DASH demuxing error "unterminated entity reference" due to ampersand in URL

Commit 7a63da8 broke the DASH demuxer if the manifest contains a BaseURL with an ampersand (&) or other characters that need to be escaped in XML.
This is because the method resolve_content_path calls xmlNodeGetContent, which unescapes the string, and then passes it back to xmlNodeSetContent, which apparently expects an escaped string.
Unfortunately I cannot provide an example MPD, but it should be easy enough to manufacture one by simply adding &v=3 or so to the BaseURL in a simple manifest.
