Add Java 16 Linux matcher variant to HtmlDecorator
The Java 16 Javadoc generator has changed the HTML structure once again
even compared to Java 15. I adjusted the matching in HtmlDecorator and
also fixed CoverageTestCase. Most methods there I just made to work
quickly, but method 'testInnerAspect()' I actually refactored. Some
other methods could (probably should) be restructured in a similar
fashion, but for now I just wanted to understand what the test does and
see how much work it would be to refactor it. But finally, I just want
to get the GitHub CI build running on Java 16.
TODO: I did not check if the decorated HTML actually looks OK and am
unsure if the tests cover that sufficiently, I never reviewed the tests.
It would also be better to do regex matches instead of looking for
variants of fixed strings or maybe even to operate on a DOM. But I am
not in a mood to refactor that tonight.

Add diagnostic output to HtmlDecorator if AJ-Doc generation fails
HtmlDecorator.decorateHTMLFile is where after Java version upgrades
(i.e. also new Javadoc generator version) usually tests fail for the
first time during builds because strings no longer match as expected.
There now is this log message on stdOut: "Something unexpected went
wrong in HtmlDecorator. Here is the full file causing the problem:"
After that, a full HTML page is logged. I hope this helps me identify
the new error on GitHub Linux Java 16, because the same test works on
Windows and I have no idea how to remote-debug a GitHub CI build.

Keep only ASM 2.0 binary because it is still used in UnweavableTest
which uses an old ASM API, e.g. with a ClassWriter constructor which no
longer exists.
Also add JarJar 1.3 library because it is needed by an Ant task in
lib/asm/build.xml.

Reports on declarations of Collection variables made by using the collection class as the type, rather than an appropriate interface.

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.

Reports the copying of array contents to a collection where each element is added individually using a for loop. Such constructs may be replaced by a call to Collection.addAll(Arrays.asList()) or Collections.addAll().

'String.indexOf()' expression is replaceable with 'contains()'
Reports any String.indexOf() expressions which can be replaced with a call to the String.contains() method available in Java 5 and newer.

Reports for loops which iterate over collections or arrays, and can be replaced with an enhanced for loop (i.e. the foreach iteration syntax).

The version handling in LangUtil has been overhauled
to cope better with post 1.8 releases (JDK9 and JDK10 or 18.3
or whatever they call it). As part of this moved
to treating JDK9 as '9' rather than '1.9'. Also removed
duplicate version processing logic and had that defer to
the one place in LangUtil where we now deal with it.
Includes some generics tidyup in ajdoc. More ajdoc work
is necessary for Java10 because it removes the standard doclet
(old style). However trying to invoke the internal Javadoc
handler in Java10 is failing due to module visibility rules.
Fix 436653: conditional aspect activation plus various polish
Modified test expectation system so it is possible to say
the test cares about one particular message and the rest
do not matter (prefix message string with '*') - crude but
quick.
Polished many places to exploit generics
Upgraded all the tests to work on Java8 - some serious changes
regarding ajdoc on Java8. Hopefully it has stayed backwards
compatible with earlier JDK versions (e.g. if using AspectJ 1.8.3+
with a JDK less than 8) but no explicit testing done for this.
