[xml] Warnings you might want to fix

[Mike Hommey <mh glandium org>]

Hi,

Here are the warnings I get while building libxml2 2.6.19 with -Wall
flag, you might want to fix these, or at least, some.

PS: I'm not sure the generated libxml.c file in the python directory
matches the one in the tarball, so line numbers might not be accurate.
