Bug#47404: dpkg: dpkg does not reconfigure a package when install fails

Package: dpkg

When an error occurs during unpacking, dpkg should unwind all the way back to
step 1.  This means running new-postrm abort-upgrade/abort-install, as well
as old-postinst abort-upgrade.  This is necessary because the old prerm and
the new preinst have both been run during an upgrade.

Here is an example where not doing this may break perl:

$ sudo dpkg -i /mnt/big/debian/repo/dists/potato/main/binary-i386/interpreters/perl-5.005_5.005.03-4.deb
(Reading database ... 74984 files and directories currently installed.)
Preparing to replace perl-5.005 5.005.03-3 (using .../perl-5.005_5.005.03-4.deb) ...
<deleted output from prerm script>
Unpacking replacement perl-5.005 ...
dpkg-deb (subprocess): unexpected end of file in member data in /mnt/big/debian/repo/dists/potato/main/binary-i386/interpreters/perl-5.005_5.005.03-4.deb

dpkg: error processing /mnt/big/debian/repo/dists/potato/main/binary-i386/interpreters/perl-5.005_5.005.03-4.deb (--install):
 subprocess dpkg-deb --fsys-tarfile (EOF) returned error exit status 2
Errors were encountered while processing:

Afterwards, the system did not have an asm link for perl because it was
removed by the prerm script.
