MPLS: Label stack concatenation for recursive routes

Static: Protocol rework wrt. struct nexthop changes; MPLS label support

Removing (struct rta)->cast. Never used.

Merge branch 'int-new-rpki-squashed' (early part) into int-new

RPKI protocol with one cache server per protocol

The RPKI protocol (RFC 6810) using the RTRLib
(http://rpki.realmv6.org/) that is integrated inside
the BIRD's code.

Implemeted transports are:
- unprotected transport over TCP
- secure transport over SSHv2...

Merge branch 'master' into int-new

Build: switch on -Wextra, get rid of most of the warnings

There are several unresolved -Wmissing-field-initializers on older
versions of GCC than 5.1, all of them false positive.

rt-table: Fix kernel protocol export filter memory bug

Kernel protocol calls rt_export_merged(), which used @rte_update_pool for
temporary allocations, supposing it is called from other functions from
rt-table.c that handles locking and flushing of the linpool. Therefore,...

Merge remote-tracking branch 'origin/master' into int-new

Merge branch 'int-new' into int-new-merged

Build system reworked to one global Makefile with includes and no nesting

Also removed the lib-dir merging with sysdep. Updated #include's
accordingly.

Fixed make doc on recent Debian together with moving generated doc into
objdir.

Moved Makefile.in into root dir...

Route update: move table lookup from protocols into rte_update2().

Many protocols do almost the same when creating a rte_update request
before calling rte_update2(). This commit should simplify the protocol
side of the route-creation routine.

KRT: Fix route learn scan when route changed

When a kernel route changed, function krt_learn_scan() noticed that and
replaced the route in internal kernel FIB, but after that, function
krt_learn_prune() failed to propagate the new route to the nest, because...

Channels - explicit links between protocols and tables

The patch adds support for channels, structures connecting protocols and
tables and handling most interactions between them. The documentation is
missing yet.

Rewrite roa_check() for integrated BIRD

Thanks to Ondrej Zajicek for his support with writing this code.

Move ID allocator to a separate file and use it also in OSPF

Modify FIB_WALK() and FIB_ITERATE() to work with new FIB code

Returned user data pointers have offset relative to fib_node.

ROA code switchoff

Initial commit on integrated BIRD

New data types net_addr and variants (in lib/net.h) describing
network addresses (prefix/pxlen). Modifications of FIB structures
to handle these data types and changing everything to use these
data types instead of prefix/pxlen pairs where possible....

Minor changes

BGP multipath support

Kernel option 'merge paths' allows to merge routes exported to kernel
protocol (currently BGP and static routes) to multipath routes.

unsigned [int] -> uint

KRT: Add support for plenty of kernel route metrics

Linux kernel route metrics (RTA_METRICS netlink route attribute) are
represented and accessible as new route attributes:

krt_mtu, krt_window, krt_rtt, krt_rttvar, krt_sstresh, krt_cwnd, krt_advmss,
krt_reordering, krt_hoplimit, krt_initcwnd, krt_rto_min, krt_initrwnd,...

Implements show route noexport option.

Shows routes that would be exported to the protocol but are rejected by
the export filter.

Merge branch 'master' into add-path

Conflicts:

filter/filter.c
    nest/proto.c
    nest/rt-table.c
    proto/bgp/bgp.h
    proto/bgp/config.Y

Fixes bug in protocol flushing and rtable pruning.

When route was propagated to another rtable through a pipe and then the
pipe was reconfigured softly in such a way that any subsequent route
updates are filtered, then the source protocol shutdown didn't clean up...

Changes 'rejected' to 'filtered' in one of the last patches.

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.

Implement RA_ACCEPTED mode of route propagation.

Fixes responsiveness for protocol shutdown.

When a protocol went down, all its routes were flushed in one step, that
may block BIRD for too much time. The patch fixes that by limiting
maximum number of routes flushed in one step.

Better support for multitable protocols.

The nest-protocol interaction is changed to better handle multitable
protocols. Multitable protocols now declare that by 'multitable' field,
which tells nest that a protocol handles things related to proto-rtable
interaction (table locking, announce hook adding, reconfiguration of...

Signal problems with route installation to kernel tables.

Prints full community lists during 'show route all'.

Core multipath support.

Implements IGP metric comparison for BGP routes.

Hostcache should use trie to filter relevant route changes.

Implements hostcache and recursive next hops.

Hostcache is a structure for monitoring changes in a routing table that
is used for routes with dynamic/recursive next hops. This is needed for
proper iBGP next hop handling.

Implement proper LSA ID generation.

Changes pipes to transfer all routes between routing table, not just optimal routes.

'show route protocol <p>' added to CLI.

RTS_OSPF_BONDARY is nonsense, RTS_OSPF_IA must have smaller id than RTS_OSPF_EXT

RIP bugfix

FIB documentation.

I've changed the init callback type to a typedef to work around a bug
in kernel-doc I'm too lazy to hunt now.

Better rt dumping.

Fixed a very nasty bug in FIB iterators.

Added fib_route() which does (although very slow) lookup of longest-match
routing in a FIB.

Added more convient interface for ea_find.

What is special about int default;? Compiler chokes on that!

Use preferences properly.

Added commands `show route protocol <p>' and `show route import <p>' which
show the routing table as exported to the protocol given resp. as returned
from its import control hook.

To get handling of filtered extended attributes right (even in the old
`show route where <filter>' command), the get_route_info hook gets an...

Define EAF_ORIGINATED and propagate it properly when merging attribute lists.
