  Introduce a user macro named $(externalsDir), which should point to the root directory of where all the external sources should live.  Developers can change this value if their external sources live elsewhere.  The default of '..\..' matches the current status quo.

  Fixed the semantic of timeout for socket.create_connection and
  all the upper level libraries that use it, including urllib2.
  Added and fixed some tests, and changed docs correspondingly.
  Thanks to John J Lee for the patch and the pusing, :)
