GLContext*/GLDrawableHelper: Fix consistency of recursive makeCurrent()/release()/destroy() calls
Utilizing volatile and lock.tryLock(0) for lockConsiderFailFast(),
reducing redundant synchronization and using RecursiveLock implicit sync.
GLContext 'early-out' is the case where the thread already holds the
context, ie. context is already current and the native makeCurrent is skipped.
makeCurrent()'s 'early-out' w/o incr. the recursive lock of GLContext
and it's NativeSurface could lead to asymetry in lock/unlock count
with release()/destroy() calls. The 1st release actually released the
native ctx already.
Properly utilize recursive lock/unlock in all cases and impl. 'early-out' after locking.
Following the above in GLDrawableHelper.invokeGL()'s 'early-out' case as well,
ie calling makeCurrent()/release() symmetrical.
Introduce GLDrawableHelper.disposeGL(), which issues dispose on all GLEventListeners
within a current context and issued context destruction directly.
This simplifies GLAutodrawable's destroy/dispose calls and ensures
that the above sequence of events happens atomically (lock is being hold until destruction).
Enable context switch tracing
If property 'jogl.debug.GLContext.TraceSwitch' is defined, trace context switch.
