Description

event-listener allows !Send tags to cross thread boundaries via StackSlot

Affected versions of event-listener unconditionally implement Send and

Sync for StackSlot<'_, T>, the stack-allocated listener type created

by the listener! macro.

This allows a !Send tag type set via Event::with_tag to be moved to

another thread and accessed via StackSlot::wait, causing a data race in safe

code.
