Tyler Goodlet ee87cf0e29 Add a debug-mode-breakpoint-causes-hang case! 
Only found this by luck more or less (while working on something in
a client project) and it turns out we can actually get to (yet another)
hang state where SIGINT will be ignored by the root actor on teardown..

I've added all the necessary logic flags to reproduce. We obviously need
a follow up bug issue and a test suite to replicate!

It appears as though the following are required based on very light
tinkering:
- infected asyncio mode active
- debug mode active
- the `trio` context must breakpoint *before* `.started()`-ing
- the `asyncio` must **not** error

Tyler Goodlet 79622bbeea Restore `breakpoint()` hook after runtime exits 
Previously we were leaking our (pdb++) override into the Python runtime
which would always result in a runtime error whenever `breakpoint()` is
called outside our runtime; after exit of the root actor . This
explicitly restores any previous hook override (detected during startup)
or deletes the hook and restores the environment if none existed prior.

Also adds a new WIP debugging example script to ensure breakpointing
works as normal after runtime close; this will be added to the test
suite.

Tyler Goodlet 6c35ba2cb6 Add IPC breakage on both parent and child side 
With the new fancy `_pytest.pathlib.import_path()` we can do real
parametrization of the example-script-module code and thus configure
whether the child, parent, or both silently break the IPC connection.

Parametrize the test for all the above mentioned cases as well as the
case where the IPC never breaks but we still simulate the user hammering
ctl-c / SIGINT to terminate the actor tree. Adjust expected errors based
on each case and heavily document each of these.

Tyler Goodlet 36a83cb306 Refine example to drop IPC mid-stream 
Use a task nursery in the subactor to spawn tasks which cancel the IPC
channel mid stream to simulate the most concurrent case we're likely to
see. Make `main()` accept a `debug_mode: bool` for parametrization. Fill
out detailed comments/docs on this example.

Tyler Goodlet 21dccb2e79 A `.open_context()` example that causes a hang! 
Finally! I think this may be the root issue we've been seeing in
production in a client project.

No idea yet why this is happening but the fault-causing sequence seems
to be:
- `.open_context()` in a child actor
- enter the debugger via `tractor.breakpoint()`
- continue from that entry via `c` command in REPL
- raise an error just after inside the context task's body

Looking at logging it appears as though the child thinks it has the tty
but no input is accepted on the REPL and a further `ctrl-c` results in
some teardown but also a further hang where both parent and child become
unresponsive..

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.
