NonBlockingFileIO.read(...) don't error if more than 4 GiB is requested about swift-nio

We should also upgrade some of the Int types that express file sizes to Int64 so 4GB+ sizes can actually be supported on 32bit systems. I think this only affects the byteCount parameter of readChunked. This can be done separately and will need to preserver and deprecate the old function signatures. Note that offset is already Int64.

We don't need > 32 bit chunks. Reasonable chunk sizes are in kiB or MiB

Agree but I'm talking about the byteCount parameter, not the chunkSize parameter of the readChunked(...) method.

Fair enough!
