.org/browse/OSSRH-68966. Consequently,
we do not add it to the parent but separately to each module meant to be
published.

Create javadoc for all public artifacts, fix dependencies
Sonatype OSSRH repository rules require source and javadoc JARs in
order to create staging repositories for releases to be promoted to
Maven Central. So I added build steps to unzip the source JARs and then
create Javadocs for them.
FIXME: This configuration works with JDK 16, but throws errors on other
JDK versions, e.g. 14. It looks as if the Maven Javadoc plugin does not
do a particularly good job applying the plugin settings in a way making
it work with different JDK javadoc tool versions. I am saying that,
because when using the tool directly on the console, it works with basic
settings and the correct classpath.
In order to enable creating uber JARs via Maven Shade in the future, I
also added missing dependencies. Maven Assembly descriptors just assume
that all the necessary class files and sources already exist where it
copies them from. But several of the dependency modules were not
explicitly listed as such by the uber JAR modules. I fixed that.

Add information required by Maven Central to public artifact POMs
This is another step away from manual deployment towards Maven-triggered
deployment for both releases and snapshots. The 5 main POMs (matcher,
runtime, weaver, tools, installer) now contain information required by
Sonatype for Maven Central deployments according to:
https://central.sonatype.org/publish/requirements/
TODO:
- Add corresponding 'distributionManagement' section and necessary
release plugins for Sonatype OSS repositories to parent POM.
- Enable Maven to also use Install plugin in order to automatically
set release versions, commit to Git and tag releases, then upgrade
to a new snapshot afterwards.
- Make sure that Flatten Maven plugin does not strip off the required
tags we just added to the POMs. It looks as if the chosen
flattenMode=oss already retains the exact tags we need, only
slightly reformatting (hence "uglifying") the POM. But an ugly POM
does not block Maven Central deployments, as long as it is complete.
So it looks as if this to-do item is already done.
