Migrate Params class out to Java-Utils; update documentation

• Given its wider usefulness, the Params class has been migrated out to the Java-Utils library.
• README - Maven and Gradle integration examples have been updated to the latest versions and techniques.

More thread-related fixes

• DepthGauge: Replace thread-local counter with simple int (client will handle threading).
• CreateTest: Revise based on changes to DepthGauge, storing instances as thread-local.
• RunReflectiveCall:
  • methodHash: Incorporate thread hash code as the most significant factor.
  • fireBeforeInvocation: Replace flat has-notified tracking with call depth counting.
  • fireAfterInvocation: Replace flat has-notified tracking with call depth counting.

Refine Byte Buddy transform to eliminate muddled matching

junit-foundation-9.0.2

[maven-release-plugin] copy for tag junit-foundation-9.0.2

CORRECTION: Implement support for parallel execution

Re-publish... the last release didn't have the new code in it.

Implement support for parallel execution

• LifecycleHooks: Move CreateTest and Run classes to their own files; Complete overhaul of instrumentation code based on feedback from Rafael Winterhalter (creator of Byte Buddy).
• Run: Add explicit tracking of start/finish notifications; migrate attachment of registered RunListener service providers from RunChild; refactor to facilitate parallel execution.
• RunChild: Use factored methods of the Run class to attach run listeners, save thread runners and publish start/finish notifications; remove call depth tracking; revise to support interception for children of all types.
• RunReflectiveCall: Add explicit tracking of start/finish notifications; remove call depth tracking;
• Finished: New interceptor class to handle the finished method of RunnerScheduler objects.
• Move CreateTest and Run classes to their own files.
• Delete CreateTestClass and TestClassWatcher, which couldn't be universally supported and were of no discernible value.

Add interception of createTestClass() and run() methods for subtypes of the Suite class

• Add interception of createTestClass() and run() methods for subtypes of the Suite class

Prevent duplicate notifications; switch from scheduler wrapper to standard RunListener

• TestClassWatcher: Remove start/finish methods, which are essentially useless in parallel execution.
• Replace wrapper for runner scheduler (which isn't used by parallel runs) with standard RunListener.
• DepthGauge: New class to provide call depth counting for intercept methods.
• RunAnnouncer: New standard RunListener that produces enhanced RunWatcher notifications.
• Revise intercept methods, adding call depth counting and only sending notifications from top level.
• LifecycleHooks: For BlockJUnit4ClassRunner subtypes, add interception of createTestClass() and run() methods.
• Run: Switch runner stack from Stack to ArrayDeque; only notify about runner start/finish if current runner isn't top of stack; remove attachment of RunListener service providers.
• RunChild: Add attachment of RunListener service providers.
• AtomicTest: Switch constructor argument from FrameworkMethod to Description.
• Update README to document the current API.

Major revisions to replace TestClass context with test runner context

• MethodWatcher: Add runner argument to methods to provide context.
• RunWatcher: Revise methods to replace TestClass/method context with AtomicTest.
• Replace deprecated TestClassWatcher interface with TestClassWatcher2.
• UnitTestWatcher: Update bases on MethodWatcher revisions.
• Replace remaining uses of TestClass as context with runner object.
• Add code to track the active test runner of each thread.
• RunReflectiveCall: Only try to retrieve runner for "particle" methods.
• Configure unit tests to run in parallel.
• Update README to document current API.

Publish parameters as Optional Map instead of Object array

• Publish parameters as Optional Map instead of Object array.
• Revise artifact capture classes and unit tests to work with new parameter format.
• Add Param class to encapsulate key/value pairs
• Add static method to create Param object
• Add static method to create parameter map from a set of Param objects

Disambiguate target mapping methods

• Revise names of mapping methods that take a test class instance (a.k.a. - target) as their argument.
