Make mythuiwebbrowser and mythdownloadmanager share cookies
Seems that Qt went out of their way to make QNetworkCookieJars difficult to
work with. They are not threadsafe (as you can not move them from a QObject
owner in one thread to a QObject owner in another, even if shared). They also
disabled copying them. Argh.
So... Since I already had subclassed it to MythCookieJar anyways, I added the
copy functionality within the subclass. Unfortunately to use this, you need
to use some unsavory static_casts on the pointers to force it to allow you
to effectively copy from the master class to the subclass... and back... Yuk!
So, to share the cookie jar as best we can, when a mythuiwebbrowser starts up,
it takes a copy of the cookie jar that the mythdownloadmanager is holding.
When the mythuiwebbrowser is torn down, it copies the cookie jar back into
the mythdownloadmanager, which then will copy from that temporary jar into its
actual cookie jar at a convenient time in its processing.
The cookie jar in the mythdownloadmanager is protected by a mutex so that there
should be no clobbering at the same time. However, since the MDM could have
updated the jar while the browser was running, there is some possibility that
any cookies the MDM accumulated during that time will be lost on refresh from
