the primary purpose is making env var prepend mode work for unset
variables on windows. this is achieved by using a conditional and delayed
variable expansion. however, the latter is disabled by default and can
be locally enabled only in batch files. therefore, write wrapper scripts
and substitute them for the actual commands. we do this also on unix,
both for consistency and simply because the commands look much less
confusing.
this change is slightly backwards-incompatible, as invoking
qtAddToolEnv() multiple times on the same command will now make a total
mess. also, invoking it on a command that contains 'make' macro
expansions isn't a good idea, so testcase.prf needed an adjustment. the
function is an undocumented internal, so Nobody Should Care (TM).

Render-to-texture widgets that are native children may have a non-zero
offset telling the position within the top-level widget. The size is
usually different (smaller) than the tlw's size as well.
An unfortunate optimization attempt led to ignoring the size for native
children with offset (0, 0). This resulted in interesting rendering
artifacts whenever such widgets were placed in the top-left corner of
the toplevel. This is now corrected.

GCC 5.3's undefined-behavior sanitizer checks that the
declared type of the object is a base class of the
dynamic type of the object on each access to a member
of a class type.
It therefore requires the typeinfo for these types,
which for polymorphic types is emitted in the TU where
the vtable is emitted, too.
QFileDialogPrivate is a polymorphic non-exported class,
so this failed at link-time. Ditto for the other cases.
Fix by autotest-exporting the classs.
Also, where applicable, de-inline the dtors, so the
vtable (and typeinfo) are pinned to one TU, and the
ctor, just because it's the correct thing to do.

If we select XInput events, then when the mouse is clicked, there will
not be a fallback to a core pointer event. But a typical Qt application
doesn't own the root window. If the window manager (such as OpenBox,
Awesome or fvwm) relies on receiving core pointer click events, e.g.
to show a desktop menu, then each time a device is hotplugged while a
Qt application is running, we would select XI2 events and thereby
prevent the window manager from receiving them.
QDesktopWidget's native window is added to m_mapper, even when
it isn't mapped. Then after hotplugging there's a hierarchy event,
and that calls xi2Select for every window in m_mapper. The assumption
with this patch is that the root window does need to be in m_mapper
in case the QDesktopWidget is shown (that was done already in Qt 5.1:
fca94fa5ed), but xi2Select must avoid
selecting XI2 events on it to fix this bug.
