dirstate._walkexplicit: rename work to dirsfound

This enables this code to be reused by extensions that implement the other,
more time-consuming bits of walk in different ways.
dirstate.walk: pull skipstep3 out of the explicit walk code
This is a move towards factoring out this code into a separate function.
dirstate.walk: move dirignore filter out of explicit walk code
This is a move towards factoring this code out into a separate function.
dirstate.walk: maintain a list of dirs not found

This helps us get there.
