tests: Add a test harness for testing discoverer

The harness expects a tests/media directory with a file list in the
format described in a comment at the top of the harness. The means to
set up the media directory will come in a subsequent commit.

+# Usage:
+#   test-discoverer.sh <file_list> <media_dir> <extra_args ...>
+#
+# <file_list> is a CSV file in the format:
+#   path_name,profile_name,mime_type
+#
+# Path names in the list are relative to <media_dir>
+#
+# <extra_args> are passed on to gupnp-dlna-info
+#
+# The first two parameters can be passed as the FILE_LIST and MEDIA_DIR
+# environment variable as well (but you must either pass both as env vars or
+# both on the command line).
