    Bug 699927: don't include operator arrays in execstack output
    
    When we transfer the contents of the execution stack into the array, take the
    extra step of replacing any operator arrays on the stack with the operator
    that reference them.
    
    This prevents the contents of Postscript defined, internal only operators (those
    created with .makeoperator) being exposed via execstack (and thus, via error
    handling).
    
    This necessitates a change in the resource remapping 'resource', which contains
    a procedure which relies on the contents of the operators arrays being present.
    As we already had internal-only variants of countexecstack and execstack
    (.countexecstack and .execstack) - using those, and leaving thier operation
    including the operator arrays means the procedure continues to work correctly.
    
    Both .countexecstack and .execstack are undefined after initialization.
    
    Also, when we store the execstack (or part thereof) for an execstackoverflow
    error, make the same oparray/operator substitution as above for execstack.
