[SPARK-6898][SQL] completely support special chars in column names
Even if we wrap column names in backticks like `` `a#$b.c` ``, we still
handle the "." inside column name specially. I think it's fragile to use a
special char to split name parts, why not put name parts in
`UnresolvedAttribute` directly?
