ANSIfy, static + __dead

Sync with wrstuden-revivesa-base-2.

Remove the \n and tabs from the __COPYRIGHT() strings.
Tweak to use a consistent format.

WARNS=3

Overhaul how `build.sh tools' are used:

    *	Rename "config.h" to "nbtool_config.h" and
	HAVE_CONFIG_H to HAVE_NBTOOL_CONFIG_H.
	This makes in more obvious in the source when we're using
	tools/compat/config.h versus "standard autoconf" config.h

    *	Consistently move the inclusion of nbtool_config.h to before
    	<sys/cdefs.h> so that the former can provide __RCSID() (et al),
    	and there's no need to protect those macros any more.

These changes should make it easier to "tool-ify" a program by adding:
	#if HAVE_NBTOOL_CONFIG_H
	#include "nbtool_config.h"
	#endif
to the top of the source files (for the general case).

safer use of realloc

Move UCB-licensed code from 4-clause to 3-clause licence.

Patches provided by Joel Baker in PR 22365, verified by myself.

Roll in fixes to permit cross-compiling from non-NetBSD hosts.  This
round has been tested on Solaris/x86 and Linux hosts.

* Add host tools cap_mkdb, ctags, m4, uudecode.
* Protect __RCSID() and __COPYRIGHT() better.
* Reduce the number of places that need to include "config.h", to keep
  sources closer to their "vanilla" versions.
* Add more compat #defines and autoconf-checked functions.

Add hooks for cross-hosting on non-NetBSD platforms.

Fix various misspellings of compatible/compatibility.

call setprogname(argv[0]) at start of main()

Add { and } to shut up egcs. Reformat the more questionable code.

WARNSify, fix .Nm usage, getopt returns -1 not EOF, use ANSI <string.h> funcs

Add a `-q' option, to be quiet about cycles.  From der Mouse, PR 1204.

update with latest, from christos@deshaw.com

fix from Frank van der Linden <vdlinden@fwi.uva.nl> to DTRT when given a
filename on the command line.

from Jarle.F.Greipsland@idt.unit.no:
find_cycle was trying to find the longest cycle that a given node is part of,
which is a really, really hard problem (exponential?).  instead, just detect
cycles.  since the only difference is the (std error) output which is printed,
all works out OK.

fix that last

long lost fix from Christos Zoulas (?) for inf. loop problem

Add RCS identifiers.
