Sebastian Dröge bd6e1a9f70 souphttpsrc: Always abort the session once its last user is gone 
And wait until there are no pending GSources on the main context anymore
afterwards.

/**
* SECTION:element-souphttpsrc
* @title: souphttpsrc
*
* This plugin reads data from a remote location specified by a URI.
* Supported protocols are 'http', 'https'.
*
* An HTTP proxy must be specified by its URL.
* If the "http_proxy" environment variable is set, its value is used.
* If built with libsoup's GNOME integration features, the GNOME proxy
* configuration will be used, or failing that, proxy autodetection.
* The #GstSoupHTTPSrc:proxy property can be used to override the default.
*
* In case the #GstSoupHTTPSrc:iradio-mode property is set and the location is
* an HTTP resource, souphttpsrc will send special Icecast HTTP headers to the
* server to request additional Icecast meta-information.
* If the server is not an Icecast server, it will behave as if the
* #GstSoupHTTPSrc:iradio-mode property were not set. If it is, souphttpsrc will
* output data with a media type of application/x-icy, in which case you will
* need to use the #GstICYDemux element as follow-up element to extract the Icecast
* metadata and to determine the underlying media type.
*
* ## Example launch line
* |[
* gst-launch-1.0 -v souphttpsrc location=https://some.server.org/index.html
* ! filesink location=/home/joe/server.html
* ]| The above pipeline reads a web page from a server using the HTTPS protocol
* and writes it to a local file.
* |[
* gst-launch-1.0 -v souphttpsrc user-agent="FooPlayer 0.99 beta"
* automatic-redirect=false proxy=http://proxy.intranet.local:8080
* location=http://music.foobar.com/demo.mp3 ! mpgaudioparse
* ! mpg123audiodec ! audioconvert ! audioresample ! autoaudiosink
* ]| The above pipeline will read and decode and play an mp3 file from a
* web server using the HTTP protocol. If the server sends redirects,
* the request fails instead of following the redirect. The specified
* HTTP proxy server is used. The User-Agent HTTP request header
* is set to a custom string instead of "GStreamer souphttpsrc."
* |[
* gst-launch-1.0 -v souphttpsrc location=http://10.11.12.13/mjpeg
* do-timestamp=true ! multipartdemux
* ! image/jpeg,width=640,height=480 ! matroskamux
* ! filesink location=mjpeg.mkv
* ]| The above pipeline reads a motion JPEG stream from an IP camera
* using the HTTP protocol, encoded as mime/multipart image/jpeg
* parts, and writes a Matroska motion JPEG file. The width and
* height properties are set in the caps to provide the Matroska
* multiplexer with the information to set this in the header.
* Timestamps are set on the buffers as they arrive from the camera.
* These are used by the mime/multipart demultiplexer to emit timestamps
* on the JPEG-encoded video frame buffers. This allows the Matroska
* multiplexer to timestamp the frames in the resulting file.
*
