gpgme/tests/run-genkey.c
Werner Koch c943380b7a
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.
