stringio.c: fix signed integer overflow
* ext/stringio/stringio.c (strio_seek): Avoid signed integer overflow.
It's not harmful in practice here, but is still undefined behavior.
* ext/stringio/stringio.c (strio_extend): Check that the new length does
not exceed LONG_MAX. This fixes the invalid write on the overflow.
* test/stringio/test_stringio.rb (test_write_integer_overflow): Add a
test case for the above fix in strio_extend().
