LLViewerMedia::clearAllCookies was sending "clear cookies" messages to all plugins and deleting cookie files, but it wasn't clearing the cookies in the central store. It now does all of the above.
LLAgentCamera::cameraOrbitAround() (which had been created from LLAgent:: cameraOrbitAround() when LLAgentCamera was factored out) wasn't correctly processing yaw. Specifically, since gAgent.getFrameAgent() returns by value and not reference, gAgent.getFrameAgent().rotate() was discarding the result of the rotation.
Changed LLAgentCamera::cameraOrbitAround() to use gAgent.yaw() instead, and changed LLAgent::getFrameAgent() to return a const reference instead of a value, which should make the compiler catch errors like this.

Made LLViewerMedia::clearAllCookies() delete the new per-user cookie file (userdir/plugin_cookies.txt) as well as the old one.
Made LLViewerMedia::loadCookieFile() send the clear_cookies message to all loaded plugins.
Added LLPluginCookieStore, which manages the central list of cookies.
New Mac and Windows versions of llqtwebkit, built from the tip of the cookie-api branch on http://bitbucket.org/lindenlab/llqtwebkit/ (currently revision f35a5eab8c2f).
Added "set_cookies" and "cookie_set" messages to the media_browser message class in the plugin API, and made the webkit plugin use them appropriately.
Added methods to LLViewerMedia to read/write the cookie file and add/remove individual cookies.
Added hooks to read/write the cookie file (plugin_cookies.txt) in the same places as the location history (idle_startup() in llstartup.cpp and LLAppViewer::cleanup(), respectively).
