xd: dojo.addOnLoad issue if dojo.require() things as part of an addOnLoad listener

[James Burke]

There is an issue in xd loading if you do a dojo.require() as part of an addOnLoad listener, and after

dojo.addOnLoad(function(){
  dojo.require("dojo.crypto.MD5");
  dojo.addOnLoad(function(){
    //do something with dojo.crypto in here.
  });
});

The inner addOnLoad adds that listener to the same queue as the outer addonload queue, so it ends up executing before the dojo.require statements finish. Need to move the current queue off so that new dojo.addOnLoads happen after outstanding modules have loaded.

This might get a bit messy. If it looks like it will be too invasive, punt to 0.9.

Moving to 0.9.

(In [9970]) Fixes #2765: calling dojo.addOnLoad inside a dojo.addOnLoad after doing an xdomain dojo.require() should work now.
