Place them in the library, so iptables and nftables do not need to
redefine them.

flow table support needs constant object arguments to printing functions
to avoid ugly casts. While at it, also constify object arguments to message
construction, destructor and a few helper functions.

These functions allow to create a buffer (struct nftnl_udata_buf) of
user data attributes in TLV format (struct nftnl_udata). It is inspired
by libmnl/src/attr.c. It can be used to store several TLVs sequentially
into an object.
Example:
struct nftnl_udata_buf *buf;
struct nftnl_udata *attr;
const char *str = "Hello World!";
buf = nftnl_udata_buf_alloc(UDATA_SIZE);
if (!buf) {
perror("OOM");
exit(EXIT_FAILURE);
}
if (!nftnl_udata_put_strz(buf, MY_TYPE, str)) {
perror("Can't put attribute \"%s\"", str);
exit(EXIT_FAILURE);
}
nftnl_udata_for_each(buf, attr)
printf("%s\n", (char *)nftnl_udata_attr_value(attr));
nftnl_udata_buf_free(buf);
