FluidSynth and QSynth: Mac OSX status.

Here is a summary of the latest changes I've made to FluidSynth and QSynth in Mac OSX.
  • CoreAudio driver now uses the HAL output AudioUnit. A new function has been added to enumerate existing hardware devices, and an option named "audio.coreaudio.device" with the same functionality as other FluidSynth hardware drivers. It can be selected in QSynth using the audio device combo box.
  • CoreMIDI driver option "" now works much like the equivalent option of the Linux ALSA driver. Added support in QSynth for this setting.
  • FluidSynth has a new CMake boolean option: "enable-framework", default=true. It creates a Mac OSX style "FluidSynth.framework", a type of bundle that includes headers and libraries together (and other resources if required). This framework bundle is installed by default in "/Library/Frameworks". If this option is disabled at configuration time, the build system creates an Unix style dynamic library as before.
  • QSynth has also a CMake build system. It can use either the new framework or the old Unix style dylib. After compilation, you can copy/embed all the used frameworks (including FluidSynth) into the app bundle, running the Qt utility "macdeployqt". To build universal binaries, use a CMake argument like CMAKE_OSX_ARCHITECTURES=i386;ppc (all the dependencies need to be compiled using the same set of architectures).
Pending tasks: testing, packaging, documentation. Opinions?
