qt: Support writing/reading signed/encrypted files directly to/from file

* lang/qt/src/Makefile.am: Add new files.
* lang/qt/src/job.cpp (EncryptJob, SignJob, SignEncryptJob): Move
definition of constructor and destructor and inclusion of the moc file
to the corresponding .cpp files.
* lang/qt/src/encryptjob.cpp (EncryptJob): Define constructor. Define
destructor as default. Include moc file.
* lang/qt/src/encryptjob.cpp, lang/qt/src/encryptjob.h (EncryptJob):
Add member functions setRecipients, recipients, setInputFile, inputFile,
setOutputFile, outputFile, setEncryptionFlags, encryptionFlags.
* lang/qt/src/encryptjob_p.h (EncryptJobPrivate): Add members
m_recipients, m_inputFilePath, m_outputFilePath, m_encryptionFlags.
* lang/qt/src/qgpgmeencryptjob.cpp (encrypt_to_filename): New.
(QGpgMEEncryptJobPrivate::startIt): Start the job with the values
from the member variables.
* lang/qt/src/qgpgmesignencryptjob.cpp (sign_encrypt_to_filename): New.
(QGpgMESignEncryptJobPrivate::startIt): Start the job with the values
from the member variables.
* lang/qt/src/qgpgmesignjob.cpp (class QGpgMESignJobPrivate): New.
(QGpgMESignJob::QGpgMESignJob): Instantiate private job class.
(sign_to_filename): New.
* lang/qt/src/signencryptjob.cpp (SignEncryptJob): Define constructor.
Define destructor as default. Include moc file.
* lang/qt/src/signencryptjob.cpp, lang/qt/src/signencryptjob.h
(SignEncryptJob): Add member functions setSigners, signers,
setRecipients, recipients, setInputFile, inputFile, setOutputFile,
outputFile, setEncryptionFlags, encryptionFlags.
* lang/qt/src/signencryptjob_p.h (SignEncryptJobPrivate): Add members
m_signers, m_recipients, m_inputFilePath, m_outputFilePath,
m_encryptionFlags.
* lang/qt/src/signjob.cpp: New.
* lang/qt/src/signjob.h (SignJob): Add member functions setSigners,
signers, setInputFile, inputFile, setOutputFile, outputFile,
setSigningFlags, signingFlags.
* lang/qt/src/signjob_p.h: New.
* lang/qt/tests/Makefile.am: Add new test programs.
* lang/qt/tests/run-encryptjob.cpp: New.
* lang/qt/tests/run-signjob.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
signing and/or encrypting a file.
