api: verify message size on receipt
When a message is received, verify that it's sufficiently large to accomodate any VLAs within message. To do that, we need a way to calculate message size including any VLAs. This patch adds such funcionality to vppapigen and necessary C code to use those to validate message size on receipt. Drop messages which are malformed.
