Bug 776 GLContext Sharing: Add copy-ctor to GLArrayData* w/ sliced Buffer; Refine GearsObject* GLArrayDataServer copying; GearsES*: Init VBO eagerly

Add copy-ctor to GLArrayData* w/ sliced Buffer to allow general sharing of VBO via these high-level types.

Refine GearsObject* GLArrayDataServer copying (commit bcfaa149b9803ce33c5a356cbcb45f7dfd3e4361):
  Utilize new GLArrayData* copy-ctor.

GearsES*: Init VBO eagerly, allowing VBO usage after init(..).
