Replace it with std::move(result_val).Unwrap(), or Foo().Unwrap() in
case you already have an rvalue.

This has a huge fallout in terms of needing to fix other files because
all service implementations included that file.

Fixes #2556

* Removes circular dependences (common should not depend on core)

float literals need to have the 'f' prefix.

This makes clang-format useful on those.

Also add a bunch of forgotten transitive includes, which otherwise
prevented compilation.
