squid-2.7.7

>Description:
It would be nice if rc.subr would get generic setfib(1) support someday,
but www/apache22 also contains specific setfib support, so that seems to
be the way to go for now. This patch adds the squid_fib rc.conf option,
which can be used to run squid with an alternate route table.

This patch was based on the changes in apache22-2.2.9_2, and is lightly
tested (start/stop works both with and without squid_fib set, and it
actually uses the alternate fib).
