dwke - Skip section if Section dir is inaccessible.

detect_well_known_errors() was crashing during the daily run on days
when a section was added (due to a return with the wrong number of
arguments).
p-s: skip upgrade tests involving downgrades

Report these tests as untestable.
Downgrades 'happen' e.g. in stable2bpo2testing if the version in backports
is (temporarily) newer than testing.

Workaround #709372 and ignore broken symlinks found by adequate.
p-r: switch from python-rpy to python-rpy2

python-rpy is obsolete and planned to be removed

use a noninteractive png grDevice to avoid requiring X access

based on an initial patch from Dave Steele

p-m: use timeout to prevent master from getting stuck

It is possible that the master gets stuck waiting for a response from
the slave or while fetching a Packages file - this is usually related
to network errors.
Terminate the master instance after 15 minutes to prevent a section
from being locked forever, requiring manual interaction to cleanup.
