[issue24823] ctypes.create_string_buffer does not add NUL if len(init) == size

[Krista Paasonen]

Krista Paasonen added the comment:

Patch containing checking for buffer size, so that NULL value is the last byte as C standard specifies. Raises ValueError exception if initial value does not fit into to the buffer with NULL char.

This should decrease the possibility of creating security issues.
