Implement some of the missing LFS64 support.
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).
