Update types in File API

Make the argument types of the File API match stdio better:

- Change the data buffer to void *, from char *.
- Change FileWrite() data buffer to const on top of that.
- Change amounts to size_t, from int.

In passing, change the FilePrefetch() amount argument from int to
off_t, to match the underlying posix_fadvise().
