Firefox 3 XPath changes break dojo.query

[guest]

If you have dojo.query and you want to query another document (say an iframe document):

dojo.query(".foo", iframeDocument);

In firefox 3, you will get: [Exception... "Node cannot be used in a document other than the one in which it was created" code: "4" nsresult: "0x80530004 (NS_ERROR_DOM_WRONG_DOCUMENT_ERR)" location: "​file:///c:/mystuff/ibm/madlib/svn/trunk/lib/dojo-release-1.1.1/dojo/dojo.js.uncompressed.js Line: 5955"] constructor=DOMException code=4 INDEX_SIZE_ERR=1

This is due to a Firefox 3 change (see ​http://weblogs.mozillazine.org/doron/archives/2008/06/documentcreateexpression_chang.html). Dojo is doing:

xpathResult = doc.evaluate(xpath, parent, null, ...

The code needs to use parent's ownerDocument (should parent exist).

(In [14415]) ensure that cross-document xpath-run queries don't bomb out on FF3 due to new security restrictions. Fixes #7075. !strict
