14f615efd9 If we cannot resolve a path, that probably means that we have not created
directories for that path yet. So, do the check for each component recursively
and succeed if none of the components fall outside our current working
directory.

bc5cd54e43 PR/20228: Simon Burge: pax has problems reading a particular cpio archive
The problem here is that the archive is too short (< 512 bytes). The
buffer routines, try to read at least 512 bytes, even when we try to determine
what format file we have, which is wrong.

15ea30eb09 PR/18759: FUKAUMI Naoki: pax/tar dot-dot handling broken
PR/18840: Frederick Bruckman:  Fix for PR/18663 incomplete pax symlink handling

This patch makes ``--insecure'' do something. Now if ``--insecure''
is not set (the default) we do a realpath(3) in all the pathnames
that we are trying to create and if either realpath fails, or the
path is outside our working directory, we print a warning and die.
This maybe too strict and might fail on valid archives that create
symlinks and directories in the wrong order.

8317fe1276 Add an option --chroot to tar. Causes it to chroot(".") before doing
an extract.  With -h this will cause existing absolute symlinks to be treated
as relative to the current directory.
Helps sysinst handle existing symlinks in the target system.
Remove 'L' from the usage (got spilt into 'h' and 'H' many moons ago)
Add 'S' to usage, and put into correct place in options list.

d980bf3418 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.
