Summary: zlib.crc32() not cross-platform

Initial Comment:
The zlib.crc32() function sometimes produces different results for the same input on big and little-endian processors.  Same for zlib.adler32().

sparc64:
>>> import zlib
>>> print zlib.adler32("--------------------------------------------------", 1)
> 3763407051
>>> print zlib.crc32("--------------------------------------------------", 1)
3044228349

i386:
>>> import zlib
>>> print zlib.adler32("--------------------------------------------------", 1)
> -531560245
>>> print zlib.crc32("--------------------------------------------------", 1)
