This adds support for shadow variables, which allow you to add new "shadow" fields to existing data structures. To allow patches to call the shadow functions in the core module, I had to add a funky hack to use --warn-unresolved-symbols when linking, which allows the patched vmlinux to link with the missing symbols. I also added greps to the log file to ensure that only unresolved symbols to kpatch_shadow_* are allowed. We can remove this hack once the core module gets moved into the kernel tree. Fixes #314.
