Line endings confusion

[Andy Seaborne <an...@apache.org>]

Sorry for the commit noise - I managed to convert a lot of files to DOS 
line endings.  This is now fixed.

I still don't know how it happened. In the PR requests I was processing, 
don't list more than a few files but somehow git merge decided to change 
a lot of files. I didn't notice and had pushed them on master.

As history on master must be be rewritten, I had to put in commits to 
fix the line endings.
