[issue42249] Plistlib cannot create binary Plist file larger than 4GiB

[Serhiy Storchaka]

New submission from Serhiy Storchaka :

Due to a typo plistlib uses at most 32 bits for references and offsets. It will 
fail if try to create a file larger than 4GiB or containing more than 2**32 
unique objects (the latter of course implies the former).
