tap: Split tap_ip6_send() into UDP and ICMP variants
tap_ip6_send() has special case logic to compute the checksums for UDP
and ICMP packets, which is a mild layering violation. By using a suitable
helper we can split it into tap_udp6_send() and tap_icmp6_send() functions
without greatly increasing the code size, this removing that layering
violation.
We make some small changes to the interface while there. In both cases
we make the destination IPv6 address a parameter, which will be useful
later. For the UDP variant we make it take just the UDP payload, and it
will generate the UDP header. For the ICMP variant we pass in the ICMP
header as before. The inconsistency is because that's what seems to be
the more natural way to invoke the function in the callers in each case.
