BB select(): move special select method to qcore_unix_p.h

... and make it independent of QProcess, because we want to use it
from QtNetwork as well.
In addition, move select_msecs() to qcore_unix_p.h as well and rename
it to qt_select_msecs().

XCB plugin: query screen resources without _current

xcb_randr_get_screen_resources() and xcb_randr_get_screen_resources_current()
do basically the same, but for one case: if nothing has queried these
information ever before. So if an application is the very first client ever
to connect to an X server it may just return nothing. A call to
xcb_randr_get_screen_info_reply() will then cause the X server to allocate the
needed information and send an update notification, resulting in a second
QXcbScreen being created, but the other one is still around and probably used.

The behavior I observed with a simple test application was that the application
was not visible on the screen when it was the first client ever on the X
server. Killing the application and starting it again made it work just fine.

Repaint widgets on screen change.

Add a screenChanged handler slot to QWidgetWindow,
which calls markDirty() on the backing store with
the BufferInvalid and UpdateNow flags set.

Update CocoaBackingStore to create a new buffer on
window devicePixelRatio change. Use the
QCocoaWindow::devicePixelRatio() implementation instead
of a duplicate implementation in the backing store.

The plan is to replace this implementation with one
based on QUpdateWindowRequestEvent for Qt 5.4
