Make QtDBus compile without libdbus-1 headers, if dlopening

Most of QtDBus already needs very little from libdus-1, so create an
extra header containing the minimum API we actually need.

One large advantage of this solution is that now QtDBus can always be
enabled, even if the system doesn't have libdbus-1 installed. This is
interesting on OS X, where libdbus-1 is often installed by Homebrew or
MacPorts, which may include extra libraries we don't want in our
packaging.

FSEvents file system watcher: Do not watch whole parent hierarchies.

Unfortunately the FSEvents implementation for watching parent
hierarchies has the major flaw, that watching a path will then
create watches for the whole parent hierarchy even if that
hierarchy is already watched. Watching /A/B/C and /A/B/D will
create two watches each for /A and /A/B. This leads to an explosion
of open file handles.
Luckily we do not need to watch the parent hierarchy since this
is not a supported usecase of QFileSystemWatcher anyhow, so just don't
do it.

QOpenGLFramebufferObject: pass sized format also with dynamic GL

The GL_RGBA8_OES define is not in scope for dynamic OpenGL builds, so
pass in GL_RGBA8 instead (it is defined as the same value, 0x8058) when
in ES mode. The functionality check already ensures the extension is
available, so the ifdef guards can be removed.

This fixes default multisampled FBO creation under ANGLE when using
-opengl dynamic.

for instance get black as both the base color and text

Draw the accessibility focus rectangle properly

Previously, the accessibility focus rectangle was only visible when it
overlapped with the m_editText View of QtActivityDelegate. The reason for
this is not completely verified, but this is the most likely reason:

  * The SurfaceView and QtLayout (ViewGroup) does not do any drawing
    themselves. Due to this their default value of the View::willNotDraw
    property is true.  Because of this Android might assume there is no
    content for the focus indicator to surround. (This was verified with
    setting the willNotDraw property to false on the accessibility view);

  * Another possible reason could be that overlays does not work for
    SurfaceView. It is documented that overlays does not work for
    SurfaceViews, so therefore it tried to use the overlay of another
    view. For some reason it picked the m_editText overlay instead of the
    QtLayout overlay.

    See here about overlay:
    http://developer.android.com/reference/android/view/View.html#getOverlay()

The solution is to add another View that covers the whole screen, which
will be used solely by android to draw the accessibility focus indicator.

In addition, we change the QtAccessibilityDelegate to no longer have the
SurfaceView as a host, but have the m_accView as a
host (the host can be freely changed, since all accessibility nodes are
virtualized through the delegate anyway)

For the record, this will be the current ordering of views in QtLayout:
(back-to-front order):
                                Qty     Default Qty
* Surface View(s)               >= 1    1
* Accessibility View            == 1    1
* Native View(s)                >= 0    1
* m_editText View               == 1    1
where the m_editText migth be interleaved among the Native Views.

QColumnView: don't set an invalid index as the current one

When any item in a QColumnView gets selected, the next column gets
normally set to show the children of that index. When we are on a leaf
of a tree model, the next column will have an invalid root index, yet
we set that root index as the "current index" for the current column.

Due to the special handling for invalid indexes in
QAbstractItemView::setCurrentIndex, this ends up breaking the current
item AND the current selection in that column. Further clicks inside
the column for instance trigger the entire column (up to the clicked
index) to get selected, because of that broken first setCurrentIndex.

The simple fix is to stop doing that when the next column has
an invalid root index.

Android: Enable -fno-builtin-memmove in arm builds

On some devices, a miscompilation of libc.so has caused it to
return the wrong value. Instead of returning the dest pointer,
it returns dest + n. When compiling with optimizations turned
on, gcc may use this return value for subsequent accesses to
dest after the memmove() call, causing memory corruption.

This caused problems e.g. in QVector::prepend() which would
overwrite the whole vector with the new value.

Setting -fno-builtin-memmove disables the optimization and
works around this bug with very little risk or impact.
