[xml] _private in xmlNs?

Hello Daniel,

is it possible to add _private to xmlNs too ?
This would greatly help in implementing DOM wrapper for namespace
declaration nodes; otherwise I have to keep a map of xmlNs node and its
wrapper object.

I suggest doing it by the following patch - "_private" is made the first
member, and "next" is moved to the end of the struct, so that the layout is
as similar as possible to structure of other nodes:
