Comment #3 on issue 1056 by pekka.klarck: New keywords `Get Environment
Variables` and `Log Environment Variables` to `OperatingSystem` library.

This issue was updated by revision ce81a7910fa7.
I fixed minor encoding problem with Log Environment Variables by using new
get_env_vars utility function. To make testing the fix easier I changed the
keyword to also return the variables. Also added separate Get Environment
Variables keyword for just getting the variables.
I also updated the documentation of various env var keywords. Janne, could
you review the doc changes and the diff in general?
