cleanup: fix leakage of dirstate._map to client code
We already had proper accessors for most of the behavior of
dirstate._map that callers cared about exposed in the actual dirstate
class as public methods. Sigh.
There are two remaining privacy violations in the codebase after this change:
1) In the perf extension, which I suspect has to stick around because
it's really testing the dirstate implementation directly
2) In largefiles, where we deal with standins and mutating status. Looking at
this, I _strongly_ suspect a formal dirstate interface would allow
this to work via composition instead of inheritance and
monkeypatching. Fortunately, such wins are a part of my motivation
for this work. I anticipate we'll come back to this in due time.

This is useful to test local and uncommitted changes in an otherwise-clean source tree. This means that purge will delete the following by default: - Unknown files: files marked with "?" by :hg:`status` - Empty directories: in fact Mercurial ignores directories unless they contain files under source control management But it will leave untouched: - Modified and unmodified tracked files - Ignored files (unless --all is specified) - New files added to the repository (with :hg:`add`) The --files and --dirs options can be used to direct purge to delete only files, only directories, or both. If neither option is given, both will be deleted. If directories are given on the command line, only files in these directories are considered. Be careful with purge, as you could irreversibly delete some files you forgot to add to the repository. If you only want to print the list of files that this program would delete, use the --print option.
