Summary: send/recv SEGMENT_SIZE should be used more in socketmodule

Initial Comment:
socketmodule.c contains a SEGMENT_SIZE define that is
used to limit the send/recv buffer size on VMS.

But IMO there are two problems:
1) it should also be used on windows, because windows
doesn't like a large send/recv buffer either,
2) it should be used in more places: at least sendall,
but perhaps also recvfrom, sendto

ad 1: see also this bug: http://www.python.org/sf/853507

Btw: I'm not too experienced with Win32 programming and so I
don't have a very good argumentation for the buffer size issue
on this platform. If there is somebody with better understanding
of the issues involved here, please advise.
(it's just empirical knowledge that I have that leads me to
believe that win32's tcp implementation suffers from similar
recv/send size problems as VMS does-- for which a special
case was made in the code)
