RFR: 8310426: (ch) Channels.newInputStream transferTo cleanup

Tue Jun 20 17:52:04 UTC 2023

ChannelInputStream, the InputStream returned by Channels.newInputStream, implements the transferTo method with support for the cross product of many interesting underlying channels. It's getting a bit too unwieldy and can be simplified by introducing a FileChannelInputStream to wrap a FileChannel.
