[issue6239] c_char_p return value returns string, not bytes

[Georg Brandl]

New submission from Georg Brandl <georg at python.org>:

If you assign a function a restype of c_char_p, you get back a Unicode
string, but you should get a bytes object.

>>> from ctypes import *
>>> strchr = cdll['libc.so.6'].strchr
>>> strchr.restype = c_char_p
>>> strchr.argtypes = [c_char_p, c_char]
>>> strchr(b'abcde', b'd')
'de'
