Add EOL stream type detection to TreeWalk

TreeWalk provides the new method getEolStreamType. This new method can
be used with EolStreamTypeUtil in order to create a wrapped InputStream
or OutputStream when reading / writing files. The implementation
implements support for the git configuration options core.crlf, core.eol
and the .gitattributes "text", "eol" and "binary"
