- drop dependency on glib, strlcpy can be implemented with snprintf with glibc/linux - drop "quilt" from buildrequires, no longer used. - Use fvisibiliy=hidden to build, this is a program not a library and no symbols should be exported. - modified patches: * glib-strlcpy.patch OBS-URL: https://build.opensuse.org/request/show/214314 OBS-URL: https://build.opensuse.org/package/show/network:utilities/netcat-openbsd?expand=0&rev=14
