Subject: [PATCH 2/3] Fix deadcode and check return code

1. fstrm-0.6.0/libmy/argv.c:1782: addr_non_null: The address of an object "argv_types" is never null.
2. fstrm-0.6.0/libmy/argv.c:1782: assignment: Assigning: "type_p" = "argv_types".
3. fstrm-0.6.0/libmy/argv.c:1809: notnull: At condition "type_p == NULL", the value of "type_p" cannot be "NULL".
4. fstrm-0.6.0/libmy/argv.c:1809: dead_error_condition: The condition "type_p == NULL" cannot be true.
5. fstrm-0.6.0/libmy/argv.c:1810: dead_error_begin: Execution cannot reach this statement: "(void)fprintf(argv_error_st...".

40. fstrm-0.6.0/libmy/argv.c:2724: check_return: Calling "string_to_value" without checking return value (as is done elsewhere 6 out of 7 times).
