patch for Splines.cxx against LO 3.4.0.2

In ODF 1.2 [1] smoothing with splines is concretized. The spec now contains a detailed description, how this splines have to be calculated. The attached patches implement this algorithms. The patches are against LO3.4.0.2

This changes are large, therefore I'll attach the file itself too, so that reading is easier. The solution is tested on WinXp, but need exhaustive testing on other platforms, especially 64bit versions.

I committed the two patches as commit http://cgit.freedesktop.org/libreoffice/calc/commit/?id=f18c69f3f40bf443b59bd006db220267ba5174d0 into LibreOffice master.

RC2 is bit by bit identical with release version, so separate items in the version picker are useless. Changes have been discussed with Michael Meeks.
