In most cases, the pager would have been gone with it's end of the pipe
closed so flushing changes in this case will fail and attempting to write
to the stderr will result in a SIGILL.

Gets the pager commandline from PAGER env. If PAGER env is not set, just
use 'less -FR`.

Same as the usual gst-inspect but written in Rust.

For some reason it doesn't get autogenerated so let's generate it
manually. To avoid conflict with the same method from GObject, let's name
it get_plugin_name().

See gstreamer/gstreamer!31

This allows directly calling them on bins instead of using a global
function.

It can be safely sent between threads as long as all references are in
the same thread.

This adds a usage example for the typefind and multiqueue elements, and dynamic pads.

Gets rid of some unneeded property notification functions in GES

Fixes #151
