hlsdemux http robustness patch 

We had a some issues with hlsdemux in GStreamer 1.2 with regards to http
connectivity. It was with HLS playback on a commodity networking hardware (home
routers, switches etc.) where connections were dropped (connection reset,
etc.). At this point hlsdemux would flag an error and playback was interrupted.
We've introduced a logic to hlsdemux which was responsible for figuring out
what was the error exactly (required changes to souphttpsrc to pass more
details on the error condition) and retrying the download if it was
connectivity issue. For server errors (404 etc) we would forward the error as
expected immediately. For connectivity errors we we're retrying for a fix
number of attempts with a back off time and if connectivity couldn't be
established (fragment couldn't be downloaded) we'd eventually surface an error.

It would be fantastic it adaptivedemux could fix this problem wholesale in 1.5.

I've attached our patches (for 1.2) as a reference. Hope that helps.
