Directory.Build.shared.props

<Project>

  <!--
    The build settings every project in the solution shares, production and test alike. MSBuild stops at
    the nearest Directory.Build.props, so src/Directory.Build.props and tests/Directory.Build.props each
    import this file and add only what is particular to them.

    Two entries under WarningsAsErrors fail a build: nullable flags a possible null dereference or a
    broken nullability contract, and CA2016 flags a method that holds a CancellationToken yet calls an
    overload that would take it without passing it on, which is the shape of #219. Everything else stays
    a warning.
