PR 371/pppd

  • pppd/auth.c, pppd/chat.c, pppd/demand.c, pppd/fsm.c, pppd/lcp.c, pppd/options.c, pppd/pppd.h, pppd/rtemsmain.c, pppd/rtemspppd.c: Change many symbols to static. There are still global symbols in rtemspppd.h which might need to be changed or converted into member of a structure which is dereferenced with a pointer that is managed as a per task variable. But this patch should avoid many conflicts.
