GES: Questions related to the new "gessrc" element

[David Ing]

It was an excellent suggestion to try it, but it doesn't work.

As a repro, I have an xges file and media files here:
https://drive.google.com/file/d/1rUqC2v55_uLk1J2sEfi1FGyxEfW_RJw_/view?usp=sharing

You can extract the files into a folder, but the xges file has absolute
file paths; so you will need to replace my path with yours.  Mine is
"/home/ding/mess/xges_repro/fedora_30-1.16.0".

You can run a command to prove that this is a valid xges file as follows:

ges-launch-1.0 --load=04.xges

Next you can run the command using playbin, and it just hangs.  It never
plays.

gst-launch-1.0 playbin uri=ges://04.xges

I'm on Fedora 30, and I built 1.16.0 using gst-build.
