* lang/qt/src/Makefile.am: Add new files and corresponding camel-case header. * lang/qt/src/dataprovider.h: Include interface from gpgme++ when not building. * lang/qt/src/filelistdataprovider.cpp, lang/qt/src/filelistdataprovider.h: New. -- The new data provider simplifies providing a nul-separated list of UTF-8-encoded filenames, e.g. for creating signed or encrypted archives. It is a simple read-only proxy for QByteArrayDataProvider. GnuPG-bug-id: 6342
