Summary: cjkcodecs does not initialize type pointer

Initial Comment:
The cjkcodecs code does not initialize the ob_type 
pointer for the 3 type objects it defines.

The following code will illustrate a segmentation fault:

>>> import _codecs_cn
>>> c = _codecs_cn.getcodec('gb2312')
>>> type(c)
Segmentation fault (core dumped)

I have attached a patch which should solve the problem.

I figured Anthony is busy enough. I checked this in since he
said he would.  My bad if you didn't want it in 2.4.2.

Checked in as:
 * Misc/NEWS 1.1193.2.107
 * Modules/cjkcodecs/multibytecodec.c 1.3.2.1

Yes, branch is still frozen. I'll check this in once 2.4.2c1
is out (before 2.4.2 final). I can't get a test case to fail
(rather than just segfault).

Thanks!

Checked in as:
 * Misc/NEWS 1.1374
 * Modules/cjkcodecs/multibytecodec.c 1.4

This needs to be backported.  Anthony is the branch still
frozen?  Feel free to backport this.

I tried to create a test, but it didn't crash.  If someone
can write a test that crashes when running under
regrtest.py, that would be great.
