* Move configuration from lib/service to lib/service/servicecfg The new servicecfg package will hold only configuration for services. This will allow other packages (like tctl and tsh) to depend on servicecfg without pulling in all of lib/service (which has a number of platform-specific details). This is the first step towards being able to build tctl for Windows. * Move PAM and BPF config into servicecfg This breaks a compile-time dependency on BPF/PAM for tctl.
