For functions linked to virt tools, make sure the name of the function actually matches the virt tool. Because of the history of moving functions across tools, some names no longer matched. For mllib, use `guestfs_int_mllib_' prefix. For OCaml bindings, use `guestfs_int_ocaml_' prefix. This commit is by no means complete. There are many other C functions in other language bindings which could do with being more consistently named. There is no functional change, this is just refactoring.
