Increases the refcount of the given buffer by one.
Note that the refcount affects the writeability
of buf and its metadata, see gst_buffer_is_writable() and
gst_buffer_is_metadata_writable(). It is
important to note that keeping additional references to
GstBuffer instances can potentially increase the number
of memcpy operations in a pipeline.
