Review request for Calligra, Lassi Nieminen and Jarosław Staniek.


Repository: calligra


Description
-------

This patch is a refactoring of how charts are handled in the filters. There are two purposes of it:
1. Make it sane in general. As it was before, the various filters where reaching into each other for bits and pieces of code, and the naming was strange in places. There was also a strange mixture of MS binary and MSOOXML concepts in the same files.
2. To prepare for the next step which is sharing storage classes for charts between the filters and the chart shape. As it is now, many defines and both loading and saving is duplicated all over Calligra. This is not the way we want things to be.

There is hardly any new code in here, only rearranging of what was already there. Here is a summary (everything happens inside the filters/ tree):
 - Factor out common parts and move them to libodf2/charts
 - Factor out the parts common to MS handling and move them to libmso/
 - Move common parts within the ooxml filters from the xlsx tree to libmsooxml/
 - Move things that only have to do with MS binary parts to libmso/
 - Rename the vaguely named namespace "Charting" to "KoChart"
 - Rename ChartExport to KoOdfChartWriter, which should be clearer
 - Make the filters use and link to the libraries instead of each other

Testing
-------

There is no new code at all, only rearrangement. But all the filters work as expected.


Thanks,

Inge Wallin
