opensmtpd.table-redis: init at 1.0.1
The opensmtpd-extra package has been deprecated in favor of standalone
repositories for each of the filters. Introduce table-redis, which is
one of these new standalone filters to read login info from a Redis
instance.
Building table-redis does not work out of the box: while the project
correctly includes the hiredis include directory, the header itself is
contained in a "hiredis/" subdirectory. Add a patch to fix this.
