ProtobufCMessage struct
An instance of a message. `ProtobufCMessage` is a light-weight "base class" for all messages. In particular, `ProtobufCMessage` doesn't have any allocation policy associated with it. That's because it's common to create `ProtobufCMessage` objects on the stack. In fact, that's what we recommend for sending messages. If the object is allocated from the stack, you can't really have a memory leak. This means that calls to functions like protobuf_c_message_unpack() which return a `ProtobufCMessage` must be paired with a call to a free function, like protobuf_c_message_free_unpacked().

Function
Description
Merge earlier message into a latter message. For numeric types and strings, if the same value appears multiple times, the parser accepts the last value it sees. For embedded message fields, the parser merges multiple instances of the same field. That is, all singular scalar fields in the latter instance replace those in the former, singular embedded messages are merged, and repeated fields are concatenated. The earlier message should be freed after calling this function, as some of its fields may have been reused and changed to their default values during the merge.
Initialise messages generated by old code. This function is used if desc->message_init == NULL (which occurs for old code, and which would be useful to support allocating descriptors dynamically).
Pack a ProtobufCMessage and return the number of bytes written. The output includes a length delimiter.
