  Log:
  The Q.931 dissector never checked whether the codeset variable was set to a reasonable value or not.
  
  This was problematic and caused crashes since this variable is used as an index into an array where we grab a
  pointer (which is later dereferenced).
  
  Dereferencing that pointer will have surprising effects. Usually crashes.
  
  Update Q.931 to verify sanity of the codeset variable everytime it gets set.
