Tyler Goodlet 568902a5a9 Add test for #265: "msg sent before stream opened" 
This always triggered the mentioned race condition.
We need to figure out the best approach to avoid this case.

Tyler Goodlet 121f7fd844 Draft test that shows a slow daemon cancellation 
Currently if the spawn task is waiting on a daemon actor it is likely in
`await proc.wait()`, however, if the actor nursery is subsequently
cancelled this checkpoint will be abandoned and the hard proc reaping
sequence will execute which results in a up to 3 second wait before
a "hard" system signal is sent to the child.  Ideally such
a cancelled-during-daemon-actor-wait condition is instead handled by
first trying to cancel the remote actor using `Portal.cancel_actor()` (a
"graceful" remote cancel request) which should (presuming normal runtime
operation) result in an immediate collection of the process after normal
actor (remotely triggered) runtime cancellation.

Tyler Goodlet f32ccd76aa Add `Portal.result()` is None test case 
This demonstrates a bug where if the remote `.run_in_actor()` task
returns `None` then multiple calls to `Portal.result()` will hang
forever...

Tyler Goodlet d0f5c7a5e2 Change to `gather_contexts()`, use event for graceful exit 
The api we've made here is actually closer to `asyncio.gather()` but
with opening async context managers instead of funcs. Use another event
to allow for graceful teardown of children on non-cancellation exits
and add a doc string.

Tyler Goodlet b14699d40b Adjust debugger tests to expect depth > 1 crashes 
With the new fixes to the trio spawner we can expect that both root
*and* depth > 1 nursery owning actors will now not clobber any children
that are in debug (either via breakpoint or through crashing). The tests
changed now include more checks which ensure the 2nd level parent-ish
actors also bubble up through into `pdb` and don't kill any of their
(crashed) children before they're done themselves debugging.

Tyler Goodlet 8d79d83ac2 Ensure kbi will cancel context block 
Follow up to previous commit: extend our simple context test set to
include cancellation via kbi in the parent as well as timeout logic and
testing of the parent opening a stream even though the target actor does
not.

Thanks again to https://github.com/adder46/wrath for discovering this
bug.

Tyler Goodlet c1727ce05e Add a test of both stream styles side-by-side 
Not sure we even have a test for this yet. The main issue discovered by
a user project (https://github.com/adder46/wrath) was that a kbi raised
inside a block like this (with both recv-only and send-recv streams)
would not cancel on the first ctrl-c sent from console and instead
SIGiNT had to be repeatedly sent as many times as there are subactors in
the first level tree. This test catches that as well as just verifies
the basic side-by-side functionality.

Tyler Goodlet 0d70e3081a Add laggy parent stream tests 
Add a couple more tests to check that a parent and sub-task stream can
be lagged and recovered (depending on who's slower). Factor some of the
test machinery into a new ctx mngr to make it all happen.

Tyler Goodlet af85d35685 Drop stream shielding; it was from a legacy design 
The whole origin was not having an explicit open/close semantic for
streams. We have that now so this internal mechanic isn't needed and
further our streams become more correct by having `.aclose()` be
independent of cancellation.
