Populate all necessary statfs members in .vfs_statfs. cd9660, udf,

msdosfs and nfsv2 don't set f_namemax. ntfs and ext2fs don't set
f_namemeax and f_favail. fusefs doesn't set f_mntfromspec, f_favail and
f_iosize. Also, make all filesystems use copy_statfs_info(), so that all
statfs information is filled in correctly for the (sb != &mp->mnt-stat)
case.
