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!
