Bug 27816

	FreeBSD5.0-current uses know TI-RPC rpc library. Therefore rpcgen
	should generate TI-RPC code.
	But currently rpcgen generate protmap code by default, and the code
	for servers generated for TI-RPC (rpcgen -b) does not compile,
	for it reference TLI transport functions and not socket transport.

Fix: Below is a patch to generate correct code.
Some remarks
1/ I kept the old TI-transport code, and added an internal flag
   tirpc_socket (with no option to clear it) to control the generation.
2/ I reversed the -b flag: now TI-RPC is the default.
3/ Even if on many systems option -I (inetd support) is always on,
   I modified rpcgen to generate different code with option -I or
   without (simpler code). So explicit -I is needed for inetd support.
   This choice can be argued.
4/ There are a few corrections in rpcgen.1 and usage function to conform
   to the code.
5/ I kept a support for ``transport monitors'' and the NLSPROVIDER env
   variable, even if the use is not clear in non TLI stream based systems.

	% cp /usr/include/rpcsvc/rnusers.x .
	% rpcgen -b rnusers.x 
	% cc -o serv rnusers_svc.c
