Adds one of the missing pieces of the QWebFrame and QWebView APIs.
Unlike the QtWebKit version this only fetches the favicon URL, and not
the icon. This is because we do not want to implement an icon database,
and that the icon would be loaded asynchronous anyway, bringing no
guarantee to be a valid icon/image yet.

Chromium also only supports frame values, while a complete support of
the interface would require also supporting this xPath to point to

I initially misintepreted the meaning of the enum, assuming that it
meant that the window should possibly be blocked. The user_gesture
parameter in WebContentsDelegate::AddNewContents is actually doing
this, while the popup disposition means that JavaScript requested
the window to be opened without one of the standard decoration (i.e.
status bar, menu bar, tool bar, etc.).

Update the QtQuick API to reflect this, renaming the "isPopup"
parameter to a more familiar "isUserInitiated".

The popup disposition is named "dialog" to match the previous
QWebPage::WebModalDialog enum.

This does uses logic taken from Chromium's state save and restore
code. The history version is incremented from the same method in
QtWebKit in cases where the application would try loading a stream
from a previous version using QtWebKit.

In all cases where Chromium does a restore of a serialized history,
it does so on a fresh WebContents instance, thus we must do the same
and some of the initialization code has to be updated.

This mainly remove the use of the LoadingStateChanged callback, which
is tied to DidStartLoading and DidStopLoading.
Those signals are handled from the browser process side, also wrapping
the time where the render process is initialized. We can't rely on
those signals for loadStarted, but afterward rely on the Blink loader
for loadFinished. We must use the same source for both.

Instead only rely on Blink callbacks ultimately related to network
events. This gives us a behavior closer to QtWebKit.

The major compromise that this forces us to to accept is that
loadStarted is now triggered asynchronously. This will basically break
anything expecting loadStarted to be emitted synchronously from the
load method.

This also adjust autotests to get a few more passing.

This allows handling calls that would be signaled by QNetworkAccessManager

This pulls QtNetwork as a dependency of the QtWebEngineWidgets module
to be able to use QAuthenticator, but isn't required otherwise.

Only the request URL is available in the case of HTTP authentication
(no access to HTTP request headers that the QNetworkReply would allow)
and only the proxy host name in the case case of proxy authentication.

This keeps the API synchronous the same way, as QtWebKit did, in
favor of source compatibility at the cost of requiring a modal
dialog, even though the implementation doesn't require it.

or requiring a different hash table just to please the type system.

This does so by managing the ref-counted callback pointers directly

requires a different type for each different callback pointer type.

The ref-counting, construction and destruction is managed through

Also pass the callback result through WebContentsAdapterClient using

already allow passing a callback functor, to use a consisten way
of carrying back the result to the top API layer.
