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.

- Redundant copies of HTML files used in AspectJ installer, which
already exist as resource files in module 'build'
- Null-sized AspectJ library JARs which probably were used to trigger
certain build steps in the former Ant build
- BridgeVersion.java.txt, which has been replaced by a regular
org.aspectj.bridge.Version class which can dynamically determine
versions from a properties file instead of relying on them being
hard-coded into the template.

The former HTML file was moved up one directory level and converted to
asciidoc format. Therefore, include the ADOC file from the correct
location now.
Alternatively, we could have included the generated HTML from the
aj-build/dist/docs/doc directory, but that would have meant adding a
dependency to the 'docs' module to several other modules for this one
file. Actually, asciidoc has become a widely used and accepted format
for documentation and is human-readable by design. Therefore, it is OK
to include the ADOC file. The important thing is that the licence
information
- is contained in each published artifact,
- can be found easily,
- its content is human-readable.
All these requirements are still met with this change. Arguably, ADOC is
easier to read than HTML and does not even need a web browser.

Like the javadocs in aspectjrt and aspectjweaver (if the releas profile
is active), for docs also copy the docs in the package phase to the
aj-dist directory.

In the next step, the content, which is still HTML at this point, is
going to be converted.

If we ever decide to add Maven site docs to the AspectJ website, now we
can deploy them locally using 'mvn site:deploy' and publish them on a
web server or even incorporate them into the binary distribution in the
installer's belly.

Docs: Create separate CSS files, do not embed into HTML
TODO: There still is one set of CSS files per subdirectory due to the
way the docs directories are organised. It would be better to have them
just once. But to achieve that, the ADOC-to-HTML conversion would have
to be changed, e.g. using one central directory for images and
reorganisation of the overall directory structure and build options.

Rename doc generation profiles, making Asciidoctor the default
The Docbook etc. Ant task profile is now called 'create-docs-LEGACY' and

Using Asciidoctor Maven, we now produce PDFs (which are also linked to
from the main documentation index page) for
- Programming Guide,
- AspectJ 5 Developer's Notebook,
- Development Environment Guide,
- Problem Diagnosis Guide,
- AspectJ Design Overview.
Attention! PDF generation alone takes 3+ minutes, almost 4 minutes
including asciidoc to HTML conversion. Just deactivate the 'create-docs'
profile if you do not need docs during the build.
Closes #272.

Follow-up on previous rename-only commit. This time, the binaries are
real PNGs. The asciidoc and other references to them have also been
replaced. File figures_classes.png in the teaching materials also was
rotated by 90° to display it correctly.
Background: The Asciidoctor PDF back-end cannot handle GIFs directly
without an additional Ruby Gem. It is easier to only use PNGs and JPEGs.

The files are still GIFs for now. In the next steps after the rename,
they will be replaced by real PNGs.

- 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.

User relative paths for images instead.
In one case, we need to copy images from a subdirectory one level up,
because otherwise the images are only found in the included document,
but not in the single-page one including it from the subdirectory. In
all other cases, included ADOCs are located in the same directory as the
including document.
