Purpose: MapScript exceptions
Author: Umberto Unicoletti, unicoletti@prometeo.it

Sean Gillies, sgillies@frii.com
Tamas Szekeres, szekerest@gmail.com
Note: Python exceptions are in mapscript/python
C# exceptions are redefinied in mapscript/csharp
This implementation truncates the error message length
to MAX_ERROR_LEN since SWIG_exception does not allow
to free memory allocated on the heap easily (szekerest)
