This improves the performance of exiv2.exe on TIFF files about 5x The MSVC branch adds mmap.cpp and mman.h - borrowed and slightly touched from KDE - the contribution of KDE is acknowledged and respected (and changes documented) - exv_msvc.h modified to support MM - added support files include/sys to enable compilation on MSVC
