This gives us: * <dirent.h> struct dirent64 readdir64, readdir64_r, alphasort64, scandir64 * <fcntl.h> creat64, openat64, open64. * <sys/stat.h> struct stat64 fstat64, fstatat64, lstat64, stat64. * <sys/statvfs.h> struct statvfs64 statvfs64, fstatvfs64. * <sys/vfs.h> struct statfs64 statfs64, fstatfs64. This also removes some of the incorrect #define hacks we've had in the past (for stat64, for example, which we promised to clean up way back in bug 8472078). Bug: 11865851 Bug: 8472078 Change-Id: Ia46443521918519f2dfa64d4621027dfd13ac566
