Use ANSI definitions.
Avoid using extern by declaring shared functions in header files.

Don't generate K&R C code. The -C flag is kept for backwards compatibility.
Also remove the SIG_PF macro, there is no need to cast closedown.

- Use prototypes in headers.
- Include rpc_scan.h before rpc_util.h for the tok_kind enum.
- Nuke unused declarations.

Move #ident into #if 0.

back out 1.7 changes, unneeded and possibly wrong.

Modify rpcgen -t output to something that's a lot more useful in
today's modern "no sir, not today" compilers.

Basically, when building the table:

use NULL instead of 0,
use braces around array initializers,
case the function pointers to xdrproc_t,
don't cast function pointers that do not need casting.
