Previously it was possible for a thread to call Waker.defer() after
Broker has torns its Waker down, and the underlying file descriptor
reallocated by the OS to some other component.
This manifested as latches of a subsequent test invocation receiving the
waker byte (' ') rather than their expected byte '\x7f'.
This doesn't fix the problem, it just significantly reduces the chance
of it occurring. In future Side.write()/read()/close() must be
synchronized with a lock.
Previously the problem could be reliably triggered with:
while :; do
python tests/call_function_test.py -vf CallFunctionTest.{test_aborted_on_local_broker_shutdown,test_aborted_on_local_context_disconnect}
done

The whitelist check must happen /after/ the other checks, otherwise we
unconditionally retunr self for crap like 'ansible.module_utils.json'.
looks like this was just as broken on 2.x, and suddenly we're
finding a bunch more legit Django deps. It seems anywhere
absolute_import appeared in 2.x, we skipped some imports.
The old hack on the master side we had is broken for some reason on 3.x.
Instead tweak the client to be more selective: if a request is for a
module within a package, the package must be loaded (in sys.modules),
and its __loader__ must be us. Previously if the module didn't exist in
sys.modules, we'd still try to fetch from the master, which doesn't
appear to ever make sense.
* ansible: use unicode_literals everywhere since it only needs to be
compatible back to 2.6.
* compat/collections.py: delete this entirely and rip out the parts of
functools that require it.
* Introduce serializable Kwargs dict subclass that translates keys to
Unicode on instantiation.
* enable_debug_logging() must set _v/_vv globals.
* cStringIO does not exist in 3.x.
* Treat IOLogger and LogForwarder input as latin-1.
* Avoid ResourceWarnings in first stage by explicitly closing fps.
* Fix preamble_size.py syntax errors.
This appears to be harmless, except for Python 2.6 on Linux/Travis,
where for some reason (some stdlib change?) simply opening the TTY is
insufficient.
