pathspec: add copy_pathspec
Because free_pathspec wants to free "items" pointer in the pathspec
structure, a simple structure assignment is not enough if you want to
copy an existing pathspec into another. Freeing the original will
damage the copy unless a deep copy is made.
Note that the strings in pathspec->items->match and the array
pathspec->raw[] are still shared between the original and the copy.
