LangUtil: remove methods like 'is11VMOrGreater', 'is1dot5VMOrGreater'
Replace them by a uniform method 'isVMGreaterOrEqual(double)', also
overloaded for int.
This gets rid of one 'AspectJ_JDK_Update' tag. One less place to check

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.

- AspectJ Browser (ajbrowser)
- Forte IDE integration
- JBuilder IDE integration
- Emacs integration
All this information was old and outdated. Ajbrowser was removed from
AspectJ a while ago. If the other tools even still exist, any possibly
existing AspectJ support is not part of AspectJ itself.

AjcTestCase: Make sure main methods can be called in Java 21
Since JDK 21, a public main method of a non-public (e.g. default-scoped)
class can no longer be invoked without making it accessible first.
Because many test sources contain multiple aspects and classes in one
file, this is a frequent use case.

This enables compiled source code to use ASM. This way, it is possible
to bootstrap tests needing specially prepared class files by
1. compiling an ASM-enabled byte code generator class,
2. running the generator, writing out class files,
3. using the generated class files in subsequent tests.
Until now, such classes always had to be checked into the ASM directly
or inside JARs. Now, this is no longer necessary.
The next commit will be the first example.

Further improve indentation of compilation results on the console
In CompilationResult.toString, no longer indent like this:
[warning 1] warning at
after() : execution(FooBar Blah.*()) {
^^^^^^
xxx FooBar [Xlint:invalidAbsoluteTypeName]
Instead, always just indent by 2 spaces, saving screen real estate:
[warning 1] warning at
after() : execution(FooBar Blah.*()) {
^^^^^^
xxx FooBar [Xlint:invalidAbsoluteTypeName]
Also further streamline/simplify the code a bit.

Fix indentation of compilation results on the console
Whenever warnings or errors were printed via CompilationResult.toString,
indirectly also using MessageUtil.renderMessage(IMessage, boolean),
messages containing context info such as code snippets with carets
marking erroneous tokens - see also the previous commit - prefixes like
"[warning 1] warning at " were printed right in front of the code
snippets. I.e., the carets marking erroneous tokens in the second line
were not indented like the first line with the code snippet, leading to
(simplified) output like:
[warning 1] warning at after() : execution(FooBar Blah.*()) {
^^^^^^
xxx FooBar [Xlint:invalidAbsoluteTypeName]
This was fixed to now correctly indent lines 2 to n according to line 1,
yielding the correct output:
[warning 1] warning at
after() : execution(FooBar Blah.*()) {
^^^^^^
xxx FooBar [Xlint:invalidAbsoluteTypeName]
Especially with longer, more complex context lines, this helps to
identify the erroneous section. BTW, for one-line messages, everything
of course looks like before.

At present, no tests are failing without those resources, but for good
measure, I added them anyway, because then the same path could in the
future also be used for stand-alone compilation tests which are not
triggered in-process via AJDT interface but, not unlike "full LTW"
test execution mode, in a separate JVM.

It was referring to a no longer existent weaver under
aj-build/dist/tools/lib/aspectjweaver.jar, which now has been replaced
by the new file lib/aspectj/lib/aspectjweaver.jar.
Several tests were broken, not finding the agent. But because those
tests make no assertions, nobody ever noticed. Only when I had to change
some LTW tests from in-process to full LTW mode (see next commit) due to
them now obviously calling some code paths which need '--add-opens', I
even noticed the problem.

Methods Integer.parseInt/Boolean.parseBoolean should be preferred over Integer.valueOf/Boolean.valueOf/ if final result is primitive.
They are generally faster and generate less garbage.
Rename DOM AST class TypePattern to AbstractTypePattern
Since JDT Core 3.27 (Java 17), there is a name clash, because the new
class org.eclipse.jdt.core.dom.TypePattern (JEP 406) gets relocated to
org.aspectj.org.eclipse.jdt.core.dom.TypePattern during shading.
Fortunately, this made tests like AjASTTest and AjAST5Test fail with
rather nasty errors like:
java.lang.VerifyError: Bad return type (...)
Type 'org/aspectj/org/eclipse/jdt/core/dom/TypePattern' (...) is not
assignable to 'org/aspectj/org/eclipse/jdt/core/dom/Pattern' (...)
TODO: Update AJDT references to the renamed class in the following
classes after refreshing the AspectJ sources:
- ExtraPackageReferenceFinder
- ExtraTypeReferenceFinder
This also means, that for Eclipse 2021-09 (4.21) we need a new AJDT
update site, because simply deploying to the 4.19 one would probably
lead to problems in the IDE.

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.

There are two styles to convert a collection to an array: either using a pre-sized array (like c.toArray(new String[c.size()])) or using an empty array (like c.toArray(new String[0]).
In older Java versions using pre-sized array was recommended, as the reflection call which is necessary to create an array of proper size was quite slow. However since late updates of OpenJDK 6 this call was intrinsified, making the performance of the empty array version the same and sometimes even better, compared to the pre-sized version. Also passing pre-sized array is dangerous for a concurrent or synchronized collection as a data race is possible between the size and toArray call which may result in extra nulls at the end of the array, if the collection was concurrently shrunk during the operation.
