[PATCHSET] Multiple IPV6 Routing Tables & Policy Routing

[Thomas Graf <tgraf@suug.ch>]

Hello,

This patchset implements multiple IPv6 routing tables and
policy routing. Even though the code is almost rewritten
entirely the work is based on the MIPL patch found on
mobile-ipv6.org which is being jointly developed by Helsinki
University of Technology (HUT) and the USAGI/WIDE Project.

Reference counting on routing tables was removed to decrease
the number of required atomic operations during route lookup.

The tables are now organized in a hashtable to prepare for
the change in supporting more than 255 tables.

Matching sources address in policy rules is no longer dependant
on CONFIG_SUBTREES.
