Summary: The first section header does not define a real section. Instead it is used for various elf extensions. This patch skips creation of a section for index 0. This has one furtunate side-effect, in that it allows us to use the section header index as the Section ID (where 0 is also invalid). This way, we can get rid of a lot of spurious +1s in the ObjectFileELF code.
