As part of the new MongoClient.bulk_write API, we need to add support for C extensions, which get called during the process of constructing and sending the OP_MSG.
We should add two new entry points to _cmessagemodule.c: one for _client_encode_batched_op_msg() and one for _client_batched_op_msg(). Much of the existing C implementation for the collection-level bulk write can likely be reused.
