RFR: 8325028: (ch) Pipe channels should lazily set socket to non-blocking mode on first use by virtual thread

Wed Feb 7 11:45:04 UTC 2024

The Unix implementation of the Pipe source/sink channels eagerly configures the underlying socket to be non-blocking in case the pipe is used by a virtual thread. It can be done lazily, as done with the network channels. No changes to the semantics of the APIs, and well tested by the existing tests.
