Enhance and generalize AWT Threading* implementation; Minor changes ..

Threading*:
  - add invoke(..) generalizing the Therading decision

GLCanvas:
  - remove 'manual' Threading decision, simply call Threading.invoke(..)
  - use anonymous Runnable instances
  - remove drawable lock, drawable is volatile instead

GLJPanel:
  - remove 'manual' Threading decision, simply call Threading.invoke(..)
  - use anonymous Runnable instances
  - DEBUG: Use getThreadName() prefix

GLContextImpl:
  - Remove GLWorkerThread idle command on makeCurrent(),
    no holding of context in worker thread while idle.
  - DEBUG: Use getThreadName() prefix

X11GLXContext:
  - DEBUG: Use getThreadName() prefix

TODO: Validate whether it's OK for GLCanvas and GLJPanel to set Threading.Mode.MT as the default mode!
