Log Message:
* Resubmitting 4795 with an additional fix for unresolved namespaces
  that come from variables.  For example:
    var ns:Namespace = new Namespace("blah");
    foo.ns::bar();
  This is part of the fix for SDK-17798.  It allows
  DataBindingFirstPassEvaluator to find type information for
  namespaceBT2 in:
  But this isn't a complete fix, because I couldn't figure out how to
  allow the PropertyWatcher for "test_namespace::namespaceBT2" to
  access the property.  The solution will probably be to provide the
  open namespaces to the PropertyWatcher, but I haven't figured out
  how to do this yet.
tests Passed: checkintests, performance testsuite
Needs QA: YES

Bug fixes: SDK-19047, SDK-17798 (partial fix)
API Change: NO

Code-level description of changes:
  semantics/FlowAnalyzer.java
    See notes for revision 4795.
  util/Context.java
    Modified processUnresolvedNamespaces() to report an error if we
    can't find a Slot for the namespace, but no longer report an error
    if we find a Slot without a Value.  This happens when the
    namespace is defined in a variable.  ConstantEvaluator will not
    have run yet, so the Slot for the namespace will not have a Value.
    We just silently punt in this case.  The VM will report an error
    at runtime if the namespace can't be resolved.  Unfortunately,
    data binding won't be able to track down change events in this
    case, though.
