For the reference, this version still passes the current set of ATF tests
for the getopt(3) function.

This version is by default unused.

Constness correction for the getopt(3) function under REPLACE_GETOPT

Use the __UNCONST() macro, which is used in the other parts for the same
argument nargv, but under the !REPLACE_GETOPT namespace.

ANSIfy. Remove conditionals around __RCSID.

Revert previous. This mess of ifdefs needs to be killed.

move the test to replace getopt higher up, before we need to include anything.

Fix several end cases:

o If a long option looks like an ambiguous abbreviation of two or more long
options, but all the possible interpretations would return the same
value, then just return that value without complaining that it's
ambiguous.

o If a long option could be interpreted either as an exact match for one
long option, or as an abbreviation for one or more other long options,
then treat it as the exact match.

These changes align NetBSD's getopt_long(3) with the current behavior of
GNU getopt_long(3), the de facto standard, and FreeBSD's getopt_long(3).

Completely rework how tools/compat is done. Purge all uses/references to
_NETBSD_SOURCE as this makes cross building from older/newer versions of
NetBSD harder, not easier (and also makes the resulting tools 'different')

Wrap all required code with the inclusion of nbtool_config.h, attempt to
only use POSIX code in all places (or when reasonable test w. configure and
provide definitions: ala u_int, etc).

Reviewed by lukem. Tested on FreeBSD 4.9, Redhat Linux ES3, NetBSD 1.6.2 x86
NetBSD current (x86 and amd64) and Solaris 9.

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).

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.
