We will need to refer to external heaps in some way. While we use heap ID's internally, for external API use it has to be something more user-friendly. So, we will be using a string to uniquely identify a heap. This breaks the ABI, so document the change. Signed-off-by: Anatoly Burakov <anatoly.burakov@intel.com>
