Fixes rt6_lookup() to provide the source address in the flow
and sets RT6_LOOKUP_F_HAS_SADDR whenever it is present in
the flow.
Avoids unnecessary prefix comparisons by checking for a prefix
length first.
Fixes the rule logic to not match packets if a source selector
has been specified but no source address is available.
Thanks to Kim Nordlund <kim.nordlund@nokia.com> for working
on this patch with me.

Fix mark comparison, also dump the mask to userspace when the mask is
zero, but the mark is not (in which case the mark is dumped, so the
mask is needed to make sense of it).

Add support for fwmark masks.
A mask of 0xFFFFFFFF is used when a mark value != 0 is sent without a mask.

Introduce RTA_TABLE route attribute and FRA_TABLE routing rule attribute
to hold 32 bit routing table IDs. Usespace compatibility is provided by
continuing to accept and send the rtm_table field, but because of its
limited size it can only carry the low 8 bits of the table ID. This
implies that if larger IDs are used, _all_ userspace programs using them
need to use RTA_TABLE.

The callers of fib6_rule_lookup don't expect it to return NULL,
therefore it must return ip6_null_entry whenever fib_rule_lookup fails.

When the lookup in a table returns ip6_null_entry the policy routing lookup
returns it instead of continuing in the next table, which effectively means
it only searches the local table.
