Subject: [PATCH 0/2] objtool: Support implicit addend relocations

Future tools that use objtool to process ELF object files may require
reading or even modifying relocations with implicit addends. This
series cleans up the naming of the relocation struct in objtool,
variable names, and function names to be consistent with a more
generic use rather than being specific to those applying explicit
addends.

Changes since RFC [1]:
* Dropped the second patch and rebased on tip objtool/core with
  patch[2] from Sami Tolvanen [Josh Poimboeuf]
* Remade the rename patch with a sed script and added script to
  the commit message to aid backports. [Josh]
* Removed function pointers from last patch. [Josh]
* Added relocation type parameter to elf_create_reloc_section()
  to match pattern with relocation section rebuilding.
