[glib] config.h.win32.in: Clean Up and Update

[Chun-wei Fan <fanchunwei src gnome org>]

commit 53d487e31bc41cca9bca147e02e81b69e404fe07
Author: Chun-wei Fan <fanchunwei src gnome org>

    config.h.win32.in: Clean Up and Update
    
    Merge the parts that has things to do with stdint.h and inttypes.h with
    the !_MSC_VER portions, and add initial support for Visual Studio 2015,
    which added support for C99 snprintf() and vsnprintf().
    
    Not too sure about the !_MSC_VER for C99 snprintf() and vsnprintf(), but
    since this file is mainly for Visual Studio builds, anyways...
