This is an extraction of ArgsManager related functions from util/system into their own common file. Config file related functions are moved to common/config.cpp. The background of this commit is an ongoing effort to decouple the libbitcoinkernel library from the ArgsManager. The ArgsManager belongs into the common library, since the kernel library should not depend on it. See doc/design/libraries.md for more information on this rationale.
