Headers must be free of Q_FOREACH uses if we want to white-list only
those .cpp files that still use Q_FOREACH in order to enable
QT_NO_FOREACH by default.
In common.h, the situation is pretty clear: the loop bodies clearly
don't modify the container being iterated over.
In MyServer, the situation is not clear at all, and this author
doesn't have the time to investigate, so take a copy and iterate over
that (eactly what Q_FOREACH does), and leave a comment.
As a drive-by, fix missing {} around multi-line loop bodies.

The density of Q_FOREACH uses is high here, too high for this author
to tackle in a short amount of time. But they're concentrated in just
a few TUs, so pick a different strategy:
Mark the whole plugin with QT_NO_FOREACH, to prevent new uses from
creeping in, and whitelist the affected TUs by #undef'ing
QT_NO_FOREACH locally, at the top of each file. Since the TUs are part
of a larger executable, this requires these files to be compiled

operator=(~) and assign(~) share similar names but, until now, have not
shared the same functionality. This patch introduces the usage of
QByteArray::assign() within the non-sharing assignment operator to
effectively boost efficiency by reusing the available capacity.
Since these assignment operators are frequently used in many places,
both within Qt and non-Qt code, this patch comes with benchmarks.
The preview of the benchmark results are compared with this patch and
before this patch. The findings indicate a slight enhancement in
performance associated with the assignment operator. Despite the results
displaying only a minor improvement, progress has been made. Therefore
use assign(QByteArrayView) as replacement.
