Fix imports for the new version of trollius, which changed its package name.
Small security improvements to xsrf tokens; add tests.

Use os.urandom(16) instead of uuid.uuid4(), to reclaim a few bits of
entropy.  Use _time_independent_equals for comparison.

ioloop.py: use itertools.count() as tiebreaker to preserve FIFO in case of tie

Current implementation does not function as a FIFO.  When adding multiple
timeouts with the same deadline, order is currently consistently mangled in the
event of a garbage collect.

As suggested by Ben Darnell at
https://groups.google.com/forum/#!topic/python-tornado/w8aKm6ZabUQ/discussion,
we need to add a sequence number to the Timeout class to serve as tiebreaker.
This code uses the model suggested by
https://docs.python.org/2/library/heapq.html#priority-queue-implementation-notes,
which uses itertools.count() to serve as our counter.
