Summary: gzip.GzipFile to accept stream as fileobj.

Initial Comment:
When gzip.GzipFile is initialized with a fileobj which
does not have
tell() and seek() methods (non-rewinding stream) it throws
exception. The interesting thing is that it doesn't
have to. The
following patch updates gzip.py to allow any stream
with just a
read() method to be used. This is helpful if you want
to be able to
do something like:
gzip.GzipFile(fileobj=urllib.urlopen("file:///README.gz")).readlines()
or use GzipFile with sys.stdin stream.

But keep in mind that seek() and rewind() methond of
the GzipFile()
won't for such stream even with the patch.

Igor
