Link-local support will need to send ARP packets, but needs more
fine-grained control over the contents. Split the implementation
into 2 parts so link-local can share the code.

Use the NetArpTxPacket for the ARP packet, not to hold what used to
be in NetTxPacket.
This saves a copy and makes the code easier to understand.

Don't force ARP clients to return the MAC address if they don't care

When the network is VLAN or SNAP, net_update_ether() will preserve
the original Ethernet packet header and simply replace the src and
dest MACs and the protocol

Call a built-in dummy if none is registered... don't require
protocols to register a handler (eliminating dummies)
NetConsole now uses the ARP handler when waiting on arp
(instead of needing a #define hack in arp.c)
Clear handlers at the end of net loop

Save the length when it is computed instead of forgetting it and
subtracting pointers to figure it out again.

Rename IP header related things to IP_UDP. The existing definition
of IP_t includes UDP header, so name it to accurately describe the
