Various fixes for cross test servers and clients

I hope it's the last time such a broad fix is needed on this.

• fix testBinary and testMultiException handler of c_glib server
• nodejs server testBinary handler was missing
• python and haskell lib names were incorrect in configure.ac (sorry about that)
• Enable dart in make cross
• ruby clients did not disconnect from the server
  Since many test servers use rudimentary TSimpleServer, it resulted in dead locks
• nodejs clients only half-closed (no more send) the connection.
  the same reason as the above, it resulted in hang.
  (The patch simply makes it exit with 0 in the end.)
• python server did not log anything to files
• nodejs client assumed that map and set orders were preserved
