Fix GLWindow/SWT-GLCanvas: set context synchronized ; Misc Changes

Fix GLWindow/SWT-GLCanvas: set context synchronized
  - GLWindow fix commit a0177c8a1048683e5d43f4712f8f9e37091d4e85.
    Removed explicit recursive surface lock requires
    recursive context locking, otherwise concurrent rendering fails.
    The implicit recursive surface lock within context makeCurrent()
    is applied after the context lock itself.

Misc Changes
  - Fix TestPBufferDeadlockAWT, which was not using the unique profile string reference
