dashdemux: Properly detect presence of xml attributes

Convert all xml attribute/content parsing functions to return a
boolean value indicating whether or not the attribute/content was
present.  We need this finer-grained control in order to properly
implement the inheritance policies described in the spec

Also fixed several memory leak conditions when handling errors in
the xml attribute/content parsing functions.
