MFC r231079:

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is obsolete, and has been removed.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.

MFC r231080:

Amend r231079 by properly shifting up the existing arguments in
rpc_main.c's insarg() function. I had forgotten to put this in my patch
queue, sorry.

Pointy hat to: me

MFC r231101:

In usr.bin/rpcgen/rpc_main.c, use execvp(3) instead of execv(3), so
rpcgen will search the current PATH for the preprocessor. This makes it
possible to run a preprocessor built during the cross-tools stage of
buildworld.

The appropriate argument is -K -1, not -k -1.

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.

Markup nit.

Mechanically kill hard sentence breaks.

mdoc(7) police: markup polishing.

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.

- 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.

Use `The .Nm utility'

Remove whitespace at EOL.

Turn -b (BSD socket compat mode) back on by default, as we don't have TLI/XTI

Bring in a hybrid of SunSoft's transport-independent RPC (TI-RPC) and
associated changes that had to happen to make this possible as well as
bugs fixed along the way.

Bring in required TLI library routines to support this.

Since we don't support TLI we've essentially copied what NetBSD
has done, adding a thin layer to emulate direct the TLI calls
into BSD socket calls.

This is mostly from Sun's tirpc release that was made in 1994,
however some fixes were backported from the 1999 release (supposedly
only made available after this porting effort was underway).

The submitter has agreed to continue on and bring us up to the
1999 release.

Several key features are introduced with this update:
Client calls are thread safe. (1999 code has server side thread
safe)
Updated, a more modern interface.

Many userland updates were done to bring the code up to par with
the recent RPC API.

There is an update to the pthreads library, a function
pthread_main_np() was added to emulate a function of Sun's threads
library.

While we're at it, bring in NetBSD's lockd, it's been far too
long of a wait.

New rpcbind(8) replaces portmap(8) (supporting communication over
an authenticated Unix-domain socket, and by default only allowing
set and unset requests over that channel). It's much more secure
than the old portmapper.

Umount(8), mountd(8), mount_nfs(8), nfsd(8) have also been upgraded
to support TI-RPC and to support IPV6.

Umount(8) is also fixed to unmount pathnames longer than 80 chars,
which are currently truncated by the Kernel statfs structure.

mdoc(7) police: use the new features of the Nm macro.

Remove single-space hard sentence breaks. These degrade the quality
of the typeset output, tend to make diffs harder to read and provide
bad examples for new-comers to mdoc.

Reduce the number of args to .%T to an acceptable number by
removing the `Nm' command from the line. This means that %T
will actually work.

Fxi various man pages to stop abusing the .Bx macro to generate
the string "FreeBSD". Use the .Fx macro instead. Also did some
minor re-wording/formatting to work around a deficiency with
the .Fx macro when it comes to puncuation characters other than
periods and commas.

$Id$ -> $FreeBSD$

Add $Id$, to make it simpler for members of the translation teams to
track.

The $Id$ line is normally at the bottom of the main comment block in the
man page, separated from the rest of the manpage by an empty comment,
like so;

.\" $Id$
.\"

If the immediately preceding comment is a @(#) format ID marker than the
the $Id$ will line up underneath it with no intervening blank lines.
Otherwise, an additional blank line is inserted.

Correct formatting error in display of the "-i size" option description section.

Convert to mdoc.

Minor cleanup of the rpc man pages to silence manck.

Correct some manual page cross reference errors. E.g. su is a section
one man page, not section eight. This is the first round of such changes
and only fixes man pages in manual section one.

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.

Move RPC stub generator program over from 1.1.5.
