Introduce file_getattr and file_setattr syscalls to manipulate inode
extended attributes/flags. The syscalls take parent directory fd and
path to the child together with struct fsxattr.
This is an alternative to FS_IOC_FSSETXATTR ioctl with a difference
that file don&#
slate EOPNOSUPP back for current users - overlayfs, encryptfs
and fs/ioctl.c.

and read-only field fsx_nextents to
filesystem.
These changes should not affect existing chattr programs that use the
ioctl to get fsxattr before setting the new values.
