Avoid duplicate emulated mouse events with XInput2

When using a touch screen on a Linux machine, we receive both touch-events
and emulated mouse events from XInput, on top of that we synthesize mouse-
events ourselves for the touch events.

This patch grabs the touch device for touch events whenever it processes
a touch-begin thereby avoiding XInput from synthesizing mouse events.

Fix Qt build when mtdev is detected

If it's detected, we have "mtdev" in QT_CONFIG, not in CONFIG. With
the bad test, libQt5PlatformSupport.prl would not get -lmtdev and, in
turn, the evdevtouch generic plugin would fail to link.

XCB: Fix pixmap leak

Fixes: 32 bit and alpha bmp format image reading

The bmp handler would ignore the high byte of a 32bit bmp. It
would also ignore any alpha channel.

The actual change is really simple; it just adds the alpha_* members
and the reading of the 4th byte in 32bit depth. However, detection
of alpha channel required switching the order of two independent
blocks of code, hence the size of this patch.

Use the default height (not 0) if only width is specified

If width was specified, but not height (or vice versa) the actual
window size was not as expected:
* The window width was not the width specified.
* The window height became 0.
This was unexpected, since if both width and height was not specified
it would fallback to becoming 160x160 (on Windows).

However, with the advent of https://codereview.qt-project.org/71999
both width and height might receive sensible defaults based on the
content of the ApplicationWindow, which would mean that it might be
reasonable to expect that you only need to specify one size component
of the window.

This also fixes an assertion in file
..\..\..\3rdparty\angle\src\libGLESv2\renderer\SwapChain9.cpp, line 81
The assertion happened when a window was created with 0 height (but
valid width), and then its height got increased, causing it to become
visible.

Optimize QObject::senderSignalIndex to only iterate the d->senders once.

QObject::senderSignalIndex is, combined with ::sender(), the current
hotspot in the QWebChannel which makes heavy use of it in its 1-to-many
QSignalSpy implementation.

This patch optimizes the senderSignalIndex by only iterating over the
linked senders list once, instead of twice. I.e. it first iterated over
it to find the signal index, then again to find the sender to convert
to a method-offset.
