sip: media-pipeline: Use debug macros to allow graphing pipelines

Browse source 
If the environment variable GST_DEBUG_DUMP_DOT_DIR is set, a graph of the send
and receive pipelines will be written to disk.

To generate a png from the exported dot files graphviz can be used like this:

`dot -Tpng -oimage.png graph.dot`
