vaapidecode: use the query virtual methods in 1.4
GstVideoDecoder, the base class of vaapidecode, added support for
pad queries as virtual methods. This patch enables the use of that
support, while keeping support for lower versions of gstreamer.
This patch is important because GstVideoDecoder takes care of other
queries that might be important in the pipeline managing.
v2: 1) rebase to current master
2) fix indentation with gst-indent
3) simplify the patch layout
4) fix the context query
5) initialise the filter to NULL
6) improve the query log message for gst-1.2
