Tyler Goodlet 4de75c3a9d Test cancel via api and keyboard interrupt
An initial attempt to discover an issue with trio-run-inprocess.
This is a good test to have regardless.

Tyler Goodlet 8e32199509 Get entry points reorg without asyncio compat
This is an edit to factor out changes needed for the `asyncio` in guest mode
integration (which currently isn't tested well) so that later more pertinent
changes (which are tested well) can be rebased off of this branch and
merged into mainline sooner. The *infect_asyncio* branch will need to be
rebased onto this branch as well before merge to mainline.

Tyler Goodlet 8054bc7c70 Support "infected asyncio" actors
This is an initial solution for #120.

Allow spawning `asyncio` based actors which run `trio` in guest
mode. This enables spawning `tractor` actors on top of the `asyncio`
event loop whilst still leveraging the SC focused internal actor
supervision machinery. Add a `tractor.to_syncio.run()` api to allow
spawning tasks on the `asyncio` loop from an embedded (remote) `trio`
task and return or stream results all the way back through the `tractor`
IPC system using a very similar api to portals.

One outstanding problem is getting SC around calls to
`asyncio.create_task()`. Currently a task that crashes isn't able to
easily relay the error to the embedded `trio` task without us fully
enforcing the portals based message protocol (which seems superfluous
given the error ref is in process). Further experiments using `anyio`
task groups may alleviate this.

Tyler Goodlet 7880934505 Add tests for all docs examples
Parametrize our docs example test to include all (now fixed) examples
from the `READ.rst`. The examples themselves have been fixed/corrected
to run but they haven't yet been updated in the actual docs. Once #99
lands these example scripts will be directly included in our
documentation so there will be no possibility of presenting incorrect
examples to our users! This technically fixes #108 even though the new
example aren't going to be included directly in our docs until #99
lands.

Tyler Goodlet c6f3ab5ae2 Initial examples testing attempt
A per #98 we need tests for examples from the docs as they would be run
by a user copy and pasting the code. This adds a small system for loading
examples from an "examples/" directory and executing them in
a subprocess while checking the output. We can use this to also verify
end-to-end expected logging output on std streams (ex. logging on
stderr).

To expand this further we can parameterize the test list using the
contents of the examples directory instead of hardcoding the script
names as I've done here initially.

Also, fix up the current readme examples to have the required/proper `if
__name__ == '__main__'` script guard.

Tyler Goodlet d8daa57a33 Add script "guards" to docs examples
This was originally bundled in #102 but the windows CI there has blocked
that from landing quickly. These examples need to be fixed stat since
I've had at least a couple people notice it now when first trying out
the project.

Tyler Goodlet d64508e1a6 Add more detailed docs around nursery logic
The logic in the `ActorNursery` block is critical to cancellation
semantics and in particular, understanding how supervisor strategies are
invoked. Stick in a bunch of explanatory comments to clear up these
details and also prepare to introduce more supervisor strats besides
the current one-cancels-all approach.

Tyler Goodlet 6348121d23 Do __main__ fixups like ``mulitprocessing does``
Instead of hackery trying to map modules manually from the filesystem
let Python do all the work by simply copying what ``multiprocessing``
does to "fixup the __main__ module" in spawned subprocesses. The new
private module ``_mp_fixup_main.py`` is simply cherry picked code from
``multiprocessing.spawn`` which does just that. We only need these
"fixups" when using a backend other then ``multiprocessing``; for
now just when using ``trio_run_in_process``.

Tyler Goodlet 2a4307975d Fix that thing where the first example in your docs is supposed to work
Thanks to @salotz for pointing out that the first example in the docs
was broken. Though it's somewhat embarrassing this might also explain
the problem in #79 and certain issues in #59...

The solution here is to import the target RPC module using the its
unique basename and absolute filepath in the sub-actor that requires it.
Special handling for `__main__` and `__mp_main__` is needed since the
spawned subprocess will have no knowledge about these parent-
-state-specific module variables. Solution: map the modules name to the
respective module file basename in the child process since the module
variables will of course have different values in children.
