vppapigen: support per-file (major,minor,patch) version stamps
Add one of these statements to foo.api: vl_api_version 1.2.3 to generate a version tuple stanza in foo.api.h: /****** Version tuple *****/ vl_api_version_tuple(foo, 1, 2, 3) Change-Id: Ic514439e4677999daa8463a94f948f76b132ff15 Signed-off-by: Dave Barach <dave@barachs.net> Signed-off-by: Ole Troan <ot@cisco.com>
