Use a packet socket to receive packets.
Combined with the previous change to send on a raw socket
instead of a tunnel interface, this allows us to get rid of the
clat interface and remove all the routing configuration code.

Modify the pseudo-header checksum functions.
- Remove the initial checksum, which we don't use anywhere.
- Add the upper-layer protocol to the IPv6 function. Currently
this is always the same as the next header field in the IPv6
header, but technically it's the upper-layer header after all
the extension headers. This is required to support fragments.

Pass around packet data instead of fds
The current code calls all the translation functions one after
another, accumulating the translated packet into local variables
on the stack and calling writev() at the end. This does not allow
calling the translation functions re-entrantly, which is needed,
for example, to translate ICMP errors (which contain the
packet that caused them). Define a clat_packet type to wrap the
array of iovecs and an enum of packet positions.
Also clean up the code a bit: get rid of a fair bit of duplicated
code (though there is still some left), get rid of some redundant
memcpy statements, fix style issues, etc.

Slightly improve dumping packets
Add a function for dumping iovecs, and make hexdumps clearer by
adding spaces between bytes.

Pass in the length to pseudo checksum functions
Currently, the pseudo-header checksum calculation functions get
the transport layer length from the IP header. This requires that
the length be known at IP header construction time, which
does not allow transport layer translation functions to change
the length of the packet later. Have the transport functions
pass in the size directly.

android clat service
This software provides the nat 4->6 translation needed for the "clat" part of
the 464xlat standard. It is needed for better IPv4 application support while
on an IPv6-only mobile network connection using 464xlat's nat64 (such as
T-Mobile's IPv6 trial).
A general diagram of how 464xlat works:
