Cleanup environment related files

This patch series cleans up environment related files in terms of checkpatch and other coding style issues. It is based on Mon, 7 Nov 2011 Wolfgang's master.

There are several warnings/errors left, mostly because I don't think we need those solved or I can't choose the right solution.

Probably, there will be several conflict with the recent patches on the list, so once all issues are fixed,
I can rebase this patch set on top of the most recent master.

Thanks to all reviewers :-)
