Merged the int/long unification branch, by very crude means (sorry Thomas!).
I banged on the code (beyond what's in that branch) to make fewer tests fail;
the only tests that fail now are:
  test_descr -- can't pickle ints?!
  test_pickletools -- ???
  test_socket -- See python.org/sf/1619659
  test_sqlite -- ???
I'll deal with those later.
