yp_prot.h lies -> use yp.h (from yp.x) instead, change lots of structure

accesses to match. change xdr_domainname() and some other functions to
take "char **" instead of "char *", as rpcgen intended -- helps programs
linking against rpcgen output of yp.x.  yp_all() should not free it's
return value. split xdryp.c and yplib.c into ~20 files so binaries like
"csh" need not link in functions like yp_maplist(). NIS+'s YP emulation
code lacks YPPROC_ORDER... attempt to deal nicely.
