Changes

Adapt to GlueGen's Lock ChangeSet: e4baba27507ce78e64a150ec6f69fb96f5721a34 ; Use generics

NEWT: Adapt to GlueGen's Lock ChangeSet, all java callbacks for native have 'defer' 1st argument

- Adapt to GlueGen's Lock ChangeSet: e4baba27507ce78e64a150ec6f69fb96f5721a34

- All java callbacks for native have 'defer' 1st argument.
  This allows enqueuing resulting events to the EDT if required,
  ie. the native thread may not be 'compatible' (MacOSX).

- MacOSX-Native: enqueue key/mouse events and defer:=true for all java callbacks
  Since we are comming from a 3rd-party thread (AWT/NSApp-MainThread)
  we shall not abuse it.

NEWT/Threading: MainThread / DefaultEDTUtil

- MainThread:
  This class no more implements EDTUtil!
  This class just provides a main-thread utility, forking of a main java class
  on another thread while being able to continue doing platform specific things
  on the main-thread. The latter is essential for eg. MacOSX, where we continue
  to run NSApp.run().

- DefaultEDTUtil:
  - if Lock.DEBUG validate that no recursive locks are being hold,
    where it shall not (EDT: startup and return from task execution)

  - If task execution's result wasn't waited for (checked),
    at least dump exeception's stack trace if i happened.

- MacDisplay: Just use DefaultEDTUtil

- MacWindow:
  - No more need of special locking -> removed nsViewLock, since:
    - using proper EDT
    - capability to run from multiple threads (native Java thread attachment)

tests: added some commented out 'wait for press enter' startups, reduce getCurrentScreenMode() loop to 100

GLContextImpl: Fix bug: Surface was not unlocked in case new context creation failed.
