Mixed line endings cause problems when exporting patches with git-format-patch and then trying to "git am" a patch with mixed and non-matching line endings. In such a situation git will fail to apply the patch. This commit runs the dos2unix tools on the remaining files with CRLF (\r\n) line endings to convert them to line-feeds (\n) only. Files that are Windows specific like *.vcxproj and *.props files were not converted. Closes: #3073
