localrepo: access status fields by name rather than index

subrepo: use separate instances of empty lists in status We do modify the lists that make up the status in several places, so it seems risky to use the same instance of a list for several different status types. Use a separate empty list for each type instead.

summary: make status code more readable In commands.summary(), we currently zip a list of labels with a list of statuses. This means the order of the status list has to match the list of the labels, which in turn means the status elements have to be inserted into specific places in the list. Let's instead group the labels and status data we want to display in a single list of pairs.

strip: make checklocalchanges() return full status tuple By making checklocalchanges() return the full instance of the status class instead of just the first 4 elements of it, we can take advantage of the field names and not require the caller to remember the element indices.
