qt: Support decryption (with verification) directly to/from files

* lang/qt/src/Makefile.am: Add new files.
* lang/qt/src/job.cpp (DecryptVerifyJob): Move definition of constructor
and destructor and inclusion of the moc file to the corresponding .cpp
file.
* lang/qt/src/decryptverifyjob.cpp: New.
* lang/qt/src/decryptverifyjob.h (DecryptVerifyJob): Add member
functions setInputFile, inputFile, setOutputFile, outputFile.
* lang/qt/src/decryptverifyjob_p.h: New.
* lang/qt/src/qgpgmedecryptverifyjob.cpp (class
QGpgMEDecryptVerifyJobPrivate): New.
(QGpgMEDecryptVerifyJob::QGpgMEDecryptVerifyJob): Instantiate private
job class.
(decrypt_verify_from_filename): New.

* lang/qt/tests/Makefile.am: Add new test program.
* lang/qt/tests/run-decryptverifyjob.cpp: New.

This makes it possible to tell gpg to read the input and write the
output directly to a specified file bypassing GpgME's Data IO when
decrypting (and verifying) a file.
