Tyler Goodlet a9985c0c01 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 db15162f04 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 9d4dba23a6 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.

Tyler Goodlet 19825ba284 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 420cd8de13 Use context for remote debugger locking
A context is the natural fit (vs. a receive stream) for locking the root
proc's tty usage via it's `.started()` sync point. Simplify the
`_breakpoin()` routine to be a simple async func instead of all this
"returning a coroutine" stuff from before we decided that
`tractor.breakpoint()` must be async. Use `runtime` level for locking
logging making it easier to trace.

Tyler Goodlet 15fa777ddf Add initial bi-directional streaming
This mostly adds the api described in
https://github.com/goodboy/tractor/issues/53#issuecomment-806258798

The first draft summary:
- formalize bidir steaming using the `trio.Channel` style interface
  which we derive as a `MsgStream` type.
- add `Portal.open_context()` which provides a `trio.Nursery.start()`
  remote task invocation style for setting up and tearing down tasks
  contexts in remote actors.
- add a distinct `'started'` message to the ipc protocol to facilitate
  `Context.start()` with a first return value.
- for our `ReceiveMsgStream` type, don't cancel the remote task in
  `.aclose()`; this is now done explicitly by the surrounding `Context`
   usage: `Context.cancel()`.
- streams in either direction still use a `'yield'` message keeping the
  proto mostly symmetric without having to worry about which side is the
  caller / portal opener.
- subtlety: only allow sending a `'stop'` message during a 2-way
  streaming context from `ReceiveStream.aclose()`, detailed comment
  with explanation is included.

Tyler Goodlet 607c48f1ac Distinctly separate and harden mp spawning
It's clear now that special attention is needed to handle the case where
a spawned `multiprocessing` proc is started but then the parent is
cancelled before the child can connect back; in this case we need to be
sure to kill the near-zombie child asap. This may end up being the
solution to other resiliency issues seen around mp with nested process
trees too. More testing is needed to be sure.
