ATI (fglrx) PBuffer/X11Display bug workaround/cleanup

    - See https://bugzilla.mozilla.org/show_bug.cgi?id=486277

    - Description:
        - To use PBuffer, a context must be current

        - X11Display cannot be switched while using the PBuffer
          [within one thread]. Hence we shall try harder to reuse
          _the_ user configured X11Display - whenever possible.
          This is actually a good thing, ie cleanup up our
          code again.

    - Changes to workaround/cleanup:
        - GLDrawableFactory* methods 'canCreate*()'
          are changed to 'canCreate*(AbstractGraphicsDevice)'
          to allow pipelining the X11Display.
          This reduces the overhead of using a local TLS X11Display.

    - WindowsDummyWGLDrawable cstr gets the GLProfile as a parameter now,
      this is done while adding X11DummyGLXDrawable - forseeing the
      usecase to query available GLProfiles at startup.

    - X11DummyGLXDrawable added, following the WindowsDummyWGLDrawable path
      to have a dummy GLContext current to fix the ATI bug.

NativeWindow X11:
    - Add XIOErrorHandler to identify the fatal failure
      of closing a Display (-> ATI bug).

Build:
    - Adding ant.jar and ant-junit.jar to the junit compile/run classpath
    -

Misc:
    - Fix: CreateDummyWindow(..) returns a HWND, not a HDC
    - mapToRealGLFunctionName: Added mapping for X11/GLX.
    - X11GLXGraphicsConfigurationFactory: Uncommented dead code 'createDefaultGraphicsConfigurationFBConfig'

Tests: Passed (Linux64bit: NVidia/ATI)

Todo: More tests on ATI, especially multithreading/X11Display usage.
