We used to keep both a section and a pointer to the first symbol. The oddity of keeping a section for dynamic symbols is because there is a DT_SYMTAB but no DT_SYMTABZ, so to print the table we have to find the size via a section table. The reason for still keeping a pointer to the first symbol is because we want to be able to print relocation tables even if the section table is missing (it is mandatory only for files used in linking). With this patch we keep just a DynRegionInfo. This then requires changing a few places that were asking for a Elf_Shdr but actually just needed the first symbol. The test change is to delete the program header pointer. Now that we use the information of both DT_SYMTAB and .dynsym, we don't depend on the sh_entsize of .dynsym if we see DT_SYMTAB. Note: It is questionable if it is worth it putting the effort to report broken sh_entsize given that in files with no section table we have to assume it is sizeof(Elf_Sym), but that is for another change.
