Add makedev for the BSDs
Also, make makedev function safe and const on all platforms.
On Android, change the arguments from signed to unsigned integers to
match the other platforms. The C makedev is a macro, so the
signededness is undefined.
Add an integration test for makedev, too, since it's a macro that we
must reimplement.
