    Use __DRIextension mechanism providing loader functionality to the driver.
    
    Instead of passing in a fixed struct, the loader now passes in a list
    of __DRIextension structs, to advertise the functionality it can provide
    to the driver.  Each extension is individually versioned and can be
    extended or phased out as the interface develops.

    Reduce the versioning madness required to create a DRI2 screen.
    
    Right now the DRI2 screen constructor takes 3 different versions:
    DRI, DDX and DRM.  This is mostly useless, though:
    
      DRI: The DRI driver doesn't actually care about the DRI protocol,
      it only talks to the loader, which in turn speaks DRI protocol.  Thus,
      the DRI protocol version is of not interest to the DRI driver, but it
      needs to know what functionality the loader provides.  At this point
      that's reflected in the __DRIinterfaceMethods struct and the
      internal_version integer.
    
      DDX: The DDX version number is essentially used to track extensions
      to the SAREA.  With DRI2 the SAREA consists of a number of versioned,
      self-describing blocks, so the DDX version is no longer interesting.
    
      DRM: We have the fd, lets just ask the kernel ourselves.

    intel: Set the lock flag early to avoid deadlock.
    
    Another regression from the intel_context.c merge.
