Evangelos Ribeiro Tzaras 563ceb770c media-pipeline: Dump dot graph without GST_DEBUG_DUMP_DOT_DIR set ...

gst_debug_bin_to_dot_file() NOOPs if GStreamer was initialized without
the enviroment variable GST_DEBUG_DUMP_DOT_DIR.

If SIGUSR2 was signalled we want to have a dot file dumped no matter
what. Functions for asynchronously writing the graph as obtained by
gst_debug_bin_dot_data() to a temporary file and print the path to
stdout.

Note: Usage of GST_DEBUG_BIN_DOT_FILE() on pipeline state change is left
as is, because we don't want to dump graphs for every change on every
pipeline.
