Revert "Qwt 6 support"

Browse Source 
The patch that was applied was missing a number of critical changes
and needs to be recreated and retested. The majority of qwt was not
uplifted and remained at Qwt 5.

This reverts commit e97aac7919.

\brief Synthetic point data
QwtSyntheticPointData provides a fixed number of points for an interval.
The points are calculated in equidistant steps in x-direction.
If the interval is invalid, the points are calculated for
the "rect of interest", what normally is the displayed area on the
plot canvas. In this mode you get different levels of detail, when
zooming in/out.
\par Example
The following example shows how to implement a sinus curve.
\verbatim
#include <cmath>
#include <qwt_series_data.h>
#include <qwt_plot_curve.h>
#include <qwt_plot.h>
#include <qapplication.h>
class SinusData: public QwtSyntheticPointData

plot.setAxisScale(QwtPlot::yLeft, -1.0, 1.0);
QwtPlotCurve *curve = new QwtPlotCurve("y = sin(x)");
curve->setData(SinusData());

plot.show();

/*!
\brief QwtSystemClock provides high resolution clock time functions.
Sometimes the resolution offered by QTime ( millisecond ) is not accurate
enough for implementing time measurements ( f.e. sampling ).
QwtSystemClock offers a subset of the QTime functionality using higher
resolution timers ( if possible ).
Precision and time intervals are multiples of milliseconds (ms).
\note The implementation uses high-resolution performance counter on Windows,
mach_absolute_time() on the Mac or POSIX timers on other systems.
If none is available it falls back on QTimer.
