XCB: silence warnings about possibly undefined shifts

The code shifts "1" by a uint32 number. If that number is >= 32,
we're triggering undefined behavior, and Coverity rightfully complains
about that. Add some asserts to silence those warnings.

Initialize QFileSystemMetaData::size_ data member

There's a code path which reads that member before it got anything
assigned to it, triggering undefined behavior.

The code path goes as follows:

1. an instance is created in QFSFileEngineIterator::advance
2. the instance is passed to QFileSystemIterator::advance, which fills in
   only some members (not size_)
3. the instance is passed to QFileInfoPrivate which does a deep copy,
   reading an uninitialized size_

QMacStyle: save context state before changing to avoid crash

qt_drawFocusRingOnPath was saving the graphics state after setting
a new context. This leads to zombie NSBitmapGraphicsContext access
with QFileDialog.

QAbstractItemView: fix CTRL+A select all behavior

The check for Qt::Key_A to handle selectAll was changed to directly
compare to QKeySequence::SelectAll as this will only match Ctrl. The
former implementation also triggered when e.g. Shift was pressed.
Added a check that selectAll is only called when selection is not
disabled, i.e. selectionMode=NoSelection.

Added a unit test for selectAll().

QMacStyle: Fix QSlider appearance on Yosemite

First, we adjust the min and max positions, which HITheme has been
unable to render properly for years. This involves separating the
knob and track rendering. Also, on Yosemite, the tickmarks-less
slider shows a blue progress fill in the track, on the knob's left
side. Finaly, and this is valid for all versions, the tickmarks are
being drawn before the knob (or the whole slider for OS X versions
before 10.10)
