Fix more things

- Update a couple unicode data files
- Disable strace during logger calls
- SQLite now uses pread() / pwrite()
- pread() past EOF on NT now returns 0
- Make the NT mmap() and fork() code elegant
- Give NT a big performance boost with memory
- Add many more mmap() tests to prove it works
