cc7532aaf0 Add a sysctl variable which can help stop chroot(2) escapes. 
kern.chroot_allow_open_directories = 0
	chroot(2) fails if there are open directories.

kern.chroot_allow_open_directories = 1 (default)
	chroot(2) fails if there are open directories and the process
	is subject of a previous chroot(2).

kern.chroot_allow_open_directories = anything else
	filedescriptors are not checked.  (old behaviour).

I'm very interested in reports about software which breaks when
running with the default setting.

8b3cccfc04 Remove the EINVAL error from the ERRORS sections that 
say is means that a pathname had the high-order bit
set, since this is no longer an error.
