dirstate: swap pathto() and get_entry() in idirstate

This way the order of methods in dirstate and idirstate classes is the same.
Just to make it easier to use diff tools to compare the two classes.

# of the required typing inheritance, just use BinaryIO when typechecking, and
# ``object`` otherwise.
