<h3>Log Message</h3>
<pre>Merge <a href="http://trac.webkit.org/projects/webkit/changeset/182523">r182523</a> - [GStreamer] extra-headers and keep-alive properties for HTTP source element
https://bugs.webkit.org/show_bug.cgi?id=143480
Reviewed by Carlos Garcia Campos.
Keep the resource loader around when persistent HTTP connection
support is enabled. The keep-alive property is set to false by
default. Also before sending the HTTP request we now check the
contents of the extra-headers GstStructure and set additional
headers based on the structure contents.
Patch inspired by GStreamer's souphttpsrc element.
* platform/graphics/gstreamer/WebKitWebSourceGStreamer.cpp:
(webkit_web_src_init):
(webKitWebSrcFinalize):
(webKitWebSrcSetProperty):
(webKitWebSrcGetProperty):
(webKitWebSrcStop): Clear resource loader only for non-persistent connections.
(webKitWebSrcSetExtraHeader): Utility function to append headers
to an existing request based on a GValue contents.
(webKitWebSrcProcessExtraHeaders): Parse a GValue and set headers
based on its contents.
(webKitWebSrcStart): Extra headers and persistent connection
support. The resource loader is now lazily initialized here.</pre>
