debugstate: Always call dirstatemap.debug_iter()...
debugstate: Always call dirstatemap.debug_iter() … passing it a new `all` argument for the `--all` CLI option, instead of conditionally calling `.debug_iter()` or `.items()` This prepares for the next commit. Differential Revision: https://phab.mercurial-scm.org/D11462

"""Map encapsulating the dirstate's contents.
The dirstate contains the following state:
- `identity` is the identity of the dirstate file, which can be used to
detect when changes have occurred to the dirstate file.
- `parents` is a pair containing the parents of the working copy. The
parents are updated by calling `setparents`.
- the state map maps filenames to tuples of (state, mode, size, mtime),
where state is a single character representing 'normal', 'added',
'removed', or 'merged'. It is read by treating the dirstate as a
dict. File state is updated by calling various methods (see each
documentation for details):
- `reset_state`,
- `set_tracked`
- `set_untracked`
- `set_clean`
- `set_possibly_dirty`
- `copymap` maps destination filenames to their source filename.
The dirstate also provides the following views onto the state:
- `nonnormalset` is a set of the filenames that have state other
than 'normal', or are normal but have an mtime of -1 ('normallookup').
- `otherparentset` is a set of the filenames that are marked as coming
from the second parent when the dirstate is currently being merged.
- `filefoldmap` is a dict mapping normalized filenames to the denormalized
form that they appear as in the dirstate.
- `dirfoldmap` is a dict mapping normalized directory names to the
denormalized form that they appear as in the dirstate.
