context: add private _dirstatestatus method

This patch is a step forward in getting rid of needing to check 'parentworking'
throughout the status method. Eventually, we will use the power of inheritance
to do the correct thing when comparing the working directory with its parent.

This method is mostly a copy from localrepo.status. The custom status method of
workingctx will eventually be absorbed by the refactoring of localrepo.status
to context.status but unfortunately we can't do it in one step.
