Requests plugin installation and block until the plugins have been
installed or installation has failed.
This function should almost never be used, it only exists for cases where
a non-GLib main loop is running and the user wants to run it in a separate
thread and marshal the result back asynchronously into the main thread
using the other non-GLib main loop. You should almost always use
gst_install_plugins_async() instead of this function.
