Expose Annotation Ids as C constants.

Prior to this change, the annotation ids are hardcoded at statsd's
clients. Expose them from libstatssocket so all clients can share these constants
living inside statsd apex.
Note: Currently, only statsd itself is logging events containing
annotations using native API.
