I have used a programming idiom where I want to `xQueuePeek()` a message queue, and attempt to send the message. If the send succeeds, then I want to drop the message from the queue. At the moment, the only way to drop the message from the queue is to call `xQueueReceive()`, with a non-NULL value for `pvBuffer`.

It would be good if `xQueueReceive()` would accept a `NULL` value for `pvBuffer`, allowing it to drop the next entry in the queue without the overhead of copying it to a buffer.

What is the more likely path? If the send succeds more often, can you do xQueueReceive and do xQueueSend/xQueueSendToFront when send fails?
