    fix #4001: fix_imports didn't check for __init__.py before converting to relative imports

    Add an alternative iterative pattern matching system that, while slower, correctly parses files that cause the faster recursive pattern matcher to fail with a recursion error. lib2to3 falls back to the iterative matcher if the recursive one fails.

    Fixes http://bugs.python.org/issue2532. Thanks to Nick Edds.
