add missing include files

branches: 1.22.42;
Change all the 'return(x)' to 'return c'.
Makes some other searches I want to do a bit easier.

appease gcc -Wuninitialized on hp700.

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).

Revert previous change, and fix the -T problem differently: When the options
of the second argument are exhausted, call the appropriate getopt() routine
to process the rest of the arguments instead of finishing option processing.
Fixes:
tar cf - -T foo

Simplify the way we deal with old argument style. Old way was broken when
tar cf - -T dir

add a "+" to the options string rather than setting POSIXLY_CORRECT

merge OpenBSD changes:
- correct -C processing
- add ability to read filenames and flags from a file
- don't print dangerous escape sequences to the terminal
- use strlcpy/strncpy properly.
- handle tmpfile creation better.
- improve documentation of options.
- handle stdout/stderr list selection correctly.
- kill gzip when we get interrupted.
- simplify gzip setup.
- add more flags to programs.

additional changes:
- librmt processing.
- set POSIXLY_CORRECT in options parsing.
- prevent more string overruns.
- support -T

we don't turn the switch on to replace tar and cpio yet.

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.

Make almost all tools compile and run properly on non-NetBSD hosts. (In
particular, most tools now run correctly on Solaris 7.)

fix WARNS=2

- ansi KNF (just remove all the #ifndef __STDC__ prototype junk,
leaving the ansi stuff)
- use longlong_t instead of quad_t (etc), and rename *uqd*() -> *ull*()
- clean up the NET2_STAT stuff similar to ftpd; provide #defines and
macros which select which cast to use, etc
- clean up the NET2_FTS and NET2_REGEX #define use

Add GNU tar-style long options for pax's tar front-end. Still many
GNU options not implemented, but there is an #if 0'd out canonical
list.

Don't declare 'extern opt*' getopt variables.

Cleanup and fix typos.
Partially from FreeBSD.

getoldopt is expect to return -1 (not EOF), so "make it so"

* cleanup manpage
* getopt returns -1 not EOF
* deprecate register

- Rename local warn so tty_warn that we can include <err.h> since this program
uses err() and errx().
- Fix printf format strings.
- Added WARNS=1; note
- Added missing prototypes.
- Split overloaded trail function into trail() and subtrail().

Fixed typo in comment

convert to new RCS id conventions.

from James Jegers <jimj@miller.cs.uwm.edu>: quiet -Wall, and squelch
some of the worst style errors.

Whoever wrote the tar command line argument parsing code didn't realize
that the order of arguments is different if the command flags are specified
without a `-'. I've integrated getoldopt.c from John Gilmore's pdtar which
handles argument parsing correctly.

fix botched pullup from ticket #1021 and make sure this compiles on
non-NetBSD hosts again. Also fixes PR#24481

Pullup rev 1.15-1.19 (requested by rafal in ticket #1021)
