The returned list of diffs aims to simulate how a file system diff would
look before and after writing the sources list files.

The old method left settings in the environment. The new method takes
care of clearing them after use. In this module, the old method was
also setting the environment too late to affect all the command line
tools which lead to a bug.

This mirrors a nearly identical change made to apt_repository.py.
Also removes the use of apt-get --force-yes as it can be dangerous
and should not be necessary (apt_repository.py does not use it).
Repeating the explanation from the apt_respository change below:
Since use_unsafe_shell is suspicious from a security point
of view (or it wouldn't be unsafe), the less we have, the less
code we have to thoroughly inspect for a security audit.
In this case, the '&&' can be replaced by doing 2 calls to run_command.
Since there is no shell escape of the password parameter, a password with
a single quote (or even worst, a single quote and a pipe) could have
unattended consequences. Also, the less we use use_unsafe_shell=True, the
better.
On systems with restrictive umasks, the pip module won't allow you to
install pip packages that are usable by everyone on the system. This
commit adds a umask option to optionally override the umask on a
per-package basis.
Without this change, some trouble may occur when "deb" parameter
is used as env vars controlling dpkg are not set. For example,
installing a package that requires user input will never end since
DEBIAN_FRONTEND=noninteractive is not set.
So export env vars in APT_ENV_VARS before run dpkg, like in cases
using apt-get/aptitude.
* This keeps us from hitting bugs in repoquery/yum plugins in certain
instances (#2559).
* The previous is also a small performance boost
* Also in is_installed(), when using the yum API, return if we detect
a package name has been installed. We don't need to also check
virtual provides in that case. This is another small performance
boost.
* Sort the list of packages returned by the list parameter.
