pchickey opened PR #1961 from pch/sync_wasi_pipe to main:

Follow up to #1949

When we went to integrate this code, we discovered that we needed these virtual pipes to be Send and Sync. So, I have switched the internal types from Cell/RefCell/Rc to Arc/RwLock.

The RwLock.{read, write} results are always unwrap()ed because this code does not expose any way for a panic to occur while a lock is held.

We also identified that the Handle::try_clone method was incorrect, and did a manual impl of Clone with the correct semantics.
