`anon` compiler regression

anon type only works for directly defined containers.
Also it probably should work with other types besides container/bitfield (like ({ a, ...null, b })).

Protocol definition to reproduce:

{
  "types": {
    "void": "native",
    "container": "native"
  },
  "sqirrel": {
    "types": {
      "closure": [
        "container",
        [
          {
            "name": "main",
            "type": "void"
          }
        ]
      ],
      "script": [
        "container",
        [
          {
            "anon": true,
            "type": "closure"
          }
        ]
      ]
    }
  }
}

Start with the failing protocol definition and the stack-trace entry points in compiler-structures.js, compiler.js, and protodef.js. Reproduce the Cannot inline anonymous type: closure error, then trace how anon handles indirectly defined containers. Done means the reproduced case works and the intended support for other types is clarified or covered.
