- fix some spelling, add documentation
- add NS_NewArray(), including one that takes an existing nsCOMArray<T>
- implement copy constructor for nsCOMArray_base, so that NS_NewArray can work
not part of build
- tri-license with MPL, not NPL
- be consistent with policy on null in the array (it is allowed)
- move Clear() into implementation file, and hide static callback there too
- make sure to AddRef() on the way out of nsArray::IndexOf()
- handle failure of ReplaceElementAt more gracefully
