Windows: improve performance via buffered I/O

The posixfile_nt code hits the win32 file API directly, which
essentially amounts to performing a system call for every read and
write. This is slow.

We add a C extension that lets us use a Python file object instead,
but preserve our desired POSIX-like semantics (the ability to rename
or delete a file that is being accessed).

If the C extension is not available (e.g. in a VPS environment
without a compiler), we fall back to the posixfile_nt code.
