Use new compile flag WIN32_VS to add/change logic of sftp client and sftp server codes so that MS Visual Studio 2015 compiler and runtime can be used. opendir(), readdir(), closedir() directory APIs and basename() API of Unix/Linux are implemented in Windows as they are not available in Windows/VisualStudio C-runtime. win32_dirent.c and win32_dirent.h files added as dirent.c and dirent.h are not available in Windows and we do not want to affect mingW/gcc builds for Windows which have those files available.
