Improved log msg formatting in core
As part of solving some final edge cases todo with inter-peer remote
cancellation (particularly a remote cancel from a separate actor
tree-client hanging on the request side in `modden`..) I needed less
dense, more line-delimited log msg formats when understanding ipc
channel and context cancels from console logging; this adds a ton of
that to:
- `._invoke()` which now does,
- better formatting of `Context`-task info as multi-line
`'<field>: <value>\n'` messages,
- use of `trio.Task` (from `.lowlevel.current_task()` for full
rpc-func namespace-path info,
- better "msg flow annotations" with `<=` for understanding
`ContextCancelled` flow.
- `Actor._stream_handler()` where in we break down IPC peers reporting
better as multi-line `|_<Channel>` log msgs instead of all jammed on
one line..
- `._ipc.Channel.send()` use `pformat()` for repr of packet.
Also tweak some optional deps imports for debug mode:
- add `maybe_import_gb()` for attempting to import `greenback`.
- maybe enable `stackscope` tree pprinter on `SIGUSR1` if installed.
Add a further stale-debugger-lock guard before removal:
- read the `._debug.Lock.global_actor_in_debug: tuple` uid and possibly
`maybe_wait_for_debugger()` when the child-user is known to have
a live process in our tree.
- only cancel `Lock._root_local_task_cs_in_debug: CancelScope` when
the disconnected channel maps to the `Lock.global_actor_in_debug`,
though not sure this is correct yet?
Started adding missing type annots in sections that were modified.
