Bruce Evans 3a76a5949b Merged Lite2's vfs_sysctl(). It doesn't fit very well into FreeBSD's
(phk's) sysctl framework, and I needed special code to disambiguate
the VFS_GENERIC node from the VFS_VFSCONF leaf, so I only converted
the leaves to the FreeBSD framework.  The error handling isn't quite
right.  CSRGS's sysctls seem to return ENOTDIR too much and FreeBSD's
sysctls don't agree with the man page.
