  Log:
  - removed Win32-only IOErrorType.ComError
  - added IOErrorType.(DynIOError Dynamic.Dynamic)
  
    Propagating dynamically-typed exceptions as Exception.DynException
    isn't always the right thing to do
    [ why? You cannot catch them with IO.catch & you don't get the
      'infrastructure' that IOError offers, so you're forced to
      reinvent that wheel for each dynamic exception.
    ]
  - removed IOExts.isComError  :: IOError -> Bool
  - added IOExts.isDynIOError  :: IOError -> Bool
  - added IOExts.getDynIOError :: IOError -> Dynamic.Dynamic
  - documented IOExts changes.
