[issue16367] io.FileIO.readall() is not 64-bit safe on Windows

[STINNER Victor]

New submission from STINNER Victor:

The changeset 374dc910db33 fixed FileIO.readinto(), FileIO.write() and os.write() on Windows for issues #9015, #9611, but FileIO.readall() was not fixed and it has a similar bug.

It uses "int n;" to store the result of read(), so FileIO.readall() may also fail to read a file longer than 2 GB on other platforms.

Attached patch should fix both issues.
