Score-P User Parameter handling is broken

[AndreasGocht]

The User Parameter handling is broken. E.g. the SCOREP_USER_PARAMETER_STRING expands to:

#define SCOREP_USER_PARAMETER_STRING( name, value ) { \
        static SCOREP_User_ParameterHandle scorep_param = SCOREP_USER_INVALID_PARAMETER; \
        SCOREP_User_ParameterString( &scorep_param, name, value ); }

be aware of the curly brackets!

However, the bindings call the parameter like the following:

void parameter_string(std::string name, std::string value)
{
    static SCOREP_User_ParameterHandle scorep_param = SCOREP_USER_INVALID_PARAMETER;
    SCOREP_User_ParameterString(&scorep_param, name.c_str(), value.c_str());
}

which will result in always the same parameter being used, as scorep_param is only initialised once.
