sccs: Manual changes

For the uncommon items: Go through the tree and remove sccs tags that
didn't fit any nice pattern. If in the neighborhood, other SCM tags were
removed when they were detritis of long-ago CVS somehow in the early
mists of the project. Some adjacent copyrights stringswere removed (they
duplicated the copyright notices in the file). This also removed
non-standard formations of omission of SCCS tags (usually by adding an
extra #if 0 somewhere.

After this commit, a number of strings tagged with the 'what' @(#)
prefix remain, but they are primarily copyright notices.

rpcgen: Perform shell-style word expansion on RPCGEN_CPP

Up until recently, CPP has been a list of space-separated words, with no
quotes, backslashes or other characters with special meaning to a shell.
However, as of 8fad2cda93c7, (escaped) quotes appear in CPP, and the
rudimentary parser in rpcgen is insufficient, since it will leave the
escaped quotes as escaped rather than performing one level of expansion
as would be done by a shell (whether in a script or a Makefile).

Rather than hack around this in all the places RPCGEN_CPP gets set,
implement proper expansion inside rpcgen. Note that this only deals with
a subset of shell syntax, since we don't handle any of:

| & ; < > ( ) $ ` * ? [ # ˜ = %

having special meaning (with the exception of how a backslash behaves
inside double quotes, where \$ means a literal $ inside double quotes
but \a means a literal \a), instead using their literal value, but those
are all reasonable restrictions, and can be worked around by avoiding
their use; what's important is that we get the quoting and splitting
right.

This fixes -Winvalid-pp-token spew during build${libcompat}.

Pointy hat to: me
MFC after: 1 week

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is obsolete, and has been removed.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.

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.

Fix a #ifndef that became a #ifdef and changed the default
behaviour of rpcgen.

Noticed by: bde

Add #ifdefs for __NetBSD__ in the rest of the places where __FreeBSD__
is defined so that this program behaves the same when built with
either set of tools. The only difference is where the pre-processor
is found. And that is a bug - it should check the CPP environment
variable and the path before just assuming that the compiled in
path is OK. I guess we should be using -Y ${WORLDPATH}/usr/bin/cpp
during a bootstrap build.

Add __NetBSD__ in a couple of places to allow this program to
compile under NetBSD, but behave like FreeBSD. For the time being,
look for NetBSD's cpp in /usr/bin.

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.

Import a newer and more functional version of rpcgen.
