fixups: fix param function using a param type mask

- added generic fix_param_type(types_mask, param) function which will try all the types specified in the mask in sequence, until if manages to convert the param to the corresponding type, or it finishes iterating through the types. (e.g. fix_param_types(FPARAM_AVP|FPARAM_SELECT|FPARAM_STR, param)) - changed FPARAM_* order such that more generic types are at the end (types having less chance of failing a conversion, like FPARAM_STR)
