The old code incorrectly calculated visual region for a selection (specified by
QItemSelection object) in case of reordered / swapped rows or columns. It used
the leftmost and rightmost (upmost and downmost for vertical mode) logical
indexes directly. However some middle logical index (in case of reorder) may be
the leftmost or rightmost visual index. In such cases the repainting didn't
work properly. This fix first checks whether reordering / swapping is in use.
If it isn't (ie visual=logical) we use code similar to the old code. Otherwise
the new code scans all selected logical indexes, translates them into visual
ones and gets the correct leftmost and rightmost indexes.

Xcode does not recognize "<Group>" with a capital G, only "<group>" with
a lowercase g. As a result, paths of files within these groups are
calculated incorrectly. For example, dragging any external file into the
Xcode project would result in its leading slash being removed (while
still treated as an absolute path - broken reference). Furthermore, the
dropdown in Xcode displayed the Group location as an invalid string
instead of the correct "Relative to Group". This patch restores correct
behavior.

Give the Windows configureapp the same -pch/-no-pch arguments found in
the Linux configure script.  Using command line arguments to
enable/disable precompiled header use is preferable to mkspec changes.

Make -pch the default for all toolchains.  In particular, this makes
-pch the default for QNX on Windows.  Previously, QNX on Windows had
an implied default of -no-pch.  Precompiled headers are the default
for QNX on Linux; they should also be the default for QNX on Windows.
A 'dictionary["PCH"] = "no"' will need to be added in
Configure::applySpecSpecifics for any toolchain that should default to
-no-pch (none known at this time).

-no-pch is implemented by putting a "CONFIG -= precompile_header"
in qmodule.pri.  This ensures that Qt is built without precompiled
headers (as requested) even if allowing precompiled header use is the
default for the toolchain.

QWindowsXPStylePrivate maintains a list of theme handles for various
style items. The derived class QWindowsVistaStylePrivate had logic
to use a special helper window with the "explorer" window theme set to
obtain the correct treeview arrow branch indicator (arrow shape for Vista as
opposed to '+'/'-' on Windows XP) when creating the "TREEVIEW" theme.
This required calling the helper function
QWindowsVistaStylePrivate::initTreeViewTheming() before
QWindowsXPStylePrivate::createTheme(), which is prone to errors and
initialization order issues.

This could be solved by making QWindowsXPStylePrivate::createTheme()
virtual or similar, but since it the fate of QWindowsXPStylePrivate is most likely
to be merged into QWindowsVistaStylePrivate; it was decided to move
the entire special handling of the Vista treeviews into
QWindowsXPStylePrivate. The existing enumeration value
QWindowsXPStylePrivate::TreeViewTheme is renamed to
QWindowsXPStylePrivate::XpTreeViewTheme and a new value
QWindowsXPStylePrivate::VistaTreeViewTheme is added for which
QWindowsXPStylePrivate::createTheme() invokes the special handling.
This also removes the need to destroy the helper window in unpolish(),
which should save some initializations.
