api: improve REPLY_MACRO safety
Improve vppapigen to generate per-message #define indicating whether said message is dynamically sized (due to VLA or string) or not. Use these #defines in REPLY_MACROs to prevent improper usage. Fix existing improper REPLY_MACRO* usage. Type: improvement Change-Id: Ia77aaf9f6cf3ed68ea21075a4cc8deda78a68651 Signed-off-by: Klement Sekera <ksekera@cisco.com>
