(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.
