'libs/evoral' - DLL visibility stuff and associated changes needed for building with MSVC. Currently includes debugging information and things that are just commented out until we have known compatibility with the other platforms (i.e. contains stuff to be removed at a later date)
'libs/evoral' - Move a couple of 'IdentityConverter' functions into their own dedicated C++ source file. This allows them to be used correctly with __dllimport and __dllexport. Hopefully, this technique will also work for gcc / mingw
