Potential memory leaks in JsonArray.cpp

[GoogleCodeExporter]

What steps will reproduce the problem?
There is a lot of code of the form

    CJsonString* string = new (ELeave) CJsonString; 
    string->SetIntL(aValue);
    iElements.AppendL( string );

If either of SetIntL or AppendL leaves, 'string' will be leaked.
The code above should be written as:

    CJsonString* string = new (ELeave) CJsonString; 
        CleanupStack::PushL(string);
    string->SetIntL(aValue);
    iElements.AppendL( string );
        CleanupStack::Pop(string); // Don't use PopAndDestroy because iElements acquires ownership of 'string'
