f485a07454 Add missing thread safety lock assertions in validation.h (Jon Atack)
37af8a20cf Add missing thread safety lock assertions in validation.cpp (Jon Atack)

Pull request description:

  A number of functions in validation.{h,cpp} have a thread safety lock annotation in the declaration but are missing the corresponding run-time lock assertion in the definition.
