3b3b0910ff Babel: More changes and bugfixes
Several changes and bugfixes in Babel, namely:

- Exported route parameters stored directly in route table entry
- Exported non-babel routes no longer stored in per-entry route list
- Route update, selection and retraction simplified and fixed
- Route feasibility is evalualated per update and stored with route
- Unreachable route handling fixed, based on hold interval
- Added 'show babel routes' command

Overall, it fixes some issues with proper propagation of triggered
updates, making Babel convergence after topology change almost
instant.

dbf1ed263c Babel: Fix handling of seqno requests
Old behavior has several deficiencies compared to standard behavior
(no triggered updates for replies, no retransmissions, ...).

672fb78e12 Babel: Fix handling of IPv4 retractions
Babel TLV parsing code rejected IPv4 retractions without next-hop,
although next-hop is needed just for regular updates.

025525266f Timers: Replace old timers with microsecond timers
The old timer interface is still kept, but implemented by new timers. The
plan is to switch from the old inteface to the new interface, then clean
it up.

f097f7659c OSPF: Fix next hop calculation for PtP links in IPv4 OSPFv3-AF
In such case, next hop has to be taken from Link-LSA like in broadcast
case, not from neighbor source address like in other PtP cases.

Also add some checks, comments and code cleanup.

a1f5e514ef Implement onlink flag for nexthops
Add proper support for per-nexthop onlink flag in routes to handle next
hop addresses that are not covered by interface IP ranges. Supported by
kernel and static protocols.

5220cb63e3 Babel: Fix pointer arithmetic in subtlv parsing
The subtlv parsing code was doing byte-based arithmetic with non-void pointers,
causing it to read beyond the end of the packet.

145ebfa1df Babel: Parse sub-TLVs and skip TLVs with mandatory sub-TLV
RFC6126bis formally introduces sub-TLVs to the Babel protocol, including
mandatory sub-TLVs. This adds support for parsing sub-TLVs to the Babel
protocol and skips TLVs that contain mandatory sub-TLVs, as per the spec.

For details, see section 4.4 of
https://tools.ietf.org/html/draft-ietf-babel-rfc6126bis-02

Thanks to Toke Høiland-Jørgensen <toke@toke.dk> for the patch.

b3c6273efa Babel: Implement IPv6 prefix compression on outgoing updates
Previously, the Babel protocol would never use prefix compression on outgoing
updates (but would parse it on incoming ones). This adds compression of IPv6
addresses of outgoing updates.

The compression only works to the extent that the FIB is walked in lexicographic
order; i.e. a prefix is only compressed if it shares bytes with the previous
prefix in the same packet.

Thanks to Toke Høiland-Jørgensen <toke@toke.dk> for the patch.
