* Makefile (SRCS): Add tunnel.c
* tunnel.c: New file.
* linux-src/net/ipv4/devinet.c (configure_device): New argument PEER.
Implement support for setting the destination address for
point-to-point interfaces.
(inquire_device): New argument PEER.
Implement support to get the destination address.
* main.c: Include fcntl.h.
Update prototype of configure_device.
Set trivfs_support_read and trivfs_support_write to 1, as we support
those in some cases now. For the same reason, set trivfs_allow_open
to O_READ | O_WRITE.
(pfinet_demuxer): If the port is not in the socketport_class,
don't try io_server (so requests for trivfs are not catched too early).
(find_device): Use setup_tunnel_device for tun* interfaces.
(main): Add peer argument to configure_device call for the lo interface.
* options.c: Update prototypes for configure_device, inquire_device.
(options): Add --peer option.
(stuct parse_interface): Add peer member.
(parse_hook_add_interface): Initialize peer.
(parse_opt): Add a case for --peer.
Add peer argument to configure_device call.
(add_dev_opts): Add peer variable, add it to inquire_device call arguments.
Check for peer argument and add it to command line if it is there.
* pfinet.h: Add prototype for setup_tunnel_device.
