ANSIfy various tools in usr.bin/.

Most of these tools properly build at WARNS=6, except for their K&R
function declarations. Fix this, so we can bump WARNS as well.

Revert most part of 200420 as requested, as more review and polish is
needed.

Remove unneeded header includes from usr.bin/ except contributed code.

Tested with: make universe

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

Stop generating the `register' keyword.

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.

Only write the dispatch table function prototypes to the header if the -h
flag was specified. If all files are generated at once, those functions are
static and shouldn't appear in the header.

- 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.

Removal of spaces at EOL. Add __FBSDID. New function xmalloc, xrealloc,
xstrdup. There is a crash() function that do cleaning before exiting the
program. The new functions are wrappers that make use of crash() in case
of allocation failure. warn, exit -> err.

WARNS=2

- TI-RPC is now the default again for code generation.

- As before, inetd support support is turned of per default.
Code for inetd can be made with -I.

- Support for ``transport monitors'' and the NLSPROVIDER env
variable is still there , even if their use is not clear in
non TLI stream based systems like Free-/NetBSD. It can be activated
with -P.

- There are a few corrections in rpcgen.1 and usage function to conform
to the code. Added and documented -P

- I removed the #ifdefs checks for Free-/NetBSD since we are the only
ones who use this code. MaxOS X may have the same limitations as
we have, so this code will correctly build for them.

- Generate correct cflags.

Have rpcgen output the prototypes for the dispatch tables

General -Wall warning cleanup, part I.
Submitted-By: Kent Vander Velden <graphix@iastate.edu>

Clean up. (I hope I'm doing this right.)

Update rpcgen with the one from the TI-RPC 2.3 distribution.

Note that when built for FreeBSD, this version of rpcgen assumes
backwards compatibility mode by default. This means that it will produce
ONCRPC 4.0 compatible code unless otherwise instructed, instead of the
other way around.

One incompatibility has also been worked around: this rpcgen normally
always emits an '#include <stropts.h>' directive whether you select
backwards compatibility mode or not. We don't have STREAMS, so this
behavior has been changed: now it will only emit this line if run in TI-RPC
mode.

The 'generate output files in current directory instead of the
directory where the protocol definition file lives' hack from the
original rpcgen has been preserved.

Notable new features:

- Can be used to generate RPC servers that can be launched
from port monitors such as inetd(5).

- Can generate ANSI C code.

- Can generate sample client and server top-level programs and
makefiles in addition to the usual client and server stubs.

- Can generate inline XDR routines.

Remove trailing whitespace.

Move RPC stub generator program over from 1.1.5.
