- Remove chkconfig usage for ypbind in dhclient-script (#351211)
    - Combine dhcp-static and dhcp-devel packages since there are no shared
        libraries offered
    - Remove Requires: openldap-devel on dhcp-devel and libdhcp4client-devel
    - Make libdhcp4client-devel require dhcp-devel (for libdhcp_control.h)
    - Do not make dhcp-devel require the dhcp package, those are independent
