win32: set binary I/O mode by default

Text mode is default on Windows, which is just bad.

This file also hosts many functions that were extracted from commit
e56b799d6ad8afba4168fffa7218d44c041a72d2
in Git repository, under directory compat. Some functions are
modified/added by me, but usually credits go to Git developers.
