Ondrej Zajicek 859cbd75e1 Fixes a bug in (mainly) IPv6 BGP.
Stack variable may be used unitialized and that would lead to spurious
rta_free(), which may cause crash. The bug was introduced in 1.4.1 from
merging add-path branch.

Thanks to Peter Andreev for reporting it and Alexander V. Chernikov for
resolving it.

Ondrej Zajicek 094d2bdb79 Implements ADD-PATH extension for BGP.
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.

Hostcache is a structure for monitoring changes in a routing table that

Ondrej Zajicek 82a79586e5 Better handling of too long attributes
This patch extends the length for attributes from 1024 to 2048
(because both AS_PATH and AS4_PATH attributes take 2+4 B per AS).

If there is not enough space for attributes, Bird skips that
route group. Old behavior (skipping remaining attributes)
leads to skipping required attributes and session drop.
