af63ad90d6 When adding or changing routes, always supply IFP and IFA so we match 
kernel messages 100%.
Restore purging kernel IPv6 routers.

c5d2e393a5 Move SIOCGIFAFLAG_IN6 into if-bsd as in6_addr_flags 
Add pfx_flush to flush ND6 entries when changing routes.
Both these functions only work for BSD, just stubs on Linux.

This tidies the code a little and fixes changing IPv6 routes on BSD,
although the kernel may complain network is down for a few moments.

873c6af120 FreeBSD isn't buggy with adding new addresses and working out 
if they are new and should be tentative - it was my buggy configuraion
when I upgraded from FreeBSD 8 -> 9.

4c80d49c44 Fix compile on FreeBSD

and a possible error on FreeBSD.

5331b839c9 Store IPv6 link local addresses per interface. 
Listen to kernel messages to account them.
If we don't have a local link address, delay IPv6RS as it just
won#t work until we have a local link address.

5fe587be91 Test BSD kernels for a specific version so we can listen to either 
RTM_NEWADDR for duplicates, or directly on the wire with a maximum
timeout.

Warn about this noisily as there is no reason why the kernel cannot be
easily patched to support this.

d8194bcd39 Check address flags for tentative and duplicates bits for sanity. 
Handle the actual trigger to callout dhcpcd-run-hooks in the DAD callback
instead of on receipt of RTM_NEWADDR directly. This is more code, but it allows
us to use our own DAD engine if we need to.

a8df1b28fb Use the kernel DAD for IPv6 addresses and finish the action once each 
address DAD completes. BSD kernels will require a patch as noted within
the README. The linux netlink part still needs to be written.

66fd5d67f0 Add IPv6 DAD detection. 
Sadly, it seems that userland cannot send from the unspecified address.
This means that for RFC conformancy, we have to rely on the kernel
performing DAD.

eebe9a1887 Improve IPv6 RA support by allowing dhcpcd to manage the address and routes 
instead of the kernel. dhcpcd will only do this if RA is disabled in the kernel
or dhcpcd has been instructed to do this via dhcpcd.conf(5) ipv6ra_own and
ipv6ra_own_default directives.

Send and process IPv6 Neighbor Solicitions and Adverts to prove router
reachability. If a router cannot be reached in this way then it is expired.

When debugging, all ND messages are displayed which will create a lot of log
spam.

To ease packaging, ./configure now accepts LDFLAGS and --enable-static.

126abb55cf Respect each kernel message on carrier change instead of checking carrier 
after receiving the message as it's possible for the kernel to react faster
than dhcpcd.

5ed586386c discover_interfaces now uses getifaddrs instead of OS specific implementation. 
do_interface then becomes do_address and also uses getifaddrs.

Binary size is a little smaller, code size is now a lot smaller.

45b51c7f6c dhcpcd CAN work on IEEE FireWire interfaces. 
However, BPF does not appear to operate on these, so we report the error
and continue.
When BPF supports FireWire for DHCP, dhcpcd will magically start to work.

1abffd5ba5 We can now detected primary addresses added or changed in BSD. 
As such, we can wait for a 3RDPARTY to configure the interface, such as PPP.
We can then take the destination addess and automatically give it a default
route or any other DHCP option such as DNS servers.
This addresses #159.
