* mount: report . and .. from windows directories
WinFsp strips the dot entries for the root itself and expects every other
directory to report them, the way a real NTFS enumeration does: its
dirctl test asserts a subdirectory's first two entries are "." and ".."
and that a hundred files enumerate as 102 entries. Dropping them
unconditionally is what fails querydir_test.
The Go test that guarded the old behaviour went with it: os.File.Readdir
filters dot entries itself, so it could never have observed either way.
* mount: give the windows dot entries their directory type
The readdir fills an attribute block only for real children, so "." and
".." arrived with a zeroed one and were reported with mode 0. Windows
refuses to enumerate a directory whose first entry is not marked as a
directory, which is the assertion querydir_test fails on with
STATUS_OBJECT_NAME_NOT_FOUND.
They now carry the type the readdir already knew. The explorer walk also
names any unexpected entry rather than only counting, so a dot entry
leaking through reads differently from a missing file.
