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.
