Move to tame(int flags, char *paths[]) API/ABI.
The pathlist is a whitelist of dirs and files; anything else returns ENOENT.
Recommendation is to use a narrowly defined list. Also add TAME_FATTR, which
permits explicit change operations against "struct stat" fields. Some
other TAME_ flags are refined slightly.
Not cranking libc now, since nothing commited in base uses this and the
timing is uncomfortable for others. Discussed with many; thanks for a
few bug fixes from semarie, doug, guenther.
