Avi Kivity d1c049b202 utils: error_injection: remove forward-declared function returning auto ...

Clang dislikes forward-declared functions returning auto, so declare the
type up front. Functions returning auto are a readability problem
anyway.

To solve a circular dependency problem (get_local_injector() ->
error_injection<> -> get_local_injector()), which is further compounded
by problems in using template specializations before they are defined
(which is forbidden), the storage for get_local_injector() was moved
to error_injection<>, and get_local_injector() is just an accessor.
After this, error_injection<> does not depend on get_local_injector().
