[Libguestfs] [PATCH 0/4] Add various ntfs* tools and unify label setting.

This miscellaneous patch adds bindings for: - ntfsfix - ntfsclone - ntfslabel and unifies filesystem label setting through a single API 'set-label' which replaces 'set-e2label' and is also able to set labels on NTFS using the ntfslabel program. 'ntfsfix' has been added as a possible way to fix RHBZ#797760. However I have not found a way to fully fix this bug. See discussion in the bug. 'ntfsclone-in' and 'ntfsclone-out' have been added at the request of a user. Rich.
