3f477ccb03 Filters: Function body comparison result now used. 
Function bodies were compared in post-parse time, yet the result was not
used and the functions were incorrectly considered the same as before.

Now the result is used to reload affected protocols.

There is an improper check for valid message size, which may lead to

4fa0e472cf BGP: Use reallocation for capability structure 
Instead of having large stack buffer for max amount of AFI/SAFI pairs.
The old code is not correct w.r.t. extendeded option length, as more
AFI/SAFI pairs may fit into the capability option.

b7d7599ce3 BGP: implement Adj-RIB-Out 
The patch implements optional internal export table to a channel and
hooks it to BGP so it can be used as Adj-RIB-Out. When enabled, all
exported (post-filtered) routes are stored there. An export table can be
examined using e.g. 'show route export table bgp1.ipv4'.

e2b530aa72 BGP: Improve reconfiguration 
Several BGP channel options (including 'next hop self') could be
reconfigured without session reset, with just route refeed/refresh.
The patch improves reconfiguration code to do it that way.

f6a6a77640 BGP: Fix 'deterministic med' to work with 'merge paths' 
The 'deterministic med' option is implemented by suppressing other than
best-in-group routes (grouped by ASN) from best route selection. This
interferes with 'merge paths' as supressed routes are no longer mergable
with best route. This is fixed by suppressing only those routes that are
not mergable with best-in-group route.

96e4d0960c Change 'graceful down' command to 'graceful restart' and update docs 
The command initiating planned graceful restart including bird shutdown
should be called 'graceful restart' instead of 'graceful down', as the
later should be reserved for graceful shutdown in style of RFC 8326.

18f70a6229 Nest: VRF of protocol can be explicitly specified as 'default' 
Protocol can have specified VRF, in such case it is restricted to a set
of ifaces associated with the VRF, otherwise it can use all interfaces.

The patch allows to specify VRF as 'default', in which case it is
restricted to a set of iface not associated with any VRF.

8235c4747d Netlink: Use route replace for IPv4 
Use route replace netlink op instead of delete+add netlink ops for kernel
IPv4 route replace. This avoids some packetloss during route replace.
Still use the old behavior for IPv6, as some kernel bugs are hidden in
IPv6 ECMP handling.
