Subject: [PATCH] ensure valid sentinals for gst_structure_get() etc

For GStreamer functions declared with G_GNUC_NULL_TERMINATED,
ie __attribute__((__sentinel__)), gcc will generate a warning if the
last parameter passed to the function is not NULL (where a valid NULL
in this context is defined as zero with any pointer type).

The C callers to such functions within gst-plugins-bad use the C NULL
definition (ie ((void*)0)), which is a valid sentinel.

However the C++ NULL definition (ie 0L), is not a valid sentinel
without an explicit cast to a pointer type.

Upstream-Status: Pending
