From c943380b7a2cc9b32f81c22224fc6f92e8ea8469 Mon Sep 17 00:00:00 2001
From: Werner Koch <wk@gnupg.org>
Date: Wed, 14 Sep 2016 12:41:16 +0200
Subject: core: New function gpgme_op_revuid.

* src/engine.h (GENKEY_EXTRAFLAG_REVOKE): New.
* src/genkey.c (adduid_start): Rename to addrevuid_start.  Add arg
REVOKE and pass it as extraflags.  Remove useless ARMOR extraflag.
Adjust callers.
(gpgme_op_revuid_start, gpgme_op_revuid): New.
* src/gpgme.def, src/libgpgme.vers: Add them.

* tests/run-genkey.c: Add option --revuid.
