Summary: It's always annoying to find a header does not include its own dependencies and only works when included after other includes. This change adds `make check-headers` which validates that each header can be included at the top of a file. Some headers are excluded e.g. because of platform or external dependencies. rocksdb_namespace.h had to be re-worked slightly to enable checking for failure to include it. (ROCKSDB_NAMESPACE is a valid namespace name.) Fixes mostly involve adding and cleaning up #includes, but for FileTraceWriter, a constructor was out-of-lined to make a forward declaration sufficient. This check is not currently run with `make check` but is added to CircleCI build-linux-unity since that one is already relatively fast.
