Windows: Implement a wrapper of the open() function.
The wrapper does two things: - Requests to open /dev/null are redirected to open the nul pseudo file. - A request to open a file that currently exists as a directory on Windows fails with EACCES; this is changed to EISDIR. Signed-off-by: Johannes Sixt <johannes.sixt@telecom.at>
