This patch is a pre-requisite for moving implementation of llvm-objcopy into
separate library(http://lists.llvm.org/pipermail/llvm-dev/2020-September/145075.html).
It allows to redefine error handling. I.e. it makes possible to change the way
how errors are displayed by library user. It creates a class ErrorReporter
(llvm-objcopy/Error.h) which could report recoverable error, unrecoverable error,
warning. If necessary all handlers could be redefined.
