Breaks out all the (sub)actor local conc primitives from `Lock` (which
is now only used in and by the root actor) such that there's an explicit
distinction between a task that's "consuming" the `Lock` (remotely) vs.
the root-side service tasks which do the actual acquire on behalf of the
requesters.
`DebugStatus` changeover deats:
------ - ------
- move all the actor-local vars over `DebugStatus` including:
- move `_trio_handler` and `_orig_sigint_handler`
- `local_task_in_debug` now `repl_task`
- `_debugger_request_cs` now `req_cs`
- `local_pdb_complete` now `repl_release`
- drop all ^ fields from `Lock.repr()` obvi..
- move over the `.[un]shield_sigint()` and
`.is_main_trio_thread()` methods.
- add some new attrs/meths:
- `DebugStatus.repl` for the currently running `Pdb` in-actor
singleton.
- `.repr()` for pprint of state (like `Lock`).
- Note: that even when a root-actor task is in REPL, the `DebugStatus`
is still used for certain actor-local state mgmt, such as SIGINT
handler shielding.
- obvi change all lock-requester code bits to now use a `DebugStatus` in
their local actor-state instead of `Lock`, i.e. change usage from
`Lock` in `._runtime` and `._root`.
- use new `Lock.get_locking_task_cs()` API in when checking for
sub-in-debug from `._runtime.Actor._stream_handler()`.
Unrelated to topic-at-hand tweaks:
------ - ------
- drop the commented bits about hiding `@[a]cm` stack frames from
`_debug.pause()` and simplify to only one block with the `shield`
passthrough since we already solved the issue with cancel-scopes using
`@pdbp.hideframe` B)
- this includes all the extra logging about the extra frame for the
user (good thing i put in that wasted effort back then eh..)
- put the `try/except BaseException` with `log.exception()` around the
whole of `._pause()` to ensure we don't miss in-func errors which can
cause hangs..
- allow passing in `portal: Portal` to
`Actor.start_remote_task()` such that `Portal` task spawning methods
are always denoted correctly in terms of `Context.side`.
- lotsa logging tweaks, decreasing a bit of noise from `.runtime()`s.
