Thanks. Committed with two small changes:
 - added const to EC_GROUP to avoid warning
 - call i_debug() only with verbose_ssl

The login-common/ssl-proxy-openssl.c will go away in some future version
and be replaced by the code in lib-ssl-iostream. I added the code there
as well: http://hg.dovecot.org/dovecot-2.2/rev/dc99912e5047
