Import qlogger framework
Merge most parts of the qlogger framework from
git://gitorious.org/qtplayground/qlogger.git
The categorized logging feature is a replacement for qDebug, qWarning and
friends. With logging statements in an app/library, a developer can
turn on the statements they care about and turn off the ones they don't.
Most work for this was done by Wolfgang Beck and Lincoln Ramsay.
Task-number: QTBUG-25694
