Bug 1063 - Utilize own Uri and Uri.Encoded class w/ proper encoding and differentiating encoded/decoded variants by type [Part 1]

- Add immutable com.jogamp.common.net.Uri class impl. RFC 2396 w/ encoding of RFC 3986

- Class Uri.Encoded is used to represent encoded parts

- IOUtil: Remove unused methods (residing in Uri) and mark others deprecated (will move to Uri)

- Adopt usage of Uri: This must be completet in follow-up commits!
