Kernel+ping: Only allow superuser to create SOCK_RAW sockets
...
/bin/ping is now setuid-root, and will drop privileges immediately
after opening a raw socket.

LibC+ping: Let's use the traditional timersub() et al prototypes
...
This also fixes the build, since ping.cpp already had a timersub().

IPv4: More work on UDP support.
...
I'm now able to connect to a simple UDP server on my host machine and
exchange some data. Very cool! :^)

Add support for socket send/receive timeouts.
...
Only the receive timeout is hooked up yet. You can change the timeout by
calling setsockopt(..., SOL_SOCKET, SO_RCVTIMEO, ...).
Use this mechanism to make /bin/ping report timeouts.

More work on IPv4 sockets and /bin/ping.
...
It's now actually possible to ping other hosts on the network! :^)
I've switched the "run" script over to starting QEMU with user networking
since that works better for my testing needs right now.

Kernel+LibC+Userland: Yet more networking bringup hacking.
...
All ICMP sockets now receive all ICMP packets. All this buffering is gonna
need some limits and such.
