Tyler Goodlet d182fa7036 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 7df6fe54f0 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 88c449ca2e 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 5b65dd8871 Add streaming decode support for `msgspec` 
Add a `tractor._ipc.MsgspecStream` type which can be swapped in for
`msgspec` serialization transparently. A small msg-length-prefix framing
is implemented as part of the type and we use
`tricycle.BufferedReceieveStream` to handle buffering logic for the
underlying transport.

Notes:
- had to force cast a few more list  -> tuple spots due to no native
  `tuple`decode-by-default in `msgspec`: https://github.com/jcrist/msgspec/issues/30
- the framing can be understood by this protobuf walkthrough:
  https://eli.thegreenplace.net/2011/08/02/length-prefix-framing-for-protocol-buffers
- `tricycle` becomes a new dependency

Tyler Goodlet c83b9cc940 Try out `msgspec` in our msgpack stream channel 
Can only really use an encoder currently since there is no streaming api
in `msgspec` as of currently. See jcrist/msgspec#27.

Not sure if any encoding speedups are currently noticeable especially
without any validation going on yet XD.

First experiments toward #196

Tyler Goodlet 48017e52ab 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 00c06a00ae Explicitly formalize context/streaming teardown 
Add clear teardown semantics for `Context` such that the remote side
cancellation propagation happens only on error or if client code
explicitly requests it (either by exit flag to `Portal.open_context()`
or by manually calling `Context.cancel()`).  Add `Context.result()`
to wait on and capture the final result from a remote context function;
any lingering msg sequence will be consumed/discarded.

Changes in order to make this possible:
- pass the runtime msg loop's feeder receive channel in to the context
  on the calling (portal opening) side such that a final 'return' msg
  can be waited upon using `Context.result()` which delivers the final
  return value from the callee side `@tractor.context` async function.
- always await a final result from the target context function in
  `Portal.open_context()`'s `__aexit__()` if the context has not
  been (requested to be) cancelled by client code on block exit.
- add an internal `Context._cancel_called` for context "cancel
  requested" tracking (much like `trio`'s cancel scope).
- allow flagging a stream as terminated using an internal
  `._eoc` flag which will mark the stream as stopped for iteration.
- drop `StopAsyncIteration` catching in `.receive()`; it does
  nothing.

Tyler Goodlet f0ceb9a811 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.
