e37d2e3e70 Netlink: Ignore tentative addresses
Ignore tentative IPv6 addresses and wait until finish of Duplicate
Address Detection (We got notification when an address is no longer
tentative) to avoid problems when protocols try to use interfaces
with tentative link-local addresses.

c6ed5a0f99 Babel: Do not maintain feasibility distance for our own routes
We do not need to maintain feasibility distances for our own router
ID (we ignore the updates anyway). Not doing so makes the routes be
garbage collected sooner when export filters change.

0f67366601 Babel: Do not keep an infeasible route as selected
When a route becomes infeasible it should not be kept as selected; this
is forbidden by section 3.6 of the RFC and prevents subsequent updates
from the same router ID from replacing it.

5d6ca22085 Babel: Send wildcard retractions on shutdown and startup
This makes BIRD send a wildcard retraction on all interfaces before
shutting down and right after starting up. This helps ensure that
neighbours will discard the announced routes as soon as possible,
rather than only after the normal timeout procedures.

ecae2f43f3 Babel: Rework handling of retractions
An update with wildcard AE and infinite metric should be treated as a
global retraction of all prefixes announced by that neighbour, per
section 4.4.9 of the RFC. In addition, router ID and seqno in retraction
updates should be ignored. This reworks the handling of retractions and
adjusts the parser to handle all this correctly.

321ff8c404 Babel: Make sure intervals do not overflow
Intervals are carried as 16-bit centisecond values, but kept internally
in 16-bit second values, which causes a potential for overflow. This adds
some checks to make sure this does not happen.

775a5a8195 BGP: Skip empty path segments in received AS_PATH

This breaks recvmsg and sendmsg with musl libc on mips64. Fix this by
