pax: fix typos in comments in file_subs.c & tar.c

Stamp out "greengrocers' apostrophes" in various places (arguably there
are still more present, but style guides vary on that, and my energies
spent corralling wayward punctuation marks could be spent elsewhere).

PR/20071: Perry Metzger: --extract handling is broken. This patch fixes

branches: 1.61.2;
The quagga-0.98.2 tar archive is busted. It was created with an old tar
program, and then someone appended to it a ustar record. Detect this and
warn, but don't treat it as an error.

Improve error reporting for invalid tar archives.

In GNU-tar mode, don't split filenames to prefix+name because GNU tar does
not honor it.

Keep track of the length of the gnu long name/link hack, so that
we can append to it. Modify the code so that file_write is re-entrant,
even in the gnu long name/link hack.

The old code assumed that the buffer already contained the necessary
blocks to satisfy the read file request that contained the long
filename. This is not always the case, specially when we are dealing
with pipes which do shorter reads, thus having more probability
that a long file name will fall across a buffer boundary.

To reproduce, create a tar archive with a lot of gnu-long-names
(pkgsrc/devel/libsigc++2 is a good example), do a tar -tf to get
a list of filenames, compress it and do a tar -tzf to get another
list of the filenames. Notice that the two lists differ.

- Grr! unterminated buffer string in exclude destination buffer
- fix isfoo() ctype macros to take unsigned char.

PR/25934: Dieter Baron: hard links with long names still fail.
As mentioned in the previous commit, the switch statement in the longlink()
needed simplification and it was a bit incorrect. Only depend on the passed
type to determine what kind of gnu longlink to produce. Don't try to deduce
it from the archive file type.

PR/25934: Dieter Baron: tar and hardlinks with long filenames don't work.
- always put the @LongLink tag on the name, not the long-link name.
- pass in what type of long name record we want to create; one for long-name
or long-link name.
XXX: We should get rid of the switch too.

Restructure the code to make it more readable. No functional changes.

While the comment is not correct anymore, this fixes the problem of tar -rf
where tar would skip backwards too much, corrupting the current tar archive
on append.

Don't emit any warnings when tar is trying to figure out if the file is
really tar format. valid CPIO files should not trigger a warning from tar.c

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).

Make this build on the Alpha.

implement the gnutar -X flag in terms of pax -s. fix some bugs in pax -s handling while i am here...

Reconstruct a split file name correctly.

Transparently handle old-style GNU tar archives that may have garbage in
the trailing block and do not have an end-of-archive marker. (Does this
handling based on whether the ustar id is "ustar" or "ustar ".)

Use the uid/gid caching moved into libc. Fixed a memory leak!

branches: 1.9.2;
- 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().

Fix OBOB: when reassembling a file name from the header block's `prefix'
and `name' fields, don't overwrite the glueing '/' between them.

Use '0' to front-pad octal strings, not ' '.

kill 'register'

convert to new RCS id conventions.

Eliminate uses of some obsolete functions.

Fix up RCS ids.

Pullup rev 1.58 (requested by christos in ticket #921)

Keep track of the length of the gnu long name/link hack, so that
we can append to it. Modify the code so that file_write is re-entrant,
even in the gnu long name/link hack.

Pullup rev 1.59 (requested by christos in ticket #920)

In GNU-tar mode, dontt split filenames to prefix+name because GNU tar does
not honor it.

- Grr! unterminated buffer string in exclude destination buffer
- fix isfoo() ctype macros to take unsigned char.

Pull up revision 1.54-1.56 via patch (requested by dillo in ticket #507):
Restructure the code to make it more readable. No functional changes.
PR/25934: Dieter Baron: tar and hardlinks with long filenames don't work.
- always put the @LongLink tag on the name, not the long-link name.
- pass in what type of long name record we want to create; one for long-name
or long-link name.
XXX: We should get rid of the switch too.
PR/25934: Dieter Baron: hard links with long names still fail.
As mentioned in the previous commit, the switch statement in the longlink()
needed simplification and it was a bit incorrect. Only depend on the passed
type to determine what kind of gnu longlink to produce. Don't try to deduce
it from the archive file type.
