Tyler Goodlet c3484f83f0 Wow, fix all the broken async func invoking code.. 
Clearly this wasn't developed against a task that spawned just an async
func in `asyncio`.. Fix all that and remove a bunch of unnecessary func
layers. Add provisional support for the target receiving the `to_trio`
and `from_trio` channels and for the @tractor.stream marker.

Tyler Goodlet e77f5dcdfa Move asyncio guest mode entrypoint to `to_asyncio` 
The function is useful if you want to run the "main process" under
`asyncio`. Until `trio` core wraps this better we'll keep our own copy
in the interim (there's a new "inside-out-guest" mode almost on
mainline so hang tight).

Tyler Goodlet 4df633f30e Propagate any spawned `asyncio` task error upwards 
This should mostly maintain top level SC principles for any task spawned
using `tractor.to_asyncio.run()`. When the `asyncio` task completes make
sure to cancel the pertaining `trio` cancel scope and raise any error
that may have resulted.

Resolves #120

Tyler Goodlet f2a1064b17 Adjust debug tests to accomodate no more root clobbering 
We may get multiple re-entries to debugger by `bp_forever` sub-actor
now since the root will incrementally try to cancel it only when the tty
lock is not held.

Tyler Goodlet 4800dfe12e Solve the root-cancels-child-in-tty-lock race 
Finally this makes a cancelled root actor nursery not clobber child
tasks which request and lock the root's tty for the debugger repl.

Using an edge triggered event which is set after all fifo-lock-queued
tasks are complete, we can be sure that no lingering child tasks are
going to get interrupted during pdb use and tty lock acquisition.
Further, even if new tasks do queue up to get the lock, the root will
incrementally send cancel msgs to each sub-actor only once the tty is
not locked by a (set of) child request task(s). Add shielding around all
the critical sections where the child attempts to allocate the lock from
the root such that it won't be disrupted from cancel messages from the
root after the acquire lock transaction has started.

Tyler Goodlet 9f1f956902 Don't kill root's immediate children when in debug 
If the root calls `trio.Process.kill()` on immediate child proc teardown
when the child is using pdb, we can get stdstreams clobbering that
results in a pdb++ repl where the user can't see what's been typed. Not
killing such children on cancellation / error seems to resolve this
issue whilst still giving reliable termination. For now, code that
special path until a time it becomes a problem for ensuring zombie
reaps.

Tyler Goodlet 288e2b5db1 Set stream "end of channel" after shielded check! 
Another face palm that was causing serious issues for code that is using
the `.shielded` feature..

Add a bunch more detailed comments for all this subtlety and hopefully
get it right once and for all. Also aggregated the `trio` errors that
should trigger closure inside `.aclose()`, hopefully that's right too.

Tyler Goodlet 59c8f72952 Don't clobber msg loop mem chan on rx stream close 
Revert this change since it really is poking at internals and doesn't
make a lot of sense. If the context is going to be cancelled then the
msg loop will tear down the feed memory channel when ready, we don't
need to be clobbering it and confusing the runtime machinery lol.
