Split netload into netload and netinfo.

1999-11-28 Martin Baulig <martin@home-of-linux.org> Split netload into netload and netinfo. * include/glibtop/netinfo.h: New file. * include/glibtop/netload.h (glibtop_netload): Moved `if_flags', `mtu', `subnet' and `address' into the new `glibtop_netinfo'. * include/glibtop/sysdeps.h (GLIBTOP_SYSDEPS_NETINFO): Added. (glibtop_sysdeps): Added `netinfo. * include/glibtop/union.h (glibtop_union): Added `netinfo. * include/glibtop/command.h (GLIBTOP_CMND_NETINFO): Added.
