Support more than one clatd at a time.
The only change necessary is to stop calling the clat interface
"clat4" and instead name it based on the upstream interface
(specifically, "v4-<interface>".

Call read on any event, not just on POLLIN.
The main clatd event loop calls poll() in a loop, but reads only
from FDs that have POLLIN set. This causes it to get into an
infinite loop if one of the fds has POLLERR set.
Instead, read from all fds that have reported events. The read
causes the kernel to return the error to userspace and clear the
socket error flag, and poll starts working correctly after that.

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.

Use a raw socket to send IPv6 packets instead of a tun.
This will allow us to bind the socket to a particular network.

Move translation entry point into translate.c.
The entry point to the translation code is currently called
packet_handler and lives in clatd.c. Move it into translate.c
and rename it to translate_packet, since that's what it does.
Also get rid of some redundant includes.

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.

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:
