[SRU] prompt to change unmodified conf file /etc/cron.d/mailman during upgrade from oneiric to precise

[Jean-Baptiste Lallement]

[IMPACT]
Users are prompted on upgrade from oneiric to precise to update a configuration file which has not been changed.

[TEST CASE]
Start with a fresh oneiric/11.10 install
sudo apt-get install mailman
sudo do-release-upgrade

results in:

Setting up mailman (1:2.1.14-3) ...

Configuration file `/etc/cron.d/mailman'
 ==> File on system created by you or by a script.
 ==> File also in package provided by package maintainer.
   What would you like to do about it ? Your options are:
    Y or I : install the package maintainer's version
    N or O : keep your currently-installed version
      D : show the differences between the versions
      Z : start a shell to examine the situation
 The default action is to keep your current version.
*** mailman (Y/I/N/O/D/Z) [default=N] ?

[REGRESSION POTENTIAL]
The fix is in the maintainer script and simple checks for the existence of the offending file and that its checksum matches a unmodified version - if this is the case it gets removed and replaced by a properly managed one. Minimal but upgrades from lucid should be checked as well.
