In kernel version >= v4.5 the project quota ioctl definitions
have been made public via the include/uapi/linux/fs.h API, so
that ext4 could use the same API.
Avoid re-defining the ioctl API if it is already defined in fs.h.

This class implements XFS project quota controls
for setting quota limits on a newly created directory.
It currently supports the legacy XFS specific ioctls.
Using this class, quota limits per container can be set
by directory based storage drivers (e.g. overlay), when
backing storage is XFS mounted with 'pquota' mount option.
TODO: use generic quota control ioctl FS_IOC_FS{GET,SET}XATTR
for both xfs/ext4 for kernel version >= v4.5
