kpatch-elf: introduce a common kpatch-elf and logging interface Introduce a common kpatch elf api by moving all functions and struct declarations related to manipulating kpatch_elf objects from create-diff-object to kpatch-elf.{h,c}. Move logging macros to a separate file log.h, and have kpatch-elf.h include it. These changes will generalize the kpatch-elf and logging api and make it available to other kpatch-build tools.

create-diff-object: use errx() instead of err() Otherwise on recent distros it appends the errno to the error message, like: create-diff-object: ERROR: x86.o: kpatch_regenerate_special_section: 2633: Found 1 unsupported static call(s) in the patched code. Use KPATCH_STATIC_CALL() instead.: Success which is not what we want in most cases. Signed-off-by: Josh Poimboeuf <jpoimboe@redhat.com>
