Fix the calls to whatever->open to compile with newer glibc.

The glibc upstream has recently defined open as macro to check for incorrect
usage of the third parameter. This is correct, the POSIX standard says that it
may be declared in such a way. The attached patch redefines all those
> whatever->open(...)
calls to
> (whatever->open)(...)
. I also replaced the close calls, since close may be declared as macro too.
