* fhandler.h (fhandler_socket::fixup_after_exec): Remove inline 

implementation.
        (fhandler_dev_raw::fixup_after_exec): Ditto.
        * fhandler_raw.cc (fhandler_dev_raw::fixup_after_fork): Don't
        duplicate buffer on fork to avoid memory leak.
        (fhandler_dev_raw::fixup_after_exec): New implementation equal to
        former fixup_after_fork() implementation.
        * fhandler_socket.cc (fhandler_socket::fixup_after_fork): Do
        nothing when not using Winsock2.
        (fhandler_socket::fixup_after_exec): New implementation.
        (fhandler_socket::set_close_on_exec): Never call set_inheritance().
