Tyler Goodlet 2870828c34 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 6463aa1559 Add our own "transport closed" signal 
This change some super old (and bad) code from the project's very early
days. For some redic reason i must have thought masking `trio`'s
internal stream / transport errors and a TCP EOF as `StopAsyncIteration`
somehow a good idea. The reality is you probably
want to know the difference between an unexpected transport error
and a simple EOF lol. This begins to resolve that by adding our own
special `TransportClosed` error to signal the "graceful" termination of
a channel's underlying transport. Oh, and this builds on the `msgspec`
integration which helped shed light on the core issues here B)

Tyler Goodlet 39453e43e0 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 e6aecf2ae5 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.

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.
