Title: New functionality to allow a pathway for writes with minimal overhead.

Hi,

I've added a new function to allow developers to bypass the not insignificant overheads of (for example) using mongo_batch_insert and have a more direct path to mongo_env_write_socket. This, if used, can make significant savings in overhead by avoiding redundant calls such as memcpy and various other checks.
