context: add private _dirstatestatus method

This method is mostly a copy from workingctx.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.

You mean localrepo.status?  This code doesn't exist in workingctx.status 
yet.

In localrepo.status, this line is 'if parentworking and cmp:' which 
implies that the code above could be used in a situation where we're not 
comparing against the parent, and that the code below should only be run 
if we are comparing against parent.  So... how will that get handled now?

Oops, yep. I meant from localrepo.status.

This patch series is trying to get rid of the need to have a
'parentworking' variable at all and call the workingctx.status method
directly. In other words, the 'parentworking' check will be done before
calling this method. This helps remove the parentworking logic from this
code.
