Protocol: better granularity of pool management

There are now 3 different pools with specific lifetime. All of these are
available since protocol start, anyway they get freed in different
moments.

First, pool_up gets freed immediately after announcing PS_STOP, to e.g.
stop all timers and events regularly updating the routing table when the
imports are already flushing.

Then, pool_inloop gets freed just before the protocol loop is finally
stopped, after all channels, imports and exports and other hooks are
cleaned up.

And finally, the pool itself is freed the last. Unless you explicitly
need the early free, use this pool.

Babel: Add support for the RTT extension

This adds support to the Babel protocol for the RTT extension specified
in draft-ietf-babel-rtt-extension. While this extension is not yet at the
RFC stage, it is one of the more useful extensions to Babel[0], so it
seems worth having in Bird as well.

The extension adds timestamps to Hello and IHU TLVs and uses these to
compute an RTT to each neighbour. An extra per-neighbour cost is then
computed from the RTT based on a minimum and maximum interval and cost
value specified in the configuration. The primary use case for this is
improving routing in a geographically distributed tunnel-based overlay
network.

The implementation follows the babeld implementation when picking
constants and default configuration values. It also uses the same RTT
smoothing algorithm as babeld, and follows it in adding a new 'tunnel'
interface type which enables RTT by default.
