Add dmapd, krb5, netatalk, openldap, and other packages to the new GitHub repository

I would like to add dmapd, krb5, netatalk, openldap, as well as other related programs and their dependencies to the new GitHub repository. Included in the dependencies are the GStreamer 1.0+ packages mentioned recently on the openwrt-devel mailing list. I personally use each of these packages, and would be willing to serve as their maintainer.
