* wrapup/Makefile.am: Added modem subdir. * configure.in, Makefile.am: Added modem subdir. * net/Makefile.am: Added if_pppvar.h, pppcompress.h. * pppd/Makefile.am: Added pppmain.c (which needs work). * pppd/chat.c, pppd/fsm.c, pppd/fsm.h, pppd/ipxcp.c, pppd/main.c, pppd/ppp_tty.c, pppd/upap.c: Changes from Thomas Doerfler <Thomas.Doerfler@imd-systems.de> and cosmetic changes by me. Actually main.c and ppp_tty.c should be scratched. The modem subdir has the real ppp_tty.c and the real pppd main is in pppmain.c.
