* lang/qt/src/addexistingsubkeyjob.h,
lang/qt/src/qgpgmeaddexistingsubkeyjob.cpp,
lang/qt/src/qgpgmeaddexistingsubkeyjob.h: New.
* lang/qt/src/protocol.h (class Protocol): Add pure virtual member
function addExistingSubkeyJob.
* lang/qt/src/protocol_p.h (Protocol::addExistingSubkeyJob): Implement.
* lang/qt/src/job.cpp, lang/qt/src/Makefile.am: Update accordingly.

* lang/qt/tests/Makefile.am (the_tests, moc_files, noinst_PROGRAMS):
Add new test.
(t_addexistingsubkey_SOURCES): New.
* lang/qt/tests/t-addexistingsubkey.cpp: New.
* lang/qt/tests/t-support.h (VERIFY_OR_RETURN_VALUE,
COMPARE_OR_RETURN_VALUE, VERIFY_OR_OBJECT, COMPARE_OR_OBJECT,
VERIFY_OR_FALSE, COMPARE_OR_FALSE): New.
* lang/qt/tests/t-support.h, lang/qt/tests/t-support.cpp
(class QQGpgMETest): New member function importSecretKeys.

The new job allows adding existing subkeys to other keys as with the
"addkey" edit-key command of gpg. The added subkey will have the same
expiration date (+/- 1 second) as the original subkey.
