Amend r231079 by properly shifting up the existing arguments in

Let rpcgen(1) support an environment variable RPCGEN_CPP to find the C
preprocessor to run. Previously, it always ran /usr/bin/cpp, unless you
used the -Y option, and even then you could not set the basename. It
also attempted to run /usr/ccs/lib/cpp for SVR4 compatibility, but this
is obsolete, and has been removed.

Note that setting RPCGEN_CPP to a command with arguments is supported,
though the command line parsing is simplistic. However, setting it to
e.g. "gcc46 -E" or "clang -E" will lead to problems, because both gcc
and clang in -E mode will consider files with unknown extensions (such
as .x) as object files, and attempt to link them.

This could be worked around by also adding "-x c", but it is much safer
to set RPCGEN_CPP to e.g. "cpp46" or "clang-cpp" instead.

Replace index() and rindex() calls with strchr() and strrchr().

The index() and rindex() functions were marked LEGACY in the 2001
revision of POSIX and were subsequently removed from the 2008 revision.
The strchr() and strrchr() functions are part of the C standard.

This makes the source code a lot more consistent, as most of these C
files also call into other str*() routines. In fact, about a dozen
already perform strchr() calls.

# This hasn't been tested, and there are at least three bad commits

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.

sysent.h is installed as sys/sysent.h, so reflect it.

Eliminate coredump problem introduced by last commit.

Noticed by: Guido van Rooij <guido at gvr dot org>

Eliminate build breakage due to warnings about const.

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

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.
