Ingo Klöcker 7f089165e3 qt: Check arguments passed to the revoke key job
* lang/qt/src/qgpgmerevokekeyjob.cpp (check_arguments): New.
(QGpgMERevokeKeyJob::start, QGpgMERevokeKeyJob::exec): Call
check_arguments.
* lang/qt/tests/t-revokekey.cpp (RevokeKeyJobTest): Add member functions
testErrorHandling_nullKey, testErrorHandling_invalidReason,
testErrorHandling_invalidDescription.
--

Check that the key is not a null key, that the reason has a valid
value, and that the description lines do not contain endline characters
and are not empty.
