prepare release 1.0.2
reduce delta from ubuntu
add bash completion for the "apt" command
provide support for debian/apt.conf.$(lsb_release -i -s) vendor specific config files
properly undo CD-ROM mount in all error cases

In bug #740673 various issues in the CD-ROM handling code were
identified, while most the issues ended up being fixed in another way,
the unmounting of the CD-ROM in error cases was not tackled so far.

(The patch was modified by the commiter to apply)
handle pkgnames shorter than modifiers

The bugreport highlights the problem with an empty package name. We fix
this by 'ignoring' these so that it behaves just like "apt-get install".
The deeper problem is that modifier strings can be longer than a package
name in which case the comparison doesn't make sense, so don't compare
then. Was not noticed so far as all modifiers are of length 1, so the
only package name shorter than this is in fact the empty package name.

add vendor information for BlankOn

Modified by commiter to not publicily export the codename (as the
manpages do not use it that way) and removing the included additional
derives logic as it was not working (the link always exists at that
point) and isn't needed as we do the special casing for debian mainly
because it would shallow all distributions otherwise.
(similar, but not that strong for ubuntu)

Closes: 743595
add a README for vendor information
remove outdated README.MultiArch

Debian wheezy shipped MultiArch to the masses and the predictions
remained true in sofar as little changes in apt itself and many
other frontends were needed compared to the fallout if done differently.

The info included is this file is therefore no longer current and adds
no useful information anymore, so we can drop it for good.
build http request in a stringstream

beside reducing code a bit, it avoids oddball problems while building
the string and doesn't trigger static analyse warnings.
remove unused duplicated acqprogress.{cc,h} files

Those files are in apt-private and used from there.

Git-Dch: Ignore
enforce LFS for partial files in https range requests
fix FileFd::Size bitswap on big-endian architectures

gzip only gives us 32bit of size, storing it in a 64bit container and
doing a 32bit flip on it has therefore unintended results.
So we just go with a exact size container and let the flipping be handled
by eglibc provided le32toh removing our #ifdef machinery.
