Use M_PI (and friends), where possible, in favor of hand-coded
approximations of various (in)accuracies. Where that's not available
(e.g. fragment shaders), use the same value that qmath.h uses for
M_PI, for consistency. Replaced math.h with qmath.h in places that
defined a fall-back in case math.h omits it (it's not in the C++
standard, although M_PI is in POSIX); or removed this entirely where
it wasn't used.
Reworked some code to reduce the amount of arithmetic needed, in the
process; e.g. pulling common factors out of loops. Revised an
example's doc to not waste time talking about using a six-sig-fig
value for pi (which we no longer do) - it really wasn't relevant, or
anything to be proud of; nor did the doc mention its later use.

Previously, when clearing the pattern by clicking the clear
button, the result match list would display a list of empty
matches since apparently an empty pattern matches as many
times as the subject is long. This is confusing when using the
tool.
Restructure RegularExpressionDialog::refresh() so that it bails
out if the pattern is empty or invalid.

Use it in the examples to show the best practice.
qOverload currently can't be used because it requires c++14.

A separate flag is no longer needed now that simulator and device builds
are not exclusive any more (*) - both 'simulator' and 'device' being set
at the same time is a sufficient indication (uikit/default_pre.prf sets
this up according to the simulator_and_device feature and the
QMAKE_MAC_SDK variable).
(*) xcodebuild mode actually still uses exclusive builds, but this is
activated locally in uikit/default_post.prf, and uikit/xcodebuild.prf
implements the actual build passes manually anyway, so this change does
not affect it.

Commit c5db8fc74 changed all instances of Q_WS_FOO to have the prefix
Q_DEAD_CODE_FROM_QT4 instead, to make it clearer when reading the code
that the code in question was a left-over from Qt4, when we used
Q_WS_ defines instead of Q_OS_ defines.
This worked well for cases of #ifdef Q_DEAD_CODE_FROM_QT4, but less so
for cases of #ifndef Q_DEAD_CODE_FROM_QT4, where the code was actually
unconditionally included.
To make this even clearer, the defines have been replaced by checks for
1 or 0, with a comment describing how the code used to look in Qt4. The
use of constants in the check also makes it easier for editors to parse
the condition and show visually that the code is defined out.

The examples should show the best practice of having it, as it may save
