Module Name:    src

Modified Files:
        src/sys/kern: vfs_syscalls.c
        src/sys/sys: vfs_syscalls.h

Log Message:
As discussed on tech-kern:

Factor out common code of chroot-like syscalls into change_root() and export
that function for use in other parts of the kernel.
Rename change_dir() to chdir_lookup() as the latter describes better what
the function does.  While there, move the namei_data initialisation into
chdir_lookup(), too.  And export chdir_lookup().
