[xml] xmlschemas.c patch, take 2

[Steve Ball <Steve Ball zveno com>]

The CVS repository already has the uninitialised dictionary bug fixed,
so this patch takes care of the case where the schema document is
supplied by the application and was being freed twice.  With this 
patch, the
schema document is the responsibility of the application and libxml2
will not free it.

I still think that the document should be copied (but only once), since
it will be changed when parsed (whitespace stripped).  However, if the
application cares then it can make its own copy.

Cheers,
Steve Ball
