Limiting queue disk space does not work, upgrade needed

# lsb_release -rd
Description: Ubuntu 14.04.1 LTS
Release: 14.04
# apt-cache policy rsyslog
rsyslog:
  Installed: 7.4.4-1ubuntu2.3
  Candidate: 7.4.4-1ubuntu2.3
  Version table:
 [...]

When rsyslog is run with a config to save/cache log to disk, e.g when the host that
it is forwarding log to is not responding, it fails to respect the
maxdiskspace parameter. This is a known bug and 7.4.7 of v7-stable has
been released to fix this, see http://www.rsyslog.com/changelog-for-7-4-7-v7-stable/

Config for testing:

global(
  workDirectory="/tmp"
)

module(load="imudp")
module(load="omrelp")

input(type="imudp"
  port="514"
)

action(type="omrelp"
  target="localhost"
  port="2514"
  action.resumeRetryCount="-1"
  queue.saveonshutdown="on"
  queue.type="LinkedList"
  queue.filename="omrelp"

  queue.maxfilesize="100M"
  queue.maxdiskspace="1M"

  queue.checkpointinterval="100"
  queue.highwatermark="10"
)

Then just log more than 1MB of messages to UDP to see that it doesn't
stop at 1MB but just continues forever.

Please upgrade the package to 7.4.7.
