Build fix after r142540 and r142518

* WebProcess/Plugins/PluginProcessConnectionManager.cpp:
(WebKit::PluginProcessConnectionManager::didReceivePluginProcessConnectionManagerMessageOnConnectionWorkQueue):
This function was added to the header in r142518 but not implemented in that revision.
It wasn't a problem until r142540 started using it.
Add a stub implementation for it.

[HTMLTemplateElement] <template> inside of <head> may not create <body> if EOF is hit
https://bugs.webkit.org/show_bug.cgi?id=109338

Reviewed by Adam Barth.

Source/WebCore:

This patch adds the logic to clear the stack of open elements back to the first <template> when EOF
is hit. This allows a <body> to be generated if the initial <template> was opened inside of <head>.

Tests added to html5lib.
