madsim-tokio

Removed

• Remove Handle::spawn and Handle::spawn_blocking as the implementation is incorrect.

Added

• Implement Debug for Handle and AbortHandle.

Fixed

• When MADSIM_ALLOW_SYSTEM_THREAD is set, executor won't panic when no task is ready.

Fixed

• Fix the problem that Handle::spawn spawns the task in a new node.

Added

• Add Runtime::handle().

Added

• Add a fake runtime::Handle. Note that this is a re-export of madsim::task::Handle. Tasks spawned with this handle are not correctly associated with the tokio runtime.
