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.

5db8977495 Rename main to rust_main to support testing 
On testing, `std` is imported, which defines an own `main` function. Thus `cargo test` fails if there alread exists one non-mangled main.
