Rename some list heads to distinguish them from hash node heads, which are added later in the patch series. Also rename the get_*() functions to add_*(), which is more descriptive: they "add" data to the objtool_file struct. Also rename rodata_rela and text_rela to be clearer: - text_rela refers to a rela entry in .rela.text. - rodata_rela refers to a rela entry in .rela.rodata.
