- added wrappers over Qt classes for seamless replacement if Qt is not available
- added bstrlib as submodule
- only UEFIExtract works with this changes for now, others will followa bit later
- added FfsBuilder code and UI, but reconstruction routines for volumes,
files and sections are still not ready
- FfsOps moved to common
- QVector and QPair aren't used anymore, replaces with std::vector and
std::pair
- common classes are now independent from QObject
- next step is to replace QString with CBString from bstrlib
- files split into common and app-specific ones
- messages from parser and finder separated
- ffsEngine split into multiple classes to reduce complexity
- still no image rebuild
