Better fix of missing AF_INET6? definition in lib/socket.h

Moved the code to sysdep.

Follow-up work on integration

Contains some patches from Jan Moskyto Matejka

Delete ipv6 option from configure

Netlink and BSD: Integrating IPv4 and IPv6

Squashing and minor changes by Ondrej Santiago Zajicek

Netlink: attribute validation before parsing

Wanted netlink attributes are defined in a table, specifying
their size and neediness. Removing the long conditions that did the
validation before.

Also parsing IPv4 and IPv6 versions regardless on the IPV6 macro.

Follow-up commit on integrated BIRD

Use net_addr for interface address prefixes, support net_addr in
configuration parser.

Netlink: Allow more than 256 routing tables.

Since 2.6.19, the netlink API defines RTA_TABLE routing attribute to
allow 32-bit routing table IDs. Using this attribute to index routing
tables at Linux, instead of 8-bit rtm_table field.

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....

IO: Handle fd values too big for select()

If the number of sockets is too much for select(), we should at least
handle it with proper error messages and reject new sockets instead of
breaking the event loop.

Thanks to Alexander V. Chernikov for the patch.

Netlink: Fixes uninitialized variable

Thanks to Pavel Tvrdik for the bugfix

KRT: Fixes some minor bugs in kernel protocol

unsgined char -> byte

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,...

KRT: Fixes learning of preferred kernel routes.

When a new route was imported from kernel and chosen as preferred, then
the old best route was propagated as a withdraw to the kernel protocol.
Under some circumstances such withdraw propagated to the BSD kernel could...

Minor fixes

BGP: Enhanced route refresh (RFC 7313) support

Also hook feed_done is renamed to feed_end.

Implement latency tracking, internal event log and watchdog

Use AF_UNSPEC for RTM_GETLINK

This value is specified in documentation.

Add const to a param msg at functions log_msg, log_rl, die, bug and debug

Version 1.5.0pre

Integrated IP functions.

Implements token bucket filter for rate limiting.

Fixes some warnings.

Fixes a bug in BSD kernel interfacing code.

The bug was introduced in 05476c4d04a24bdb26fa64e05ab31bc36118f34e.

String constants could be used for string option values.

Thanks to Frederik Kriewitz for the patch.

Merge branch 'bgp-grace'

Fixes longstanding issue with interfaces staying in IF_TMP_DOWN.

Thanks to Pierluigi Rolando and others for the bugreport.

Many changes in I/O and OSPF sockets and packet handling.

I/O:
- BSD: specify src addr on IP sockets by IP_HDRINCL
- BSD: specify src addr on UDP sockets by IP_SENDSRCADDR
- Linux: specify src addr on IP/UDP sockets by IP_PKTINFO
- IPv6: specify src addr on IP/UDP sockets by IPV6_PKTINFO...

NEWS and version update.

Changes primary addr selection on BSD to respect SIOCGIFADDR ioctl() result.

Thanks to Alexander V. Chernikov for the original patch.

Minor fix in log_commit() w.r.t. changes in BFD branch.

Fixes problem with RIP on multiple ifaces on BSD.

RIP sockets for multiple ifaces collided, because we cannot bind to
a specific iface on BSD. Workarounded by SO_REUSEPORT.

Thanks to Eugene M. Zheganin for the bugreport.

BFD protocol, ready for release.

Supports OSPF and BGP and also statically configured sessions.

Flag -f "run in foreground" added as requested by a package maintainter.

Implements PID file support.

Thanks to Thierry Fournier for the original patch.

Allows other than IA_PEER addresses on PtP ifaces on BSD.

Also fixes a potential problem with link-local dest_addrs
for IA_PEER addresses.

Thanks to Alexander V. Chernikov for the suggestion.

Fixes a bug in kernel extended attribute processing.

The bug caused that krt_prefsrc attribute was not processed when a route
received from a kernel protocol was exported to another kernel protocol.

Thanks to Sergey Popovich for a bugreport.

NEWS and version update.

Implements eval command and minor CLI cleanups.

Implemented eval command can be used to evaluate expressions.

The patch also documents echo command and allows to use log classes
instead of integer as a mask for echo.

Some fixes for TTL security.

Makes krt.c much more readable.

Better packet priority and traffic class handling.

Implements support for IPv6 traffic class, sets higher priority for OSPF
and RIP outgoing packets by default and allows to configure ToS/DS/TClass
IP header field and the local priority of outgoing packets.
