Normalize and add options for backup, add more file flags options

Browse Source 
- Move more function arguments to structs with some convenience
functions.
- Add a flag to enable backup/restore of file flags. It works a little
bit differently depending on system. Since we don't need to do anything
to get file flags on darwin/BSD, it's in the stat buffer so just save it.
For linux we have to open the file and do a
- Add the normalize flag to ReadAttributes. Implementation TBD.
- stub out common xattr file for doc comments
