e8b3a1fff1 Catch divide error instead of page fault 
The divide error pushes no error code. Thus we avoid stack misalignment (see #184).

8540d3844b Use new x86::segmentation::cs function and merge set_handler and options 
We avoid inline assembly and increase safety (it is no longer possible to set the non-present initilization entries to present).

635f7d3f9d Align section size instead of section start due to #126 
This fixes the problem that GRUB sometimes puts the multiboot info struct between kernel sections if the hole is big enough. This leads to problems since we would try to map the same page twice in that case.
