libio: Split patch fixing _IO_wdefault_pbackfail and _IO_wdefault_finish

The patch fixing stream pointer dereferencing in libio should be split and include a copyright header and test description.

Carlos O’Donell requests that Rocket Ma split the patch fixing _IO_wdefault_pbackfail and _IO_wdefault_finish into separate patches. He also asks for a copyright header and a description of the test case to be added.

Technical Tradeoffs

Splitting the patch makes it easier to review and reduces the risk of introducing regressions.
Adding a copyright header and test description ensures compliance with licensing and improves maintainability.
