QNetworkConfigurationManager creates the engines loaded from plugins
as objects in the main thread.
If a QNetworkConfigurationManager instance is created in a worker thread
without any instance previously existing in the main thread, then it
is uninitialised until the main thread has run.
This causes allConfigurations() to return an empty list if called
immediately after instantiation, for example.
This fix initialises the plugins using blocking queued connections,
which causes the worker thread to block until the initialisation function
has been called in the context of the main thread.
Deadlock is possible if the main thread is for some reason waiting on the
worker thread, but it will not deadlock on QNetworkConfigurationManager's
mutex.
If this is a problem for an application, it should use
QNetworkConfigurationManager from the main thread first to preload the
plugins.

In Qt 4.7, http network requests are assigned to http connection
channels before connecting the channel.
In Qt 4.8, channels are connected "blind" as this gives a performance
improvement in certain circumstances.
On the assumption that User-Agent should be the same for all the
requests being sent to the server in a given burst, we use the first
queued request to set the user agent for a http proxy.

Due to architecture changes in Qt 4.8, clearing the proxy before the
request is complete causes the http connection to not use any proxy.
The issue is that the proxy isn't resolved until after the bearer has
been started (which is correct in the general case, as system proxy
is unknown until that time).
Also increased the test's timeout from 1 second to 15, as starting a
bearer can be slow.

Some proxies can discriminate based on the User-Agent when sent a
CONNECT command for establishing a HTTPS connection.
With this change, if the User-Agent header is set in the QNetworkRequest
then it will be passed to the http socket engine for use in the connect
command sent to the proxy.
As before, "Mozilla/5.0" will be used by default when no user agent
has been set.

The backend was never started when compiled without bearer management,
now it is.

Delayed the resolving of the proxy until the backend is being started.
This is because the proxy settings are not known until after
QNetworkAccessManager has brought the network online using
QNetworkSession.
On Nokia's symbian3 phones, the default network configuration is a
service network containing a list of access points in priority order.
For a typical user, this will include one or more WLAN networks and a
cellular network - each of which can have different proxy settings.

When Qt is compiled with bearer management support, the network
configuration can be included as a parameter in QNetworkProxyQuery.
This allows QNetworkProxyFactory::systemProxyForQuery to get the right
proxy setting for a specific network. For example a mobile phone could
have network configurations for home WLAN, work WLAN and 3G data
access points, each with different proxy configurations.

When the matrix has an non-affine transformation, the text will have to
be rendered using the default path-renderer. This means going through
the drawTextItem() path (since drawStaticText() has no support for those
transformations) and it also means not pre-transforming the coordinates,
since the default implementation of drawTextItem() supports
transformations.
