Bug#45299: apt: apt-get doesn't umount CDs

[Enrico Zini <zinie@cs.unibo.it>]

Package: apt
Version: 0.3.12
Severity: normal

If my cdrom is not mounted and I run apt-get to install something from there,
it asks me for the CD, it mounts it, it reads it but it doesn't unmount it.

It would be cleaner if it left the CD in the nearest state it was before
running apt-get; here's what should be the algorithm that seems more clean to
me:

if (the CD was not mounted)
	leave it not mounted
else
	if (the CD was mounted and wasn't changed during apt-get operations)
		leave it mounted
	else
		leave it not mounted
