Review request for Calligra and Camilla Boemann.


Changes
-------

Fix the code formatting issues


Repository: calligra


Description
-------

This patch refactors a bit the KoTextLayoutRootAreaProvider.
It extends the provideNext call by adding a constraints structure.
This structure contains so far the masterPageName and the page
number of the requested new rootArea.
This way, the provider don't have to sneak in layout specific data.
It also adds a way for KoTextLayoutRootAreaProvider to help the
layout and fix inserting a new page (by adding lines to a paragraph
for instance) before a page break changing the page style.

Some more explanations regarding this bug :
- Page 1, style AAA
* page break, requesting style BBB
- Page 2, style BBB

If you add more data to the page 1, then dynamically the layout should
do :
- Page 1, style AAA
- Page 2, style AAA
* page break, requesting style BBB
- Page 3, style BBB

But the layout did recycle the page 2, leading to :
- Page 1, style AAA
- Page 2, style BBB
* page break, requesting style BBB
- Page 3, style BBB

Reloading the document leads to a correct layout.

Testing
-------

A simple document with page styles (changing the background color to help speed up the development) now doesn't exhibit the wrong layout behaviour.


Thanks,
