Bitcoin uses underscore in util/translation.h for translatable strings but underscores are also a placeholder used in multiple languages, incl. C++. The next commit will be introducing backports, one of them will be placing util/translation.h into validation.h, which is a header used by Dash-specific code. This causes a conflict between the normal usage of underscore as a placeholder and Bitcoin's usage of it as a function name, which is reported by the Dash-specific linter. We need to exclude shadowing warnings from the linter to account for this.
