Ingo Klöcker ea6f15ed60
qt: Add simple and extended progress signals replacing old signal 
* lang/qt/src/job.h (Job): Add signals jobProgress and rawProgress.
Deprecate signal progress.
* lang/qt/src/multideletejob.cpp (MultiDeleteJob::slotResult): Emit
new progress signals.
* lang/qt/src/qgpgmerefreshsmimekeysjob.cpp
(QGpgMERefreshSMIMEKeysJob::slotStatus): Ditto.
* lang/qt/src/threadedjobmixin.h (ThreadedJobMixin::showProgress): Use
modern overload of QMetaObject::invokeMethod to forward the progress
signal and add the value of what. Add forwarding of progress to the new
signals.

* lang/qt/tests/t-encrypt.cpp (EncryptionTest::testProgress): Test
the new signals instead of the deprecated one.
--

The new signal jobProgress omits the what value which is useless for
most consumers. The new signal rawProgress makes all information
provided by the backend available to consumers. The latter is not
really meant to be used by users of gpgme. It will be used by the
archive jobs to provide more user-friendly signals.
