statvfs(2) reports wrapped sizes for large nfs file systems
nfs only implements vfs_statfs and relies on the vfs_stdstatvfs wrapper to
provide a statvfs interface.
NFSv3 provides 64 bit values for free and available blocks, but the statfs
structure it fills uses only signed longs. As a result, these values get
cropped and later written back into a 64 bit integer in the statvfs struct,
leading to incorrect information.
nfs needs to implement both statfs and statvfs to fix this.
