Similar to lines (see previous patch), floats from next-in-flow or overflow
frames have probably not been marked dirty (as ReflowInput hasn't dealt with
them when it was constructed), so we need to mark them dirty for proper reflow.
If we don't do that, and they don't fit in the current column, the next column
will only mark its current children dirty, so when pulling back its first
floats from the previous column they will not be reflowed as needed.

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.

We have a fair number of files that have a particular stale version of the MPL
boilerplate. (It was probably originally correct, and then the official
boilerplate changed, and the stale MPL boilerplate continued to propagate via
copypasting from neighboring files into newly-added files.)
This patch updates this stale MPL text (and *only* the MPL text) to the latest
version, which can be found at https://www.mozilla.org/en-US/MPL/headers/ and
https://developer.mozilla.org/en-US/docs/Mozilla/Developer_guide/Coding_Style#Mode_Line

nsReflowStatus::IsEmpty() assertions are added after DISPLAY_REFLOW in the
beginning of the Reflow().
A few Reflow() implementations have Reset() calls at the end which are left
in place by this patch (with an explanatory comment added to each). These
ending Reset()s are only needed for cases where a non-splittable frame
passes its own nsReflowStatus to a child's reflow method. Just in case the
child leaves a "not fully complete" value in the nsReflowStatus, the
non-splittable parent frame must clear out the nsReflowStatus before
returning, so that its own parent doesn't then try to split it.

This is the primary patch in this bug, and makes the performance
improvement that fixes this bug.
The assertion count increase for layout/generic/crashtests/1015844.html
is accompanied by a layout change in the testcase as well. However, I'm
not planning to fix it in this sequence; fundamentally columnsets with
specified heights inside a paginated context (like another columnset) do
not work in any reasonable way, and changing the number of times we
reflow them can change the layout. At least, assuming I didn't lose
something in the process of simplifying the testcase.
ISSUES:
- may make block inside XUL worse in performance by marking dirty more (see subdoc in Firefox UI, or text control innards?)

The new name makes the sense of the condition much clearer. E.g. compare:
NS_WARN_IF_FALSE(!rv.Failed());
with:
NS_WARNING_ASSERTION(!rv.Failed());
The new name also makes it clearer that it only has effect in debug builds,
because that's standard for assertions.
Per spec, the additional leading is added on side of ruby base container, not
ruby container. This could lead to some trivial behavior changes on edge cases.
