Changes

**Deprecation notice**:
- Setting service name via `DD_SERVICE_NAME` is now deprecated and will be removed in a future release. Use `DD_SERVICE` instead for consistency with other Datadog tracers and services.
- Setting global tags via `DD_TRACE_GLOBAL_TAGS` is now deprecated and will be removed in a future release. Use `DD_TAGS` instead (with the same format) for consistency with other Datadog tracers and services.
- `DD_TRACE_RESOURCE_URI_MAPPING` is deprecated now that it has been split into `DD_TRACE_RESOURCE_URI_MAPPING_INCOMING` and `DD_TRACE_RESOURCE_URI_MAPPING_OUTGOING`.
- The functions `dd_trace` and `dd_trace_forward_call` are deprecated and will be made a no-op in the next release. See #924 for how to migrate.
