Tyler Goodlet ecced3d09a Allow choosing the spawn backend per test session 
Add a `--spawn-backend` option which can be set to one of {'mp',
'trio_run_in_process'} which will either run the test suite using the
`multiprocessing` or `trio-run-in-process` backend respectively.
Currently trying to run both in the same session can result in hangs
seemingly due to a lack of cleanup of forkservers / resource trackers
from `multiprocessing` which cause broken pipe errors on occasion (no
idea on the details).

For `test_cancellation.py::test_nested_multierrors`, use less nesting
when mp is used since it breaks if we push it too hard with the
whole recursive subprocess spawning thing...

Tyler Goodlet 783fe53b06 Don't mix trip with multiprocessing for now 
It seems that mixing the two backends in the test suite results in hangs
due to lingering forkservers and resource managers from
`multiprocessing`? Likely we'll need either 2 separate CI runs to work
or someway to be sure that these lingering servers are killed in between
tests.

Tyler Goodlet 915bf17a9a Add process tree depth control to nested multierror test 
Another step toward having a complete test for #89.
Subactor breadth still seems to cause the most havoc and is why I've
kept that value to just 2 for now.

Tyler Goodlet 2d4b6de4f4 Spawn even less suba-actors in Windows CI 
Seems like we've probably got some greater limitations
with Windows and "nested" spawned sub-processes...

Tyler Goodlet 6d9ac53bd5 Add nested multierror testing 
Add a test to verify that `trio.MultiError`s are properly propagated up
a simple actor nursery tree. We don't have any exception marshalling
between processes (yet) so we can't validate much more then a simple
2-depth tree. This satisfies the final bullet in #43.

Note I've limited the number of subactors per layer to around 5 since
any more then this seems to break the `multiprocessing` forkserver;
zombie subprocesses seem to be blocking teardown somehow...

Also add a single depth fast fail test just to verify that it's the
nested spawning that triggers this forkserver bug.

Tyler Goodlet d406383cd3 Add a preliminary nested subactor `MultiError` test 
This exemplifies the undefined behaviour in #88 and begins to test for
the last bullet in #43.

Tyler Goodlet 6dbb3f7ae6 Extend cancellation tests 
In an effort towards #43. This completes the first major bullet's worth of tests
described in that issue.

Tyler Goodlet faa1f373b5 Add subactor loglevel propagation test 
Can't seem to get the `capfd` fixture to capture subprocess logging to
stderr even though the console report shows the log message as being
captured? Skipping the test on the forkserver method for now.

Tyler Goodlet 41c202db68 Add a multi-task subscriber test 
In combination with `.aclose()`-ing the async gen instance returned from
`Portal.run()` this demonstrates the python bug:
https://bugs.python.org/issue32526

I've commented out the line that triggers the bug for now since this
case provides motivation for adding our own `trio.abc.ReceiveMemoryChannel`
implementation to be used instead of async gens directly (returned from
`Portal.run()`) since the latter is **not** task safe.
