clean statfs-like syscalls up
New helpers: user_statfs() and fd_statfs(), taking userland pathname and
descriptor resp. and filling struct kstatfs. Syscalls of statfs family
(native, compat and foreign - osf and hpux on alpha and parisc resp.)
switched to those. Removes some boilerplate code, simplifies cleanup
on errors...
