QMessageLogger: make qFatal categorized and streamable
There is no technical reason why qFatal shouldn't support categorized
logging, nor have a streaming version.
There is perhaps an API issue, that is, a streaming syntax may encourage
users to do "too much":
qFatal() << gatherLogs() << saveDatabase() << ...;
and that sounds like a bad idea in case the application is in an
unrecoverable state that requires immedate terminatation (indeed,
through qFatal). I'd err on the side of providing the extra convenience.
This commits adds overloads of QMessageLogger::fatal to support
categorized logging (note that fatal messages cannot be disabled),
the relative qCFatal macro, as well as overloads for streaming.
[ChangeLog][QtCore][QMessageLogger] QMessageLogger::fatal now supports
categorized logging, for instance using the qCFatal(category) macro.
Moreover, qFatal() and qCFatal() now support streaming of values
to be printed in the fatal message.
