Inline adoc when include has no additional value (#1940)
Inline adoc files when they are included exactly once.

Also fix language tags because this inlining gives us better information
on what language the code is written in.

== Why is this an issue?
The purpose of synchronization is to ensure that only one thread executes a given block of code at a time. There's no real problem with marking ``++writeObject++`` ``++synchronized++``, but it's highly suspicious if this serialization-related method is the only ``++synchronized++`` code in a ``++class++``.
=== Noncompliant code example
[source,java]
----
public class RubberBall {
private Color color;
private int diameter;
public RubberBall(Color color, int diameter) {
// ...
}
public void bounce(float angle, float velocity) {
// ...
}
private synchronized void writeObject(ObjectOutputStream stream) throws IOException { // Noncompliant
// ...
}
}
