Daniel Holbert 680815cd6e Bug 1412346 part 5: (automated patch) Switch a bunch of C++ files in layout to use our standard mode lines. r=jfkthame
This patch was generated automatically by the "modeline.py" script, available
here: https://github.com/amccreight/moz-source-tools/blob/master/modeline.py

For every file that is modified in this patch, the changes are as follows:
 (1) The patch changes the file to use the exact C++ mode lines from the
     Mozilla coding style guide, available here:
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line

 (2) The patch deletes any blank lines between the mode line & the MPL
     boilerplate comment.

 (3) If the file previously had the mode lines and MPL boilerplate in a
     single contiguous C++ comment, then the patch splits them into
     separate C++ comments, to match the boilerplate in the coding style.
