Log message:
  Changes to improve sharing of display lists between contexts.
  
  - Keep track of a "shareCtx" associated with each context, so that
    when we replicate contexts we can also replicate their shared contexts
  
  - Attach a display list manager to every context (instead of attaching
    one to the entire SPU).  Contexts that share display lists will share
    the same display list manager; contexts that do not will have their
    own, independent display list managers.  This will allow contexts
    that have different display list contents to replicate those contents
    correctly when a new viewer attaches.
  
  - Maintain a list of context IDs in their order of creation.  When we
    replicate contexts, they have to be replicated in order, to guarantee
    that display list sharing occurs correctly.  For example, assume context A
    is created, then context B is created that shares display lists with
    context A.  If, during replication, context B is created first, it will
    attempt to share display lists with a nonexistent context, which will
    fail.  Then when context A is created next, the two contexts will
    not share display lists.
  
    By recreating them in order, sharing works as expected.
