#65124: Simple fixes shall be done in simple way

Javadoc tweaks, imports.

Incrementing spec versions in the trunk.
Wrote script to do it semiautomatically - no more repetitive strain injury.
Note to self or next victim: next time do a clean build *before* branching
and grep for warnings mentioning 'spec.version.base' and consider fixing some.

Code cleanup of test cases in standard modules. By no means complete, just what I got around to.
1. suite() methods that just included the tests introspected in the class. This is the default anyway.
2. main() methods that didn't do anything special. The Ant harness should handle this instead.
3. No-op overrides of setUp or tearDown - empty or only called super.
4. tearDown overrides which only nulled out vars which setUp would always initialize anyway.
5. Old or missing copyright notices.
6. Unnecessary unimported FQNs and import list cleanups.
7. Obsolete or pointless comments left behind by some wizard.
8. Empty Javadoc comments. (Why do people write these?!)
A disturbing number of test cases were not compilable to begin with and still won't be.
serverplugins/sun/appsrv81/test in particular is in poor condition.
Make sure xtest/instance/master-config.xml#unit-nb lists your module if you care about its tests!

removed useless NOI18N

Javadoc note.

#62101: Fixing broken links

#63238: if findHelp results in a CNFE, it's probably not something anyone really cares to see.

Comment only.

#62680: make test pass on Windows too.
