Tyler Goodlet c0d8d4fd99 Support re-entrant calls to `get_arbiter()`
It gets called more then once when using `tractor.run()` and
then `find_actor()`. Also, allow passing in the log level to each
new spawned subactor.

Tyler Goodlet c062b01b7b Add an actor spawning test
Test that the actor nursery API and ``tractor.run`` entrypoint work when
the sub-actor's main task is all that is run (i.e. no rpc requests).

Tyler Goodlet 37eb8a8552 Fix actor nursery __exit__ handling
When an error is raised inside a nursery block (in the local actor)
cancel all spawned children and ensure the error is properly
unsuppressed.

Also,
- change `invoke_cmd` to `send_cmd` and expect the caller to use
  `result_from_q` (avoids implicit blocking for responses that might
  never arrive)
- `nursery.start()` the channel server block such that we wait for the
  underlying listener to spawn before making outbound connections
- cancel the channel server when an actor's main task completes
  (given that `outlive_main == False`)
- raise subactor errors directly in the local actors's msg loop
- enforce that `treat_as_gen` async functions respond with a caller id
  (`cid`) in each yield packet

Tyler Goodlet ef90d7f106 Add remote actor error handling and parent re-raising
Command requests are sent out and responses are handled in a "message
loop" where each command is associated with a "caller id" and multiple
cmds and results are multiplexed on the came inter-actor channel. When
a cmd result arrives it is pushed into a local queue and delivered to the
appropriate calling actor's task. Errors from a remote actor are always shipped
in an "error" packet back to their spawning-parent actor such that any error
in a subactor is always raised directly in the parent. Based on the
first response to a cmd (either a 'return' or 'yield' packet) the caller
side portal will retrieve values by wrapping the local response queue in
either of an async function or generator as appropriate.

Tyler Goodlet 58f0182d8f Add a very rough, minimal actor model system
I'm calling it `tractor` (as in trio-actor) for now.
Lots of work to do still as per the many comments!

- don't allow re-entrant `Channel.connect()` calls
- Make `Channel` an async iterable

Tyler Goodlet 7e5e3c4cc6 Adjust reconnect coro to swallow symbol data resp
Couple fixes here:
- if no tickers for a watchlist name -> bail
- swallow the symbol data response in the reconnect handler coro
- don't sleep 5 seconds before connecting to subproc daemon...

Tyler Goodlet 186befc704 Only run 'startup sequence' on reconnect
When a client loses a connection it will currently need to re-subscribe
for symbols and receive a symbol data summary as a first quote response.
Only run the provided coroutine on reconnect and call the kwarg
`on_reconnect`. The client consuming code is entirely expected at this
point to know how the symbol registration protocol works.

Tyler Goodlet 3646fb4a23 Filter out bad symbols before adding client subscription
Event if a broker client is already spawned new clients should still
receive a detailed symbol data packet as the first response. Avoid
exposing the new client's queue to the broker (i.e. subscribing it for
quotes) until after first pushing this packet with all bad symbols
filtered out.

Tyler Goodlet 4f387ea2be Fix subscriptions and connection handling
Oh boy where to start.

- Handle broken streams in the `StreamQueue` gracefully; terminate the
  async generator.
- When a stream queue connection is unwritable discard its subscriptions
  inside the quoter task
- If all subscriptions are discarded for a broker then tear down its
  quoter task
- Use listener parent nursery for spawning quoter tasks
- Make broker subs data structures global/shared between conn
  handler tasks
- Register the `tickers2qs` entry *after* instantiating broker client(s)
  (avoids race condition when mulitple client connections are coming
  online simultaneously)
- Push smoke quotes to every client not just the first that connects
- Track quoter tasks in a cross-task set
- Handle unsubscriptions more correctly
