Android: Remove support for QMAKE_SUPPORTED_ORIENTATIONS

This was created for the iOS port and intended to be cross-platform,
but since then they got cold feet and never added the support.
It makes no sense to only support this on Android. We need to
remove it again and hold off until we can find a proper solution.
Editing the AndroidManifest.xml is the non-cross-platform
solution for this.

When creating QVariant(QPolygonF()) this should be a null variant

The handling of the null QPolygonF case was not correct as it would
always be seen as valid. This ensures it is treated in the same way as
QPolygon when it is in fact null.

[ChangeLog][QtGui][QPolygonF] When a QVariant holds a QPolygonF()
then it will be correctly seen as a null QVariant.

remove broken validation of QMLIMPORTSCANNER

the variable may contain a complex command, so an exists() check is
doomed to failure if the tool is built dynamically.

also, the check is not really necessary: it failing indicates a bug in
the qt build system, and we don't really need to complicate the code to
deal with such corner cases.

Change an addition into a subtraction

This potentially resolves the long-standing warning from GCC:
 assuming signed overflow does not occur when assuming that (X + c) < X
 is always false

GCC prints the warning to warn people that you can't check for overflow
with signed integers by doing that (signed integers don't overflow in
the standard).

If we change this to X < X - c, there's no overflow.

Removed:
- (threads-basics.qdoc) Warning against moveToThread(this): This usage
  came about when people tried to add slots to a QThread subclass. This

- (threads-basics.qdoc) Note on sleep() et al.: They were made public in

- (threads-basics.qdoc) The strategy for managing member variables:

Fix Q_ASSERT(!channels[0].isSocketBusy());

Since commit f30641a7 is has been possible to issue more than one host
lookup request per HttpNetworkConnection. If the result was both an
IPv4 and IPv6 address, and we get a second similar DNS reply, we
end up triggering the assert in startNetworkLayerStateLookup().

This patch splits the InProgress state to HostLookupPending and the state
of trying both IPv4 and IPv6. This makes it possible to ignore any new DNS
replies received after the first succesfull one.
