	* support/include/nfs/export.h addedd NFSEXP_NOSUBTREECHECK
	* support/nfs/exports.c: added {no_,}subtree_check and changed
	crossmnt to nohide
	* utils/exportfs/exports.man: added no_subtree_check and nohide
	and removed irrelevant stuff from unfsd.
	* support/export/rmtab.c: rmtab_read didn't quite do the right
	thing if a pathname from rmtab was a subdirectory of an export-point
