[New-bugs-announce] [issue27438] Refactot simple iterators implementation

[Serhiy Storchaka]

New submission from Serhiy Storchaka:

The implementation of iterators for str, bytes, bytearray, tuple and list is virtually the same. Proposed patch moves common code to the template file iterlib.h and parametrizes it with few macros.

The patch decreases the number of source lines by 600.
