add Thread safety checker to VxSecVertex
Adding ATLAS static thread safety check on VxSecVertex.
Remove mutable
There were a couple of "const" setters. And a setter can not be const as by definition changes the state ...
- Provide non-const setter for clients to migrate to if applicable
- Mark old methods as
ATLAS_NOT_THREAD_SAFE
so as to allow to be deprecated.
