RFR: 8341666: FileInputStream doesn't support readAllBytes() or readNBytes(int) on pseudo devices [v4]

[Brian Burkhalter]

> Modify `FileInputStream` (FIS) to fall back to the superclass implementations of `readAllBytes()`, `readNBytes(int)`, `skip()`, and `transferTo` when the input source would otherwise fail with "Illegal Seek" in the FIS implementation, such as for the standard input or a named pipe.
