udata: add TLV user data infrastructure
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);
