This patch adds support for a new quota type PRJQUOTA for project quota enforcement. Also a new method get_projid() is added into dquot_operations structure.

I would add a precision in the comment: always allow querying project quota when the project id is mapped in the current user namespace. id is the id in the current user namespace. So quotas for unmapped users, unmapped groups or unmapped projects cannot be queried.
