don't show ErrorText for Ign by default

Some distributions (or repositories) do not have as much
"Ign-discipline" as I would like to, so that could be pretty distracting
for our users if enabled by default. It is handy for testcases though.

Git-Dch: Ignore
do not show IP in output of testcases

On travis-ci connect.cc detects a rotation, triggering it store the IP
which is later appended to the error message, which is all nice and
great if we deal with a real server, but in the testcases it just
triggers failures as strings do not match.

Git-Dch: Ignore
fix http-pipeline-messup testcase

The test generates failures if the created deb files have the same size,
so we try a little harder to avoid having the same size for them.

Git-Dch: Ignore
Merge remote-tracking branch 'donkult/feature/acq-trans' into feature/expected-size
Fix http pipeline messup detection

The Maximum-Size protection breaks the http pipeline reorder code
because it relies on that the object got fetched entirely so that
it can compare the hash of the downloaded data. So instead of
stopping when the Maximum-Size of the expected item is reached we
only stop when the maximum size of the biggest item in the queue
is reached. This way the pipeline reoder code keeps working.
