That's why I asked for help. _CDDL_VISIBLE is not good, because it is
not related to CDDL license. _ZFS_VISIBLE is not good, because it is not
ZFS-specific. _{SUN,SOLARIS,OPENSOLARIS}_VISIBLE is also not good,
because it is already in Linux too. Solaris simply defines
__EXTENSIONS__. Maybe we need something like this? I don't think we need
separate _*_VISIBLE defines for every new #define in unistd.h and other
headers, so something similar to __EXTENSIONS__ makes sense to me.
